         Thanks for taking the time to report a bug.
         
         Please double check some things first:
-        - Do you just have a question about something? If so, asking in the [Q&A Discussions](https://github.com/itzg/docker-minecraft-server/discussions/categories/q-a) or asking on [the Discord server](https://discord.gg/DXfKpjB) would be best.
-        - Is this bug happening after the `[init]` prefixed logs and after the log that says "Starting the Minecraft server"? If so, please report the bug with Mojang or the respective server provider.
-        - Are you seeing a performance problem? If so, that is typically outside the scope of the image setup mechanims. Ask a question as above or contact the respective server provider.

+        2. Did you **re-pull the newest image** and confirmed the issue after that? Run `docker pull <image>` or if using a compose file, it's as easy as running `docker compose pull`. If using Kubernetes, add `imagePullPolicy: Always` to the container.

-## Adding a server type
-
-Adding a new server `TYPE` can vary due to the complexity of obtaining and configuring each type; however, the addition of any server type includes at least the following steps:
-
-1. Copy an existing "start-deploy*" script, such as [start-deployMohist](scripts/start-deployMohist) and rename it accordingly making sure to retain the "start-deploy" prefix
-2. Modify the type-specific behavior between the "start-utils" preamble and the hand-off to `start-setupWorld` at the end of the script 
-3. Develop and test the changes using the [iterative process described below](#iterative-script-development)
-4. Add a case-entry to the `case "${TYPE^^}"` in [start-configuration](scripts/start-configuration)
-5. Add a section to the [README](README.md). It is recommended to copy-modify an existing section to retain a similar wording and level of detail
-6. [Submit a pull request](https://github.com/itzg/docker-minecraft-server/pulls)
-
-## Iterative script development
-
-Individual scripts can be iteratively developed, debugged, and tested using the following procedure.
-
-First, build a baseline of the image to include the packages needed by existing or new scripts:
-
-```shell script
-docker build -t mc-dev .
-```
-
-Using the baseline image, an interactive container can be started to iteratively run the scripts to be developed. By attaching the current workspace directory, you can use the local editor of your choice to iteratively modify scripts while using the container to run them.
-
-```shell script
-docker run -it --rm -v ${PWD}:/scripts -e SCRIPTS=/scripts/ --entrypoint bash mc-dev
-```
-
-From within the container you can run individual scripts via the attached `/scripts/` path; however, be sure to set any environment variables expected by the scripts by either `export`ing them manually:
-
-```shell script
-export VANILLA_VERSION=1.12.2
-/scripts/start-magma
-```
-
-...or pre-pending script execution:
-
-```shell script
-VANILLA_VERSION=1.12.2 /scripts/start-magma
-```
-
-> NOTE: You may want to temporarily add an `exit` statement near the end of your script to isolate execution to just the script you're developing.
-
-## Using development copy of mc-image-helper
-
-In the cloned copy of [`mc-image-helper`](https://github.com/itzg/mc-image-helper), create an up-to-date snapshot build of the tgz distribution using:
-
-```shell
-./gradlew distTar
-```
-
-Assuming [http-server](https://www.npmjs.com/package/http-server) is installed globally, start a static web server using:
-
-```shell
-http-server ./build/distributions -p 0
-```
-
-Note the port that was selected by http-server and pass the build arguments, such as:
-
-```shell
---build-arg MC_HELPER_VERSION=1.8.1-SNAPSHOT \
---build-arg MC_HELPER_BASE_URL=http://host.docker.internal:8080
-```
-
-Now the image can be built like normal and it will install mc-image-helper from the locally built copy.

-Several base-image variants are maintained in order to offer choices in JDK provider and version. The variants are maintained in their respective branches:
-- openj9 
-- openj9-nightly
-- adopt11
-- adopt13
-- multiarch
-
-The [docker-versions-create.sh](docker-versions-create.sh) script is configured with the branches to maintain and is used to merge changes from the master branch into the mulit-base variant branches. The script also manages git tagging the master branch along with the merged branches. So a typical use of the script would be like:
-
-```shell script
-./docker-versions-create.sh -s -t 1.2.0
-```
-
-> Most often the major version will be bumped unless a bug or hotfix needs to be published in which case the patch version should be incremented.
-
-> The build and publishing of those branches and their tags is currently performed within Docker Hub.
-
-## multiarch support
-
-The [multiarch branch](https://github.com/itzg/docker-minecraft-server/tree/multiarch) supports running the image on amd64, arm64, and armv7 (aka RaspberryPi). Unlike the mainline branches, it is based on Ubuntu 18.04 since the openjdk package provided by Ubuntu includes full JIT support on all of the processor types.
-
-The multiarch images are built and published by [a Github action](https://github.com/itzg/docker-minecraft-server/actions?query=workflow%3A%22Build+and+publish+multiarch%22), which [is configured in that branch](https://github.com/itzg/docker-minecraft-server/blob/multiarch/.github/workflows/build-multiarch.yml).
-
-## Generating release notes
-
-The following git command can be used to provide the bulk of release notes content:
-
-```shell script
-git log --invert-grep --grep "^ci:" --grep "^misc:" --grep "^docs:" --pretty="* %s" 1.1.0..1.2.0
-```
-## Tracking changes from master without content
-
-The following script uses the [ours](https://git-scm.com/docs/merge-strategies#Documentation/merge-strategies.txt-ours) merging strategy to track the history from master into the other branches without actually bringing the changes over. It is useful when a change is specific to master only, such as bumping the base Java version for the `latest` image tag.
-
-```shell
-branches=(
-  java8
-  java8-multiarch
-  java8-openj9
-  java11
-  java11-openj9
-  java16
-  java16-openj9
-  java17
-)
-
-for b in "${branches[@]}"; do
-  git checkout "$b"
-  git merge -s ours -m "Track latest from master" master
-  git push origin
-done
-```

+# Auto-execute RCON commands
+
+RCON commands can be configured to execute when the server starts, a client connects, or a client disconnects.
+
+!!! note
+
+    When declaring several commands within a compose file environment variable, it's easiest to use YAML's `|-` [block style indicator](https://yaml-multiline.info/).
+
+**On Server Start:**
+
+``` yaml
+      RCON_CMDS_STARTUP:  |-
+        gamerule doFireTick false
+        pregen start 200
+```
+
+**On Client Connection:**
+
+``` yaml
+      RCON_CMDS_ON_CONNECT:  |-
+        team join New @a[team=]
+```
+
+**Note:**
+* On client connect we only know there was a connection, and not who connected. RCON commands will need to be used for that.
+
+**On Client Disconnect:**
+
+``` yaml
+      RCON_CMDS_ON_DISCONNECT:  |-
+        gamerule doFireTick true
+```
+
+**On First Client Connect**
+
+``` yaml
+      RCON_CMDS_FIRST_CONNECT: |-

+title: Modifying config files
+---
+
+## Replacing variables inside configs
+
+Sometimes you have mods or plugins that require configuration information that is only available at deploy-time. For example if you need to configure a plugin to connect to a database, you don't want to include this information in your Git repository or Docker image.
+Or maybe you have some runtime information like the server name that needs to be set in your config files after the container starts.
+
+For those cases there is the option to replace defined variables inside your configs with environment variables defined at container runtime.
+
+When the environment variable `REPLACE_ENV_IN_PLACE` is set to `true` (the default), the startup script will go through all files inside the container's `/data` path and replace variables that match the container's environment variables. Variables can instead (or in addition to) be replaced in files sync'ed from `/plugins`, `/mods`, and `/config` by setting `REPLACE_ENV_DURING_SYNC` to `true` (defaults to `false`).
+
+Variables that you want to replace need to be declared inside curly brackets and prefixed with a dollar sign, such as  `${CFG_YOUR_VARIABLE}`, which is same as many scripting languages.
+
+You can also change `REPLACE_ENV_VARIABLE_PREFIX`, which defaults to "CFG_", to limit which environment variables are allowed to be used. For example, with "CFG_" as the prefix, the variable `${CFG_DB_HOST}` would be substituted, but not `${DB_HOST}`. The prefix can be set to an empty string to allow for matching any variable name.
+
+If you want to use a file's content for value, such as when using secrets mounted as files, declare the placeholder named like normal in the file and declare an environment variable named the same but with the suffix `_FILE`.
+
+For example, a `my.cnf` file could contain:
+
+```toml
+[client]
+password = ${CFG_DB_PASSWORD}
+```
+
+...a secret declared in the compose file with:
+```yaml
+secrets:
+  db_password:
+    external: true
+```
+
+...and finally the environment variable would be named with a `_FILE` suffix and point to the mounted secret:
+```yaml
+    environment:
+      CFG_DB_PASSWORD_FILE: /run/secrets/db_password
+```
+
+Variables will be replaced in files with the following extensions:
+`.yml`, `.yaml`, `.txt`, `.cfg`, `.conf`, `.properties`.
+
+Specific files can be excluded by listing their name (without path) in the variable `REPLACE_ENV_VARIABLES_EXCLUDES`.
+
+Paths can be excluded by listing them in the variable `REPLACE_ENV_VARIABLES_EXCLUDE_PATHS`. Path
+excludes are recursive. Here is an example:
+```
+REPLACE_ENV_VARIABLES_EXCLUDE_PATHS="/data/plugins/Essentials/userdata /data/plugins/MyPlugin"
+```
+
+Here is a full example where we want to replace values inside a `database.yml`.
+
+```yaml
+---
+database:
+  host: ${CFG_DB_HOST}
+  name: ${CFG_DB_NAME}
+  password: ${CFG_DB_PASSWORD}
+```
+
+This is how your `compose.yaml` file could look like:
+
+```yaml title="compose.yaml"
+# Other docker compose examples in /examples
+
+services:
+  minecraft:
+    image: itzg/minecraft-server
+    ports:
+      - "25565:25565"
+    volumes:
+      - "mc:/data"
+    environment:
+      EULA: "TRUE"
+      ENABLE_RCON: "true"
+      RCON_PASSWORD: "testing"
+      RCON_PORT: 28016
+      # enable env variable replacement
+      REPLACE_ENV_VARIABLES: "TRUE"
+      # define an optional prefix for your env variables you want to replace
+      ENV_VARIABLE_PREFIX: "CFG_"
+      # and here are the actual variables
+      CFG_DB_HOST: "http://localhost:3306"
+      CFG_DB_NAME: "minecraft"
+      CFG_DB_PASSWORD_FILE: "/run/secrets/db_password"
+
+volumes:
+  mc:
+  rcon:
+
+secrets:
+  db_password:
+    file: ./db_password
+```
+
+## Patching existing files
+
+JSON path based patches can be applied to one or more existing files by setting the variable `PATCH_DEFINITIONS` to the path of a directory that contains one or more [patch definition json files](https://github.com/itzg/mc-image-helper#patchdefinition) or a [patch set json file](https://github.com/itzg/mc-image-helper#patchset). 
+
+The `file` and `value` fields of the patch definitions may contain `${...}` variable placeholders. The allowed environment variables in placeholders can be restricted by setting `REPLACE_ENV_VARIABLE_PREFIX`, which defaults to "CFG_".
+
+The following example shows a patch-set file where various fields in the `paper.yaml` configuration file can be modified and added:
+
+```json
+{
+  "patches": [
+    {
+      "file": "/data/paper.yml",
+      "ops": [
+        {
+          "$set": {
+            "path": "$.verbose",
+            "value": true
+          }
+        },
+        {
+          "$set": {
+            "path": "$.settings['velocity-support'].enabled",
+            "value": "${CFG_VELOCITY_ENABLED}",
+            "value-type": "bool"
+          }
+        },
+        {
+          "$put": {
+            "path": "$.settings",
+            "key": "my-test-setting",
+            "value": "testing"
+          }
+        }
+      ]
+    }
+  ]
+}
+```
+
+Supports the file formats:
+- JSON
+- JSON5
+- Yaml
+- TOML, but processed output is not pretty

+# JVM Options
+
+## Memory Limit
+
+By default, the image declares an initial and maximum Java memory-heap limit of 1 GB. There are several ways to adjust the memory settings:
+
+- `MEMORY`: "1G" by default, can be used to adjust both initial (`Xms`) and max (`Xmx`) memory heap settings of the JVM
+- `INIT_MEMORY`: independently sets the initial heap size
+- `MAX_MEMORY`: independently sets the max heap size
+
+The values of all three are passed directly to the JVM and support format/units as `<size>[g|G|m|M|k|K]`.
+
+To have control over heap size, without relying on absolute memory sizes percentages are also supported using `<size>%`.
+
+!!! info "RAMPercentage parameters"
+    Percentage based heap sizing is enabled using `-XX:InitialRAMPercentage` for `INIT_MEMORY` and `-XX:MaxRAMPercentage` for `MAX_MEMORY`.
+    For details on the function of these parameters look [here](https://www.baeldung.com/java-jvm-parameters-rampercentage).
+
+!!! example "Using docker run"
+
+    ```
+        -e MEMORY=2G
+    ```
+
+    or to use init and max memory:
+
+    ```
+        -e INIT_MEMORY=1G -e MAX_MEMORY=4G
+    ```
+
+!!! example "Using compose file"
+
+    ```
+        environment:
+          MEMORY: 2G
+    ```
+
+    or to use init and max memory:
+
+    ```
+        environment:
+          INIT_MEMORY: 1G
+          MAX_MEMORY: 4G
+    ```
+
+To let the JVM calculate the heap size from the container declared memory limit, unset `MEMORY` with an empty value, such as `-e MEMORY=""`. By default, the JVM will use 25% of the container memory limit as the heap limit.
+
+!!! important
+    The settings above only set the Java **heap** limits. Memory resource requests and limits on the overall container should also account for non-heap memory usage. An extra 25% is [a general best practice](https://dzone.com/articles/best-practices-java-memory-arguments-for-container).
+
+## Extra JVM Options
+
+General JVM options can be passed to the Minecraft Server invocation by passing a `JVM_OPTS`
+environment variable. If needing to set `-XX` options, then pass those with the `JVM_XX_OPTS` variable instead. Both variables accept space-delimited, raw JVM arguments.
+
+```
+docker run ... -e JVM_OPTS="-XsomeJVMOption -DpropName=value" ...
+```
+
+**NOTE** When declaring `JVM_OPTS` in a compose file's `environment` section with list syntax, **do not** include the quotes:
+
+```yaml
+    environment:
+      - EULA=true
+      - JVM_OPTS=-XsomeJVMOption -DpropName=value
+```
+
+Using object syntax is recommended and more intuitive:
+
+```yaml
+    environment:
+      EULA: "true"
+      JVM_OPTS: "-XsomeJVMOption -DpropName=value"
+# or without quotes
+#     JVM_OPTS: -XsomeJVMOption -DpropName=value
+```
+
+As a shorthand for passing several system properties as `-D` arguments, you can instead pass a comma separated list of `name=value` or `name:value` pairs with `JVM_DD_OPTS`. (The colon syntax is provided for management platforms like Plesk that don't allow `=` inside a value.)
+
+For example, instead of passing
+
+```yaml
+  JVM_OPTS: -Dfml.queryResult=confirm -Dname=value
+```
+
+you can use
+
+```yaml
+  JVM_DD_OPTS: fml.queryResult=confirm,name=value
+```
+
+## Enable Remote JMX for Profiling
+
+To enable remote JMX, such as for profiling with VisualVM or JMC, set the environment variable `ENABLE_JMX` to "true", set `JMX_HOST` to the IP/host running the Docker container, and add a port forwarding of TCP port 7091, such as:
+
+!!! example
+
+    With `docker run`
+
+    ```
+    -e ENABLE_JMX=true -e JMX_HOST=$HOSTNAME -p 7091:7091
+    ```
+
+If needing to map to a different port, then also set the environment variable `JMX_PORT` to the desired host port.
+
+!!! example
+
+    With a compose file:
+
+    ```yaml
+    environment:
+      ENABLE_JMX: true
+      JMX_HOST: ${HOSTNAME}
+      JMX_PORT: "7092"
+    ports:
+      - "7092:7092"
+    ```
+
+## Enable Aikar's Flags
+
+[Aikar has done some research](https://aikar.co/2018/07/02/tuning-the-jvm-g1gc-garbage-collector-flags-for-minecraft/) into finding the optimal JVM flags for GC tuning, which becomes more important as more users are connected concurrently. [PaperMC also has an explanation](https://docs.papermc.io/paper/aikars-flags) of what the JVM flags are doing.
+
+The set of flags documented there can be added using
+
+    -e USE_AIKAR_FLAGS=true
+
+When `MEMORY` is greater than or equal to 12G, then the Aikar flags will be adjusted according to the article.
+
+## Enable MeowIce's Flags
+
+[MeowIce has created an updated set of JVM flags](https://github.com/MeowIce/meowice-flags?tab=readme-ov-file#why-would-i-have-to-switch-) based on Aikar's flags but with support for optimizations for Java 17 and above
+
+The set of flags documented there can be added by setting the environment variable `USE_MEOWICE_FLAGS` to `true`. There is an optional `USE_MEOWICE_GRAALVM_FLAGS` variable to enable GraalVM specific optimizations, defaults to `FALSE`.

+## Running with a custom server JAR
+
+If you would like to run a custom server JAR, set `-e TYPE=CUSTOM` and pass the custom server
+JAR via `CUSTOM_SERVER`. It can either be a URL or a container path to an existing JAR file.
+
+If it is a URL, it will only be downloaded into the `/data` directory if it wasn't already. As
+such, if you need to upgrade or re-download the JAR, then you will need to stop the container,
+remove the file from the container's `/data` directory, and start again.
+
+## Force re-download of the server file
+
+For VANILLA, FORGE, BUKKIT, SPIGOT, PAPER, CURSEFORGE, SPONGEVANILLA server types, set
+`$FORCE_REDOWNLOAD` to some value (e.g. 'true) to force a re-download of the server file for
+the particular server type. by adding a `-e FORCE_REDOWNLOAD=true` to your command-line.
+
+For example, with Paper, it would look something like this:
+
+```
+docker run -d --pull=always \
+    -v /path/on/host:/data \
+    -e TYPE=PAPER -e FORCE_REDOWNLOAD=true \
+    -p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
+```
+
+## Running as alternate user/group ID
+
+By default, the container will switch to and run the Minecraft server as user ID 1000 and group ID 1000; however, that can be changed by setting the environment variables `UID` and `GID`.
+
+The startup will also skip user switching if the `--user`/`-u` argument is passed to `docker run` or `user` is set on the compose service.
+
+## Extra Arguments
+
+Arguments that would usually be passed to the jar file (those which are written after the filename) can be passed via the `EXTRA_ARGS` environment variable.
+
+See [Custom worlds directory path](../misc/world-data.md#custom-worlds-directory-path) for an example.
+
+## Interactive and Color Console
+
+When RCON is enabled, which is the default, and [TTY](https://docs.docker.com/compose/compose-file/05-services/#tty) is enabled on the container, then some server types will output colorized logs and provide a fully interactive console. To access the interactive console, use [`docker attach`](https://docs.docker.com/engine/reference/commandline/container_attach/) (not `exec`). When finished, make sure to use the sequence Control-P, Control-Q to detach without stopping the container.
+
+If this behavior interferes with the log content, then disable TTY or remove the setting entirely since the default is disabled. In a compose file, set the service's `tty` parameter to `false`. On the `docker run` command-line remove the `-t` argument.
+
+## Server Shutdown Options
+
+To allow time for players to finish what they're doing during a graceful server shutdown, set `STOP_SERVER_ANNOUNCE_DELAY` to a number of seconds to delay after an announcement is posted by the server.
+
+!!! warning "Increase stop grace period"
+
+    The Docker stop grace period must be increased to a value longer than the announce delay. The value to use that is longer than announce delay will vary based upon the amount of time it takes for final world data saving. If the container exits with exit code 137, then that indicates a longer grace period is needed. 
+    
+    The grace period can be increased using [the -t option on `docker compose down`](https://docs.docker.com/compose/reference/down/) or set the [stop_grace_period](https://docs.docker.com/compose/compose-file/05-services/#stop_grace_period) in the compose file.
+
+The `STOP_SERVER_ANNOUNCE_DELAY` can be bypassed by sending a `SIGUSR1` signal to the `mc-server-runner` process.
+
+`docker`:
+
+        docker stop --signal SIGUSR1 mc
+
+`docker compose`:
+
+        docker compose kill --signal SIGUSR1
+
+## Configuration Options for Minecraft Server Health Monitoring
+
+The image tags include specific variables to simplify configuration for monitoring the health of a Minecraft server:
+
+- `-e SERVER_HOST=localhost` : This variable sets the host address of the Minecraft server to be monitored. By default, it is set to `localhost`, but you can replace it with the actual hostname or IP address of your Minecraft server.
+
+- `-e SERVER_PORT=25565` : This variable sets the port number on which the Minecraft server is running. By default, Minecraft servers run on port 25565, but if your server is configured to use a different port, you should replace `25565` with the correct port number. This helps the monitoring system to accurately check the health status of the Minecraft server on the specified port.
+
+## OpenJ9 Specific Options
+
+The openj9 image tags include specific variables to simplify configuration:
+
+- `-e TUNE_VIRTUALIZED=TRUE` : enables the option to
+  [optimize for virtualized environments](https://www.eclipse.org/openj9/docs/xtunevirtualized/)
+- `-e TUNE_NURSERY_SIZES=TRUE` : configures nursery sizes where the initial size is 50%
+  of the `MAX_MEMORY` and the max size is 80%.
+
+## Customizing log4j2 configuration
+
+The image now uses a templated log4j2 configuration based on PaperMC's logging setup, which is automatically applied for versions that don't require Log4j security patches. This configuration provides rolling logs and advanced logging features by default.
+
+### Customization via environment variables
+
+You can customize various aspects of the logging behavior using environment variables:
+
+- `LOG_LEVEL` : Root logger level (default: `info`)
+  ```
+  -e LOG_LEVEL=debug
+  ```
+
+- `ROLLING_LOG_FILE_PATTERN` : Pattern for rolled log file names (default: `logs/%d{yyyy-MM-dd}-%i.log.gz`)
+  ```
+  -e ROLLING_LOG_FILE_PATTERN="logs/archive/%d{yyyy-MM-dd}-%i.log.gz"
+  ```
+
+- `ROLLING_LOG_MAX_FILES` : Maximum number of archived log files to keep (default: `1000`)
+  ```
+  -e ROLLING_LOG_MAX_FILES=30
+  ```
+
+### Customizing log message formats
+
+For full control over how log messages are formatted, you can customize the Log4j2 pattern layouts using these variables. These use [Log4j2 Pattern Layout syntax](https://logging.apache.org/log4j/2.x/manual/layouts.html#PatternLayout):
+
+- `LOG_CONSOLE_FORMAT` : Format for console output (what you see in `docker logs`)
+  Default: `[%d{HH:mm:ss}] [%t/%level]: %msg%n`
+
+- `LOG_FILE_FORMAT` : Format for file logs (written to `logs/latest.log`)
+  Default: `[%d{HH:mm:ss}] [%t/%level]: %msg%n`
+
+- `LOG_TERMINAL_FORMAT` : Format for interactive terminal console (used with `docker attach`)
+  Default: `[%d{HH:mm:ss} %level]: %msg%n`
+
+### Example configurations
+
+Simple timestamp customization (most common use case):
+```yaml
+environment:
+  # What you see in docker logs
+  LOG_CONSOLE_FORMAT: "[%d{yyyy-MM-dd HH:mm:ss.SSS}] [%t/%level]: %msg%n"
+  # What gets written to logs/latest.log
+  LOG_FILE_FORMAT: "[%d{yyyy-MM-dd HH:mm:ss.SSS}] [%t/%level]: %msg%n"
+```
+
+Advanced customization:
+```yaml
+environment:
+  LOG_LEVEL: debug
+  # Custom ISO8601 format with logger names
+  LOG_CONSOLE_FORMAT: "%d{ISO8601} %-5level [%t] %logger{36} - %msg%n"
+  LOG_FILE_FORMAT: "%d{ISO8601} %-5level [%t] %logger{36} - %msg%n"
+  ROLLING_LOG_MAX_FILES: 50
+```
+
+### Legacy ENABLE_ROLLING_LOGS option
+
+The `ENABLE_ROLLING_LOGS` environment variable is no longer needed for most use cases, as rolling logs are now enabled by default through the templated configuration. This option is maintained for backward compatibility but is only checked for error reporting when rolling logs cannot be used due to Log4j security patches.
+
+> **NOTE** The templated log4j2 configuration may interfere with interactive/color consoles [as described in the section above](#interactive-and-color-console)
+
+## Timezone Configuration
+
+You can configure the timezone to match yours by setting the `TZ` environment variable:
+
+        -e TZ=Europe/London
+
+such as:
+
+        docker run -d -it --pull=always -e TZ=Europe/London -p 25565:25565 --name mc itzg/minecraft-server
+
+Or mounting `/etc/timezone` as readonly (not supported on Windows):
+
+        -v /etc/timezone:/etc/timezone:ro
+
+such as:
+
+        docker run -d -it --pull=always -v /etc/timezone:/etc/timezone:ro -p 25565:25565 --name mc itzg/minecraft-server
+
+## HTTP Proxy
+
+You may configure the use of an HTTP/HTTPS proxy by passing the proxy's "host:port" via the environment variable `PROXY`. In [the example compose file](https://github.com/itzg/docker-minecraft-server/blob/master/examples/docker-compose-proxied.yml) it references a Squid proxy. The host and port can be separately passed via the environment variables `PROXY_HOST` and `PROXY_PORT`. A `|` delimited list of hosts to exclude from proxying can be passed via `PROXY_NON_PROXY_HOSTS`.
+
+## Using "noconsole" option
+
+Some older versions (pre-1.14) of Spigot required `--noconsole` to be passed when detaching stdin, which can be done by setting `-e CONSOLE=FALSE`.
+
+## Explicitly disable GUI
+
+Some older servers get confused and think that the GUI interface is enabled. You can explicitly
+disable that by passing `-e GUI=FALSE`.
+
+## Stop Duration
+
+When the container is signaled to stop, the Minecraft process wrapper will attempt to send a "stop" command via RCON or console and waits for the process to gracefully finish. By default, it waits 60 seconds, but that duration can be configured by setting the environment variable `STOP_DURATION` to the number of seconds.
+
+Be sure to also increase the shutdown timeout described [here for docker compose down](https://docs.docker.com/reference/cli/docker/compose/down/#options) and [here for docker stop](https://docs.docker.com/reference/cli/docker/container/stop/#options).
+
+## Setup only
+
+If you are using a host-attached data directory, then you can have the image setup the Minecraft server files and stop prior to launching the server process by setting `SETUP_ONLY` to `true`. 
+    
+## Enable Flare Flags
+    
+To enable the JVM flags required to fully support the [Flare profiling suite](https://blog.airplane.gg/flare), set the following variable:
+    
+    -e USE_FLARE_FLAGS=true
+    
+Flare is built-in to Pufferfish/Purpur, and is available in [plugin form](https://github.com/TECHNOVE/FlarePlugin) for other server types.
+
+## Enable support for optimized SIMD operations
+
+To enable support for optimized SIMD operations, the JVM flag can be set with the following variable:
+
+    -e USE_SIMD_FLAGS=true
+
+SIMD optimized operations are supported by Pufferfish and Purpur.
+
+For example, to download configuration files for plugins:
+
+```yaml
+environment:
+  DOWNLOAD_EXTRA_CONFIGS: |
+    plugins/WorldEdit<https://raw.githubusercontent.com/EngineHub/WorldEdit/refs/heads/version/7.3.x/worldedit-bukkit/src/main/resources/defaults/config.yml
+    plugins/EssentialsX<https://raw.githubusercontent.com/EssentialsX/Essentials/refs/heads/2.x/Essentials/src/main/resources/config.yml
+```
+
+Or as a single line:
+
+```yaml
+environment:
+  DOWNLOAD_EXTRA_CONFIGS: "plugins/WorldEdit<https://example.com/worldedit.yml,config<https://example.com/another.yml"
+```
+
+The files will be downloaded to `/data/` relative paths, so `plugins/WorldEdit` will be saved as `/data/plugins/WorldEdit/config.yml`.
+
+!!! note 
+    The downloaded files can be further processed using [environment variable replacement](interpolating.md) or [patch definitions](interpolating.md#patching-existing-files)
+
+## Enable timestamps in init logs
+
+Before the container starts the Minecraft Server its output is prefixed with `[init]`, such as
+
+```
+[init] Starting the Minecraft server...
+```
+
+To also include the timestamp with each log, set `LOG_TIMESTAMP` to "true". The log output will then look like:
+
+```
+[init] 2022-02-05 16:58:33+00:00 Starting the Minecraft server...
+```

docs/configuration/server-properties.md

+In order to unify management of the Minecraft server container, all of the [`server.properties`](https://minecraft.wiki/w/Server.properties) entries can be managed by the environment variables described in the sections below. Some of the mappings provide additional functionality above and beyond the properties file.
+
+If you prefer to manually manage the `server.properties` file, set `OVERRIDE_SERVER_PROPERTIES` to "false". Similarly, you can entirely skip the startup script's creation of `server.properties` by setting `SKIP_SERVER_PROPERTIES` to "true".
+
+!!! note
+  
+    To clear a server property, set the variable to an empty string, such as `-e RESOURCE_PACK=""`. An unset variable is ignored and the existing server property is left unchanged.
+
+To see what `server.properties` will get used by the server, set the environment variable `DUMP_SERVER_PROPERTIES` to "true" and the contents of `server.properties` will get output before the server starts.
+
+## Placeholders
+
+When declaring a server properties via container environment variables, those values may contain placeholders that are processed when the `server.properties` file is updated. 
+
+The syntax of placeholders is DOS-style, `%VAR%`, to avoid being processed by Docker or the shell and the following options are available:
+
+`%VAR%` or `%env:VAR%`
+
+: Replaced with the resolved value or the environment variable `VAR`
+
+`%date:FMT%`
+
+: Formats the current date/time with the given `FMT` string processed by [Java's DateTimeFormatter](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/time/format/DateTimeFormatter.html).
+
+Any declared or resolved environment variable may be referenced, such as `VERSION` and `TYPE`. Additionally, [Modrinth](../types-and-platforms/mod-platforms/modrinth-modpacks.md) and [Auto CurseForge](../types-and-platforms/mod-platforms/auto-curseforge.md) modpacks will expose the environment variables `MODPACK_NAME` and `MODPACK_VERSION`. The originally declared version, such as "LATEST" or "SNAPSHOT", is available in the variable `DECLARED_VERSION` 
+
+!!! example
+
+    As a compose file environment entry:
+
+    ```yaml
+        MOTD: Running %MODPACK_NAME% version %env:MODPACK_VERSION%
+        LEVEL: world-%date:yyyy-MM-dd%
+    ```
+
+!!! warning
+
+    Placeholders are not supported when manually managing `server.properties`
+
+## Properties
+
+### Message of the Day
+
+The message of the day, shown below each server entry in the client UI, can be changed with the `MOTD` environment variable or a default is computed from the server type and version, such as
+
+    A Paper Minecraft Server powered by Docker
+
+That way you can easily differentiate between several server types you may have started.
+
+The section symbol (§) and other unicode characters are automatically converted to allow [formatting codes](https://minecraft.wiki/w/Formatting_codes) to be used consistently with all server versions. For Minecraft versions less than 1.20, unicode characters in `server.properties` will be escaped as `\uXXXX`, by default. That behavior can be altered by setting `SERVER_PROPERTIES_ESCAPE_UNICODE` to "true" or "false".
+
+!!! example
+
+    With `docker run`
+    
+         -e MOTD="A §l§cMinecraft§r §nserver"
+    
+    or within a compose file
+    
+        environment:
+          MOTD: "A §l§cMinecraft§r §nserver"
+
+    renders
+    
+    ![](../img/motd-example.png)
+
+To produce a multi-line MOTD, embed a newline character as `\n` in the string, such as the following example.
+
+!!! example "Multi-line MOTD"
+
+    With `docker run`
+    
+    ```
+    -e MOTD="Line one\nLine two"
+    ```
+    
+    or within a compose file
+    
+    ```yaml
+          MOTD: |
+            line one
+            line two
+    # or
+    #      MOTD: "line one\nline two"
+    ```
+
+The following example combines a multi-line MOTD with [placeholders](#placeholders) from the latest version of the installed modpack:
+
+!!! example
+
+    ```yaml
+    MOD_PLATFORM: AUTO_CURSEFORGE
+    CF_SLUG: craftoria
+    MOTD: |
+      A %TYPE% server on %VERSION%
+      running %MODPACK_NAME% %MODPACK_VERSION%
+    ```
+    
+    ![](../img/motd-with-placeholders.png)
+
+### Difficulty
+
+The difficulty level (default: `easy`) can be set like:
+
+```
+docker run -d -e DIFFICULTY=hard ...
+```
+
+Valid values are: `peaceful`, `easy`, `normal`, and `hard`, and an
+error message will be output in the logs if it's not one of these
+values.
+
+Refer to [the Minecraft wiki](https://minecraft.wiki/w/Difficulty)
+
+### Whitelist Players
+
+!!! warning "For public servers" 
+    
+    It is very important to consider setting a whitelist of expected players.
+
+To whitelist players for your Minecraft server, you can:  
+
+- Provide a list of usernames and/or UUIDs separated by commas or newlines via the `WHITELIST` environment variable
+- Provide the URL or container path to a whitelist file via `WHITELIST_FILE` that will be retrieved/copied into the standard location
+
+!!! example 
+
+    In a compose file, a text block can be used to improve maintainability, such as
+
+    ```yaml
+          WHITELIST: |
+            user1
+            user2
+            user3
+    ```
+
+When either is set, [whitelisting of connecting users](https://minecraft.wiki/w/Server.properties#white-list) is enabled.
+
+To change the behavior when the whitelist file already exists, set the variable `EXISTING_WHITELIST_FILE` to one of the following options:
+
+`SKIP`
+: Skip processing of the whitelist file when one is already present. This is the same as setting the legacy variable `OVERRIDE_WHITELIST` to "false".
+
+`SYNCHRONIZE`
+: Synchronize the list of users in the file with the `WHITELIST` or `WHITELIST_FILE` provided. When using both, `WHITELIST` will take precedence. This is the same as setting the legacy variable `OVERRIDE_WHITELIST` to "true".
+
+`MERGE`
+: Merge the list of users from `WHITELIST` into the existing file. `WHITELIST_FILE` cannot be used with this option.
+
+`SYNC_FILE_MERGE_LIST` (default)
+: When `WHITELIST_FILE` is provided it will overwrite an existing whitelist file. Also, if `WHITELIST` is provided, then those users will be merged into the newly copied file.
+
+!!! note 
+
+    For versions prior to 1.7.3, `white-list.txt` will be maintained instead. Only usernames are supported for those versions.
+
+To [enforce the whitelist changes immediately](https://minecraft.wiki/w/Server.properties#enforce-whitelist) when whitelist commands are used , set `ENFORCE_WHITELIST` to "true". If managing the whitelist file manually, `ENABLE_WHITELIST` can be set to "true" to set the `white-list` property.
+
+!!! tip "Changing user API provider"
+
+    The usernames provided for whitelist and ops processing are resolved using either [PlayerDB](https://playerdb.co/) or [Mojang's API](https://wiki.vg/Mojang_API#Username_to_UUID). The default uses PlayerDB, but can be changed by setting the environment variable `USER_API_PROVIDER` to "mojang". Sometimes one or the other service can become overloaded, which is why there is the ability to switch providers.
+
+
+### Op/Administrator Players
+
+Similar to the whitelist, users can be provisioned as operators (aka administrators) to your Minecraft server by
+
+- Providing a list of usernames and/or UUIDs separated by commas or newlines via the `OPS` environment variable
+- Providing the URL or container path to an ops file via `OPS_FILE` that will be retrieved/copied into the standard location
+
+!!! example
+
+    In a compose file, a text block can be used to improve maintainability, such as
+
+    ```yaml
+          OPS: |
+            user1
+            user2
+            user3
+    ```
+
+To change the behavior when the ops file already exists, set the variable `EXISTING_OPS_FILE` to one of the following options:
+
+`SKIP`
+: Skip processing of the ops file when one is already present. This is the same as setting the legacy variable `OVERRIDE_OPS` to "false".
+
+`SYNCHRONIZE`
+: Synchronize the list of users in the file with the `OPS` or `OPS_FILE` provided. When using both, `OPS` will take precedence. The `level` and `bypassesPlayerLimit` will be retained from previous entries. This is the same as setting the legacy variable `OVERRIDE_OPS` to "true".
+
+`MERGE`
+: Merge the list of users from `OPS` into the existing file. `OPS_FILE` cannot be used with this option.
+
+`SYNC_FILE_MERGE_LIST` (default)
+: When `OPS_FILE` is provided it will overwrite an existing ops file. Also, if `OPS` is provided, then those users will be merged into the newly copied file.
+
+!!! note
+
+    For versions prior to 1.7.3, `ops.txt` will be maintained instead. Only usernames are supported for those versions.
+
+### Enable/disable initial selection of datapacks
+
+New to [22W42A](https://www.minecraft.net/en-us/article/minecraft-snapshot-22w42a), datapacks with feature flags can be controlled before initial world creation by setting these to a comma separated list of packs:
+
+- `INITIAL_ENABLED_PACKS`
+  such as "update_1_20,bundle"
+- `INITIAL_DISABLED_PACKS`
+
+### Server icon
+
+A server icon can be configured by setting the `ICON` variable to a URL to download or a container path. The image will be automatically downloaded (if a URL), scaled, and converted from any other image format:
+
+!!! example
+
+    Using `docker run`:
+    
+    ```
+    docker run -d -e ICON=http://..../some/image.png ...
+    ```
+    
+    In compose file:
+    
+    ```yaml
+    environment:
+      ICON: http://..../some/image.png
+    ```
+    
+    Using a file from host filesystem:
+    
+    ```yaml
+    environment:
+      ICON: /icon.png
+      OVERRIDE_ICON: true
+    volumes:
+      ./icon.png:/icon.png
+    ```
+
+By default an existing `server-icon.png` file will not be replaced, that can be changed by setting `OVERRIDE_ICON` to "true".
+
+### RCON
+
+RCON is **enabled by default** to allow for graceful shut down of the server and coordination of save state during backups. RCON can be disabled by setting `ENABLE_RCON` to "false".
+
+!!! warning
+
+    Disabling RCON will remove and limit some features, such as interactive and color console support.
+
+#### RCON Password
+
+The default password is randomly generated on each startup. However, you can specify a password using one of the following environment variables:
+
+* Set `RCON_PASSWORD` to your desired password.
+* Set `RCON_PASSWORD_FILE` to the path of a file containing the password.
+
+Using `RCON_PASSWORD_FILE` is the recommended method for managing sensitive data, as it allows full support for [Docker Secrets](https://docs.docker.com/compose/how-tos/use-secrets/).
+
+??? example
+    ```yaml title="compose.yaml"
+    services:
+      mc:
+        image: itzg/minecraft-server:latest
+        pull_policy: daily
+        tty: true
+        stdin_open: true
+        ports:
+          - "25565:25565"
+        environment:
+          EULA: "TRUE"
+          RCON_PASSWORD_FILE: /run/secrets/rcon_pass # Points to the path where the secret is mounted
+        volumes:
+          # attach the relative directory 'data' to the container's /data path
+          - ./data:/data
+        secrets:
+          - rcon_pass
+    
+    secrets:
+      rcon_pass:
+        file: ./rcon_password # local file containing the password
+    ```
+!!! warning
+    **BE CAUTIOUS OF MAPPING THE RCON PORT EXTERNALLY** unless you are aware of all the consequences and have set a **secure password**.
+
+!!! info 
+
+    Mapping ports (`-p` command line or `ports` in compose) outside the container and docker networking needs to be a purposeful choice. Most production Docker deployments do not need any of the Minecraft ports mapped externally from the server itself.
+
+By default, the server listens for RCON on port 25575 within the container. It can be changed with `RCON_PORT` but only do this if you have a very good reason. **DO NOT change `rcon.port` via `server.properties`** or integrations will break.
+
+### Query
+
+Set the environment variable `ENABLE_QUERY` to "true" to enable the gamespy query protocol. Maps to the server property [enable-query](https://minecraft.wiki/w/Server.properties#enable-query). By default, the query port will be `25565` (UDP) but can be changed with the `QUERY_PORT` environment variable.
+
+### Level Seed
+
+If you want to create the Minecraft level with a specific seed, set the environment variable `SEED`, which maps to the [level-seed](https://minecraft.wiki/w/Server.properties#level-seed) property.
+
+If using a negative value for the seed, make sure to quote the value such as:
+
+!!! example "Using docker run"
+
+    ``` 
+    -e SEED="-1785852800490497919"
+    ```
+
+!!! example "Using compose"
+
+    ```yaml
+    environment:
+      SEED: "-1785852800490497919"
+    ```
+
+### Game Mode
+
+By default, Minecraft servers are configured to run in Survival mode. You can
+change the mode using `MODE` where you can either provide the [standard
+numerical values](http://minecraft.wiki/Game_mode#Game_modes) or the
+shortcut values:
+
+- creative
+- survival
+- adventure
+- spectator (only for Minecraft 1.8 or later)
+
+For example:
+
+    docker run -d -e MODE=creative ...
+
+### Level Type and Generator Settings
+
+By default, a standard world is generated with hills, valleys, water, etc. A different level type can
+be configured by setting `LEVEL_TYPE` to [an expected type listed here](https://minecraft.wiki/w/Server.properties#level-type).
+
+For some of the level types, `GENERATOR_SETTINGS` can be used to further customize the world generation.
+
+To configure the `GENERATOR_SETTINGS` you need to add the appropriate `GeneratorOptions` JSON configuration. In the case of a superflat world, you may omit the `flat_world_options`.
+
+The layers are applied from -64 and up and are added in the order of the list
+
+Example for a superflat world:
+
+- 1x bedrock
+- 2x stone
+- 15x sandstone
+- Desert biome
+
+```yaml
+environment:
+  LEVEL_TYPE: FLAT
+  GENERATOR_SETTINGS: >-
+      {
+          "layers": [
+              {
+                  "block": "minecraft:bedrock",
+                  "height": 1
+              },
+              {
+                  "block": "minecraft:stone",
+                  "height": 2
+              },
+              {
+                  "block": "minecraft:sandstone",
+                  "height": 15
+              }
+          ],
+          "biome": "minecraft:desert"
+      }
+```
+For more details, refer to the Minecraft Wiki sections for [Superflat Multiplayer](https://minecraft.wiki/w/Superflat#Multiplayer) and [generator options tag format](https://minecraft.wiki/w/Java_Edition_level_format#generatorOptions_tag_format).
+
+### Custom Server Resource Pack
+
+You can set a link to a custom resource pack and set it's checksum using the `RESOURCE_PACK` and `RESOURCE_PACK_SHA1` options respectively, the default is blank:
+
+    docker run -d -e 'RESOURCE_PACK=http://link.com/to/pack.zip?=1' -e 'RESOURCE_PACK_SHA1=d5db29cd03a2ed055086cef9c31c252b4587d6d0'
+
+You can enforce the resource pack on clients by setting `RESOURCE_PACK_ENFORCE` to `TRUE` (default: `FALSE`).
+
+### Level / World Save Name
+
+You can either switch between world saves or run multiple containers with different saves by using the `LEVEL` option,
+where the default is "world":
+
+    docker run -d -e LEVEL=bonus ...
+
+> **NOTE:** if running multiple containers be sure to either specify a different `-v` host directory for each
+`LEVEL` in use or don't use `-v` and the container's filesystem will keep things encapsulated.
+
+> **INFO** Refer to the [data directory](../data-directory.md) section for a visual description of where the `$LEVEL` directory is situated.
+
+### Server port
+
+> **WARNING:** only change this value if you know what you're doing. It only needs to be changed when using host-networking and it is rare that host networking should be used. Use `-p` port mappings instead.
+
+If you must, the server port can be set like:
+
+!!! example "Using docker run"
+
+    ```
+    docker run -d -e SERVER_PORT=25566 ...
+    ```
+
+!!! example "Using compose"
+
+    ```yaml
+    environment:
+      SERVER_PORT: 25566
+    ```
+
+**however**, be sure to change your port mapping accordingly and be prepared for some features to break.
+
+### Custom server properties
+
+Some mods/plugins utilize custom `server.properties` entries which can be declared via the `CUSTOM_SERVER_PROPERTIES` environment variable. The contents must be newline delimited `name=value` pairs.
+
+Within a compose file, newline delimited entries can be declared as shown here:
+
+```yaml
+      CUSTOM_SERVER_PROPERTIES: |
+        custom1=value1
+        defaultworldgenerator-port=f8c04631-f744-11ec-b260-f02f74b094e0
+```
+
+When using `docker run` from a bash shell, the entries must be quoted with the `$'` syntax, such as
+
+```
+-e CUSTOM_SERVER_PROPERTIES=$'k1=v1\nk2=v2'
+```
+
+### Other server property mappings

+Everything the container manages is located under the **container's** `/data` path, as shown here:
+
+![](img/level-vs-world.drawio.png)
+
+!!! note
+
+    The container path `/data` is pre-declared as a volume, so if you do nothing then it will be allocated as an anonymous volume. As such, it is subject to removal when the container is removed. 
+
+### Attaching data directory to host filesystem
+
+In most cases the easiest way to persist and work with the minecraft data files is to use [bind mounts](https://docs.docker.com/storage/bind-mounts/) with the `-v` argument to map a directory on your host machine to the container's `/data` directory. In the following example, the path `/home/user/minecraft-data` **must be** a directory on your host machine:
+
+    -v /home/user/minecraft-data:/data
+       ------------------------- -----
+        |                         |
+        |                         +-- must always be /data
+        |
+        +-- replace with a directory on your host machine
+
+When attached in this way you can stop the server, edit the configuration under your attached directory and start the server again to pick up the new configuration.
+
+!!! important "Rootless, Podman, SELinux, AppArmor usage"
+    When running rootless containers, such as with Podman, or using SELinux / AppArmor on your system, append ":Z" to the volume mapping. For example:
+
+    ```
+    /home/user/minecraft-data:/data:Z
+    ```
+
+    There might be a safer/better way to accommodate these systems. Please post an issue or PR if you have more information.
+    
+With Docker Compose, setting up a host attached directory is even easier since relative paths can be configured. For example, with the following `compose.yaml` Docker will automatically create/attach the relative directory `minecraft-data` to the container.
+
+```yaml title="compose.yaml"
+
+services:
+  mc:
+    image: itzg/minecraft-server:latest
+    pull_policy: daily
+    ports:
+      - 25565:25565
+    environment:
+      EULA: "TRUE"
+    tty: true
+    stdin_open: true
+    restart: unless-stopped
+    volumes:
+      # attach a directory relative to the directory containing this compose file
+      - ./minecraft-data:/data
+```
+
+### Converting anonymous `/data` volume to named volume
+
+If you had used the commands in the first section, without the `-v` volume attachment, then an anonymous data volume was created by Docker. You can later bring over that content to a named or host attached volume using the following procedure.
+
+!!! note 
+
+    In this example, it is assumed the original container was given a `--name` of "mc", so change the container identifier accordingly.
+    
+    You can also locate the Docker-managed directory from the `Source` field obtained from `docker inspect <container id or name> -f "{{json .Mounts}}"`
+
+First, stop the existing container:
+
+``` shell
+docker stop mc
+```
+
+Use a temporary container to copy over the anonymous volume's content into a named volume, "mc" in this case:
+
+``` shell
+docker run --rm --volumes-from mc -v mc:/new alpine cp -avT /data /new
+```
+
+Now you can recreate the container with any environment variable changes, etc by attaching the named volume created from the previous step:
+
+``` shell
+docker run -d -it --name mc-new -v mc:/data -p 25565:25565 -e EULA=TRUE -e MEMORY=2G itzg/minecraft-server
+```
+
+### Locating filesystem path of anonymous volume
+
+The `Source` field from the output of this command will show where the anonymous volume is mounted from:
+
+``` shell
+docker inspect -f "{{json .Mounts}}" CONTAINER_NAME_OR_ID
+```
+
+!!! note
+
+    On Windows with WSL the volumes path is `\\wsl$\docker-desktop-data\data\docker\volumes`

+
+This docker image provides a Minecraft Server that will automatically download the latest stable
+version at startup. You can also run/upgrade to any specific version or the
+latest snapshot. See the _Versions_ section below for more information.
+
+To simply use the latest stable version, run
+
+    docker run -d -it -p 25565:25565 -e EULA=TRUE itzg/minecraft-server
+
+where, in this case, the standard server port 25565 will be exposed on your host machine.
+
+!!! important "Persistent Data"
+
+    The Minecraft server will store its data in the container's `/data` directory. This directory can be [mounted](https://docs.docker.com/storage/volumes/) from the host machine or a managed volume.
+
+    Using `docker run` add a `-v` option somewhere before the image name:
+    
+    ```
+    ... -v /path/on/host:/data itzg/minecraft-server
+    ```
+    
+    Using docker compose, add a `volumes` section to the service definition:
+    
+    ```yaml
+    services:
+      mc:
+        # ... image and environment section
+        volumes:
+          # attach the relative directory 'data' to the container's /data path
+          - ./data:data
+    ```
+
+!!! note
+
+    If you plan on running a server for a longer amount of time it is highly recommended using a management layer such as [Docker Compose](#using-docker-compose) or [Kubernetes](misc/deployment/index.md#on-kubernetes) to allow for incremental reconfiguration and image upgrades.
+
+!!! info 
+
+    Be sure to always include `-e EULA=TRUE` in your commands and container definitions, as Mojang/Microsoft requires EULA acceptance.
+
+By default, the container will download the latest version of the "vanilla" [Minecraft: Java Edition server](https://www.minecraft.net/en-us/download/server) provided by Mojang. The [`VERSION`](versions/minecraft.md) and the [`TYPE`](types-and-platforms/index.md) can be configured to create many variations of desired Minecraft server. 
+
+## Using [Docker Compose](https://docs.docker.com/compose/)
+
+1. Create a new directory
+2. Put the contents of the file below in a file called `compose.yaml`
+3. Run `docker compose up -d` in that directory
+4. Done! Point your client at your host's name/IP address and port 25565.
+
+```yaml title="compose.yaml"
+
+services:
+  mc:
+    image: itzg/minecraft-server:latest
+    pull_policy: daily
+    tty: true
+    stdin_open: true
+    ports:
+      - "25565:25565"
+    environment:
+      EULA: "TRUE"
+    volumes:
+      # attach the relative directory 'data' to the container's /data path
+      - ./data:/data
+```
+
+To apply changes made to the compose file, just run `docker compose up -d` again.
+
+Follow the logs of the container using `docker compose logs -f`, check on the status with `docker compose ps`, and stop the container using `docker compose stop`.
+
+!!! note "Configurator Tool"
+    If you prefer to use an interactive tool to create or edit a Docker Compose file for this image, you can check out [setupmc.com's configurator](https://setupmc.com/java-server/). It provides a form that supports most of the image variables and generates the `compose.yaml` file in real time.
+
+!!! note "More Compose Examples"
+    There are more [examples located in the Github repo](https://github.com/itzg/docker-minecraft-server/tree/master/examples).
+
+!!! note "Deployment Examples"
+    The [deployments page](misc/deployment/index.md) provides more examples of deployment with and beyond Docker Compose.

+# Auto-Pause
+
+!!! important
+
+    As of [1.21.2](https://minecraft.wiki/w/Java_Edition_1.21.2) it is not recommend to use this feature since Minecraft server natively auto-pauses when the server is empty. That is configured via the enivironment variable `PAUSE_WHEN_EMPTY_SECONDS`, which maps to the `pause-when-empty-seconds` server property. 
+
+An auto-pause functionality is provided that monitors whether clients are connected to the server. If a client is not connected for a specified time, the Java process is put into a pause state. When a client attempts to connect while the process is paused, then process will be restored to a running state. The experience for the client does not change. This feature can be enabled by setting the environment variable `ENABLE_AUTOPAUSE` to "true".
+
+!!! important
+
+**You must greatly increase or disable max-tick-time watchdog functionality.** From the server's point of view, the pausing causes a single tick to take as long as the process is stopped, so the server watchdog might intervene after the process is continued, possibly forcing a container restart. To prevent this, ensure that the `max-tick-time` in the `server.properties` file is set to a very large value or -1 to disable it entirely, which is highly recommended. That can be set with `MAX_TICK_TIME` as described in [server properties](../../configuration/server-properties.md).
+
+    Non-vanilla versions might have their own configuration file, you might have to disable their watchdogs separately. For PaperMC servers, you need to send the JVM flag `-Ddisable.watchdog=true`, this can be done with the docker env variable `-e JVM_DD_OPTS=disable.watchdog:true`
+
+    On startup the `server.properties` file is checked and, if applicable, a warning is printed to the terminal. When the server is created (no data available in the persistent directory), the properties file is created with the Watchdog disabled.
+
+The utility used to wake the server (`knock(d)`) works at network interface level. So the correct interface has to be set using the `AUTOPAUSE_KNOCK_INTERFACE` variable when using non-default networking environments (e.g. host-networking, Portainer oder NAS solutions). See the description of the variable below.
+
+A file called `.paused` is created in `/data` directory when the server is paused and removed when the server is resumed. Other services may check for this file's existence before waking the server.
+
+A `.skip-pause` file can be created in the `/data` directory to make the server skip autopausing, for as long as the file is present. The autopause timer will also be reset.
+
+A starting, example compose file has been provided in [the examples](https://github.com/itzg/docker-minecraft-server/blob/master/examples/autopause/compose.yml).
+
+!!! note 
+
+    When configuring kubernetes readiness/liveness health checks with auto-pause enabled, be sure to reference the `mc-health` wrapper script rather than `mc-status` directly.
+
+## Additional configuration
+
+The following environment variables define the behaviour of auto-pausing:
+
+- `AUTOPAUSE_TIMEOUT_EST`, default `3600` (seconds)
+  describes the time between the last client disconnect and the pausing of the process (read as timeout established)
+- `AUTOPAUSE_TIMEOUT_INIT`, default `600` (seconds)
+  describes the time between server start and the pausing of the process, when no client connects inbetween (read as timeout initialized)
+- `AUTOPAUSE_TIMEOUT_KN`, default `120` (seconds)
+  describes the time between knocking of the port (e.g. by the main menu ping) and the pausing of the process, when no client connects inbetween (read as timeout knocked)
+- `AUTOPAUSE_PERIOD`, default `10` (seconds)
+  describes period of the daemonized state machine, that handles the pausing of the process (resuming is done independently)
+- `AUTOPAUSE_KNOCK_INTERFACE`, default `eth0`
+  <br>Describes the interface passed to the `knockd` daemon. If the default interface does not work, run the `ifconfig` command inside the container and derive the interface receiving the incoming connection from its output. The passed interface must exist inside the container. Using the loopback interface (`lo`) does likely not yield the desired results.
+- `AUTOPAUSE_STATUS_RETRY_LIMIT`, default 10
+- `AUTOPAUSE_STATUS_RETRY_INTERVAL`, default 2s
+
+!!! tip
+
+    To troubleshoot, add `DEBUG_AUTOPAUSE=true` to see additional output
+
+## Rootless Auto-Pause
+
+If you're running the container as rootless, then it is necessary to add the `CAP_NET_RAW` capability to the container, such as using [the `cap_add` service field](https://docs.docker.com/compose/compose-file/05-services/#cap_add) in a compose file or [`--cap-add` docker run argument](https://docs.docker.com/engine/reference/run/#runtime-privilege-and-linux-capabilities). It may also be necessary to set the environment variable `SKIP_SUDO` to "true". 
+
+You might need to set change the default port forwarder from RootlessKit to slirp4netns.
+
+For Docker, see the following for setup:
+
+- https://docs.docker.com/engine/security/rootless/#networking-errors
+- https://rootlesscontaine.rs/getting-started/docker/#changing-the-port-forwarder
+
+For Podman, see the following for setup:
+- https://rootlesscontaine.rs/getting-started/podman/#changing-the-port-forwarder

+# Auto-Stop
+
+An option to stop the server after a specified time has been added for niche applications (e.g. billing saving on AWS Fargate). The function is incompatible with the Autopause functionality, as they basically cancel out each other.
+
+!!! note
+
+    the docker container variables have to be set accordingly (restart policy set to "no") and that the container has to be manually restarted.
+
+A `.skip-stop` file can be created in the `/data` directory to make the server skip autostopping, for as long as the file is present. The autostop timer will also be reset.
+
+A starting, example compose file has been provided in [examples/docker-compose-autostop.yml](https://github.com/itzg/docker-minecraft-server/blob/master/examples/docker-compose-autostop.yml).

+Enable the Autostop functionality by setting:
+
+```

+
+!!! tip "For advanced use only"
+
+    This page describes a capability that is not applicable to most users. It is only intended for rare cases when a very specific Java base image is needed or additional packages need to be installed that are not generally applicable or would bloat the image size.
+
+    Be sure to confirm that the desired [version and variant of Java isn't already provided](../versions/java.md).
+
+## Building image locally with alternate Java base
+
+An alternate Java base image can be specified by setting the [docker build argument](https://docs.docker.com/reference/cli/docker/buildx/build/#build-arg) `BASE_IMAGE` to the desired base image. The following shows an example of using the base image `ghcr.io/graalvm/graalvm-ce:ol8-java11`:
+
+```shell
+docker build --build-arg BASE_IMAGE=ghcr.io/graalvm/graalvm-ce:ol8-java11 -t IMG_PREFIX/minecraft-server:java11-graalvm .
+```
+
+## Building a multi-architecture image
+
+Ensure buildx/BuildKit support is enabled and run the following to build multi-architecture and push to the repository as named by the image:
+
+```shell
+docker buildx build --platform=linux/arm64 --platform=linux/arm/v7 --platform=linux/amd64 --tag IMG_PREFIX/minecraft-server --push .
+```
+
+To build for local images, multi-architecture is not supported, use the following with buildx to load the image into the local daemon:
+
+```shell
+docker buildx build --tag IMG_PREFIX/minecraft-server --load .
+```
+
+or just a plain build
+
+```shell
+docker build -t IMG_PREFIX/minecraft-server .
+```
+
+## Installing extra packages
+
+The following build args can be set to install additional packages for the respective base image distro:
+
+- `EXTRA_DEB_PACKAGES`
+- `EXTRA_DNF_PACKAGES`
+- `EXTRA_ALPINE_PACKAGES`

+## Adding a server type
+
+Adding a new server `TYPE` can vary due to the complexity of obtaining and configuring each type; however, the addition of any server type includes at least the following steps:
+
+1. Copy an existing "start-deploy*" script, such as [start-deployFabric](https://github.com/itzg/docker-minecraft-server/blob/master/scripts/start-deployFabric) and rename it accordingly making sure to retain the "start-deploy" prefix
+2. Modify the type-specific behavior between the "start-utils" preamble and the hand-off to `start-setupWorld` at the end of the script 
+3. Develop and test the changes using the [iterative process described below](#iterative-script-development)
+4. Add a case-entry to the `case "${TYPE^^}"` in [start-configuration](https://github.com/itzg/docker-minecraft-server/blob/master/scripts/start-configuration)
+5. Add a section to the [docs](https://github.com/itzg/docker-minecraft-server/tree/master/docs). It is recommended to copy-modify an existing section to retain a similar wording and level of detail
+6. [Submit a pull request](https://github.com/itzg/docker-minecraft-server/pulls)
+
+## Iterative script development
+
+Individual scripts can be iteratively developed, debugged, and tested using the following procedure.
+
+First, build a baseline of the image to include the packages needed by existing or new scripts:
+
+PowerShell: (Example of building and testing ForgeAPI)
+```powershell
+$env:FOLDER_TO_TEST="forgeapimods_projectids"
+$env:IMAGE_TO_TEST="mc-dev"
+docker build -t $env:IMAGE_TO_TEST .
+pushd "tests/setuponlytests/$env:FOLDER_TO_TEST/"
+docker compose run mc
+docker compose down -v --remove-orphans
+popd
+```
+
+PowerShell: Building different images of Java for testing
+```powershell
+$env:BASE_IMAGE='eclipse-temurin:8u312-b07-jre'
+$env:IMAGE_TO_TEST="mc-dev"
+docker build --build-arg BASE_IMAGE=$env:BASE_IMAGE -t $env:IMAGE_TO_TEST .
+```
+
+Bash: (Example of building and testing ForgeAPI)
+```bash
+export FOLDER_TO_TEST="forgeapimods_file"
+export IMAGE_TO_TEST="mc-dev"
+docker build -t $IMAGE_TO_TEST .
+pushd tests/setuponlytests/$FOLDER_TO_TEST/
+docker compose run mc
+docker compose down -v --remove-orphans
+popd
+```
+
+Using the baseline image, an interactive container can be started to iteratively run the scripts to be developed. By attaching the current workspace directory, you can use the local editor of your choice to iteratively modify scripts while using the container to run them.
+
+```shell
+docker run -it --rm -v ${PWD}:/image/scripts --entrypoint bash mc-dev
+```
+
+From within the container you can run individual scripts via the attached `/image/scripts/` path; however, be sure to set any environment variables expected by the scripts by either `export`ing them manually:
+
+```shell
+export VERSION=1.12.2
+/image/scripts/start-deployFabric
+```
+
+...or pre-pending script execution:
+
+```shell
+VERSION=1.12.2 /image/scripts/start-deployFabric
+```
+
+!!! note
+
+    You may want to temporarily add an `exit` statement near the end of your script to isolate execution to just the script you're developing.
+
+## Using development copy of tools
+
+In the cloned repo, such as [`mc-image-helper`](https://github.com/itzg/mc-image-helper), install the distribution locally by running:
+
+```shell
+./gradlew installDist
+```
+
+The distribution will be installed in the project's `build/install/mc-image-helper`. Obtain the absolute path to that directory use in the next step.
+
+Refer to the instructions above to mount any locally modified image scripts or build a local copy of the image using or with alternate `BASE_IMAGE`, as described above:
+
+```shell
+docker build -t itzg/minecraft-server .
+```
+
+Mount the local mc-image-helper distribution directory as a volume in the container at the path `/usr/share/mc-image-helper`, such as
+
+```shell
+docker run -it --rm \
+  -v /path/to/mc-image-helper/build/install/mc-image-helper:/usr/share/mc-image-helper \
+  -e EULA=true \
+  itzg/minecraft-server
+```
+
+In a compose file, include the volume mount in the `volumes` section of the container definition:
+
+```yaml
+services:
+  mc:
+    # ... usual container definition
+    volumes:
+      - /path/to/mc-image-helper/build/install/mc-image-helper:/usr/share/mc-image-helper:ro
+```
+
+For Go base tools, run
+
+```shell
+goreleaser release --snapshot --clean
+```
+
+Clone [itzg/github-releases-proxy](https://github.com/itzg/github-releases-proxy) and run it according to the instructions shown there.
+
+In the Docker build, configure the following 
+
+```shell
+--build-arg GITHUB_BASEURL=http://host.docker.internal:8080 \
+--build-arg APPS_REV=1
+```
+
+and declare one or more version overrides, such as
+
+```
+--build-arg MC_HELPER_VERSION=1.8.1-SNAPSHOT
+```
+
+## Generating release notes
+
+The following git command can be used to provide the bulk of release notes content:
+
+```shell script
+git log --invert-grep --grep "^ci:" --grep "^misc:" --grep "^docs:" --pretty="* %s" 1.1.0..1.2.0
+```

+## Healthcheck
+
+This image contains [mc-monitor](https://github.com/itzg/mc-monitor) and uses its `status` command to continually check on the container's. That can be observed from the `STATUS` column of `docker ps`
+
+```
+CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                    PORTS                                 NAMES

+```
+
+You can also query the container's health in a script-friendly way:
+
+``` shell
+> docker container inspect -f "{{.State.Health.Status}}" mc
+healthy
+```
+
+There's actually a wrapper script called `mc-health` that takes care of calling `mc-monitor status` with the correct arguments. If needing to customize the health checks parameters, such as in a Compose file, then use something like the following in the service declaration:
+
+``` yaml
+healthcheck:
+  test: mc-health
+  start_period: 1m
+  interval: 5s
+  retries: 20
+```
+
+Some orchestration systems, such as Portainer, don't allow for disabling the default `HEALTHCHECK` declared by this image. In those cases you can approximate the disabling of health checks by setting the environment variable `DISABLE_HEALTHCHECK` to `true`.
+
+The [health check in a Compose service declaration](https://docs.docker.com/reference/compose-file/services/#healthcheck) can also be disabled using:
+
+```yaml
+    healthcheck:
+      disable: true
+      test: ["NONE"]
+```
+
+### Health checks for older versions
+
+This container disables health checks for Minecraft versions before b1.8 as those versions do not support any kind of server pinging. For more information see [Server List Ping](https://minecraft.wiki/w/Java_Edition_protocol/Server_List_Ping#Beta_1.8_to_1.3).

+## Downloadable world
+
+Instead of mounting the `/data` volume, you can instead specify the URL of a ZIP or compressed TAR file containing an archived world. It will be searched for a file `level.dat` and the containing subdirectory moved to the directory named by `$LEVEL`. This means that most of the archived Minecraft worlds downloadable from the Internet will already be in the correct format.
+
+    docker run -d -e WORLD=http://www.example.com/worlds/MySave.zip ...
+
+!!! note
+
+    This URL must be accessible from inside the container. Therefore, you should use an IP address or a globally resolvable FQDN, or else the name of a linked container.
+
+!!! note
+
+    If the archive contains more than one `level.dat`, then the one to select can be picked with `WORLD_INDEX`, which defaults to 1.
+
+## Cloning world from a container path
+
+The `WORLD` option can also be used to reference a directory, zip file, or compressed tar file that will be used as a source to clone or extract the world directory.
+
+For example, the following would initially clone the world's content from `/worlds/basic`. Also notice in the example that you should use a read-only volume attachment to ensure the clone source remains pristine.
+
+```
+docker run ... -v $HOME/worlds:/worlds:ro -e WORLD=/worlds/basic
+```
+
+The following diagram shows how this option can be used in a compose deployment with a relative directory:
+
+![](../img/world-copy-compose-project.drawio.png)
+
+## Overwrite world on start
+The world will only be downloaded or copied if it doesn't exist already. Set `FORCE_WORLD_COPY=TRUE` to force overwrite the world on every server start.
+
+## Custom worlds directory path
+To set a custom worlds directory for the Multiverse plugin on a baremetal server, you'd pass the `--world-dir` argument after the jar file.
+In order to accomplish the same in a containerized server, set the `EXTRA_ARGS` environment variable in your command line or docker compose yaml to the same argument string. For example:
+
+```
+docker run -d -e EXTRA_ARGS='--world-dir ./worlds/'
+```
+`--world-container`, `-W`, and `--universe` are aliases to `--world-dir` and can also be used.
+
+## Datapacks
+
+Datapacks can be installed in a similar manner to mods/plugins. There are many environment variables which function in the same way they do for [mods](../mods-and-plugins/index.md):
+
+* `DATAPACKS`: comma-separated list of zip file URL, zip file in container, or directory in container
+* `DATAPACKS_FILE`: a text file within the container where each line is a zip file URL, zip file in container, or directory in container
+* `REMOVE_OLD_DATAPACKS`: if "true" the datapacks directory is removed of everything matching `REMOVE_OLD_DATAPACKS_INCLUDE`, but excluding `REMOVE_OLD_DATAPACKS_EXCLUDE` no deeper than `REMOVE_OLD_DATAPACKS_DEPTH`
+* `REMOVE_OLD_DATAPACKS_DEPTH`: default is 16
+* `REMOVE_OLD_DATAPACKS_INCLUDE`: default is `*.zip`
+* `REMOVE_OLD_DATAPACKS_EXCLUDE`: default is empty
+
+Datapacks will be placed in `/data/$LEVEL/datapacks`
+
+## VanillaTweaks
+
+[VanillaTweaks](https://vanillatweaks.net/) datapacks, crafting tweaks, and resource packs can be installed with a share code from the website **OR** a json file to specify packs to download and install. Datapacks and crafting tweaks will be installed into the current world directory specified by `$LEVEL`. As new versions of the packs are retrieved the previous versions will automatically be cleaned up.
+
+The share code is the part following the hash sign, as shown here:
+
+```
+https://vanillatweaks.net/share/#MGr52E
+                                 ------

+                                  +- share code MGr52E
+```
+
+Accepted Parameters:
+
+- `VANILLATWEAKS_FILE`: comma separated list of JSON VanillaTweak pack files accessible within the container
+- `VANILLATWEAKS_SHARECODE`: comma separated list of share codes
+
+Example of expected VanillaTweaks share codes:
+
+!!! note
+
+    ResourcePacks, DataPacks, and CraftingTweaks all have separate sharecodes
+
+``` yaml
+VANILLATWEAKS_SHARECODE: MGr52E,tF1zL2,LnEDwT

+# Auto-download from CurseForge
+
+Mods and plugins can be auto-downloaded and upgraded from CurseForge by setting `CURSEFORGE_FILES` to a comma or space delimited list of [project-file references](#project-file-references). References removed from the declaration are automatically cleaned up and setting `CURSEFORGE_FILES` to an empty string removes all previously managed project-files.
+
+A specific file can be omitted from each reference to allow for auto-selecting the newest version of the selected mod/plugin. The resolved `VERSION` and `TYPE` will be taken into consideration for selecting the appropriate file. 
+
+!!! warning "CurseForge API key usage"
+
+    A CurseForge API key must be allocated and set with `CF_API_KEY` (or `CF_API_KEY_FILE`) [as described here](../types-and-platforms/mod-platforms/auto-curseforge.md#api-key).
+
+## Project-file references
+
+!!! tip
+
+    Individual project files typically represent a version of the mod/plugin, but CurseForge refers to these items broadly as "files" rather than "versions". 
+
+The following formats are supported in the list of project-file references:
+
+- A project page URL, such as `https://www.curseforge.com/minecraft/mc-mods/jei`. _The newest applicable file will be automatically selected._
+- A file page URL, such as `https://www.curseforge.com/minecraft/mc-mods/jei/files/4593548`
+- Project slug, such as `jei`. _The newest applicable file will be automatically selected._
+- Project ID, such as `238222`. _The newest applicable file will be automatically selected._
+- Project slug or ID, `:`, and a file ID, such as `jei:4593548` or `238222:4593548`
+- Project slug or ID, `@`, and a partial filename, such as `jei@10.2.1.1005`. This option is useful to refer to a version of the mod/plugin rather than looking up the file ID.
+- An `@` followed by the **container path** to a listing file
+
+!!! info "More about listing files"
+
+    Each line in the listing file is processed as one of the references above; however, blank lines and comments that start with `#` are ignored.
+    
+    Make sure to place the listing file in a mounted directory/volume or declare an appropriate mount for it.
+    
+    For example, `CURSEFORGE_FILES` can be set to "@/extras/cf-mods.txt", assuming "/extras" has been added to `volumes` section, where the container file `/extras/cf-mods.txt` contains
+    
+    ```text
+    # This comment is ignored
+    jei:10.2.1.1005
+    
+    # This and previous blank line are ignore
+    geckolib
+    aquaculture
+    naturalist
+    ```
+
+!!! tip "Multi-line values in Docker Compose"
+
+    Making use of the space delimited option, compose file declarations can be organized nicely with a [multi-line string](https://yaml-multiline.info/), such as
+    
+    ```yaml
+          CURSEFORGE_FILES: |
+            geckolib
+            aquaculture
+            naturalist
+    ```
+
+## Dependencies
+
+The files processing can detect if a dependency is missing from the given list, but is not able to resolve the dependencies otherwise since their metadata only gives the mod ID and not the specific file version/ID that is needed.

+# Working with mods and plugins
+
+## Modpack platforms
+
+By far the easiest way to work with mod and plugins, especially large numbers of them, is to utilize modpacks with [one of the supported modpack platforms](../types-and-platforms/index.md).
+
+The following are some supported modpack platforms:
+
+- [Modrinth](../types-and-platforms/mod-platforms/modrinth-modpacks.md) 
+- [CurseForge](../types-and-platforms/mod-platforms/auto-curseforge.md)
+- [Feed the Beast](../types-and-platforms/mod-platforms/ftb.md)
+
+## Download automation
+
+On the left, there are sections describing some download automation options.
+
+## Mods vs Plugins
+
+The terms "mods" and "plugins" can be quite confusing. Generally, the rule of thumb is that "mods" are used by the types that run client side to modify rendering, add new blocks, and add behaviors server, such as [Forge](../types-and-platforms/server-types/forge.md) and [Fabric](../types-and-platforms/server-types/fabric.md). "Plugins" are used by the types that **only run on servers** to add behaviors, commands, etc such as [Paper](../types-and-platforms/server-types/paper.md) (which derives from [Bukkit/Spigot](../types-and-platforms/server-types/bukkit-spigot.md)). There are also some types that are [hybrids](../types-and-platforms/server-types/hybrids.md), such as Magma, that use both "mods" and "plugins".
+
+Typically, mods needs to be installed in both the client and server; however, there are some cases when only the server needs a mod. Plugins only need to be installed in the server and are never needed in the client.
+
+## Optional plugins, mods, and config attach points
+
+There are optional volume paths that can be attached to supply content to be copied into the data area:
+
+`/plugins`
+: content in this directory is synchronized into `/data/plugins` for server types that use plugins, [as described above](#mods-vs-plugins). For special cases, the source can be changed by setting `COPY_PLUGINS_SRC` and destination by setting `COPY_PLUGINS_DEST`. If using a mod-based loader, such as Forge or Fabric, but a hybrid mod like [Cardboard](https://modrinth.com/mod/cardboard), then set `USES_PLUGINS` to have the automation utilize `/plugins` mount.
+
+!!! example "Using Cardboard plugins with Fabric"
+
+    ```yaml
+        environment:
+          EULA: "TRUE"
+          TYPE: "FABRIC"
+          MODRINTH_PROJECTS: |
+            fabric-api
+            cardboard
+          USES_PLUGINS: true
+    ```
+
+`/mods`
+: content in this directory is synchronized into `/data/mods` for server types that use mods, [as described above](#mods-vs-plugins). For special cases, the source can be changed by setting `COPY_MODS_SRC` and destination by setting `COPY_MODS_DEST`.
+
+`/config`
+: contents are synchronized into `/data/config` by default, but can be changed with `COPY_CONFIG_DEST`. For example, `-v ./config:/config -e COPY_CONFIG_DEST=/data` will allow you to copy over files like `bukkit.yml` and so on directly into the server directory. The source can be changed by setting `COPY_CONFIG_SRC`. Set `SYNC_SKIP_NEWER_IN_DESTINATION=false` if you want files from `/config` to take precedence over newer files in `/data/config`.
+
+By default, the [environment variable processing](../configuration/interpolating.md) is performed on synchronized files that match the expected suffixes in `REPLACE_ENV_SUFFIXES` (by default "yml,yaml,txt,cfg,conf,properties,hjson,json,tml,toml") and are not excluded by `REPLACE_ENV_VARIABLES_EXCLUDES` and `REPLACE_ENV_VARIABLES_EXCLUDE_PATHS`. This processing can be disabled by setting `REPLACE_ENV_DURING_SYNC` to `false`.
+
+If you want old mods/plugins to be removed before the content is brought over from those attach points, then add `-e REMOVE_OLD_MODS=TRUE`. You can fine tune the removal process by specifying the `REMOVE_OLD_MODS_INCLUDE` and `REMOVE_OLD_MODS_EXCLUDE` variables, which are comma separated lists of file glob patterns. If a directory is excluded, then it and all of its contents are excluded. By default, only jars are removed. 
+
+You can also specify the `REMOVE_OLD_MODS_DEPTH` (default is 16) variable to only delete files up to a certain level.
+
+For example: `-e REMOVE_OLD_MODS=TRUE -e REMOVE_OLD_MODS_INCLUDE="*.jar" -e REMOVE_OLD_MODS_DEPTH=1` will remove all old jar files that are directly inside the `plugins/` or `mods/` directory.
+
+These paths work well if you want to have a common set of modules in a separate location, but still have multiple worlds with different server requirements in either persistent volumes or a downloadable archive.
+
+!!! information "Multiple source directories"
+
+    `COPY_PLUGINS_SRC`, `COPY_MODS_SRC`, `COPY_CONFIG_SRC` can each be set to a comma or newline delimited list of container directories to reference.
+
+    For example, in a compose file:
+    
+    ```yaml
+        environment:
+          # ...EULA, etc
+          TYPE: PAPER
+          # matches up to volumes declared below
+          COPY_PLUGINS_SRC: /plugins-common,/plugins-local
+        volumes:
+          - mc-data:/data
+          # For example, reference a shared directory used by several projects
+          - ../plugins-common:/plugins-common:ro
+          # and add plugins unique to this project
+          - ./plugins:/plugins-local:ro
+    ```
+
+    Alternatively, you can declare other directories along with files and URLs to use in [the `MODS` / `PLUGINS` variables](#modsplugins-list).
+
+## Applying extra configuration files
+
+You can download/copy additional configuration files or other resources before the server starts by using the `APPLY_EXTRA_FILES` environment variable. This is useful for downloading configs that you want to patch or modify during the startup process.
+
+The format uses a `<` separator between the destination path and the source URL/path. The destination path is relative to the `/data` directory. If specifying a source path, it needs to be path mounted within the container.
+
+!!! example
+
+    With `docker run`
+    
+    ```
+    -e APPLY_EXTRA_FILES=destination<source_url[,destination2<source_url2,...]
+    ```
+    
+    With a compose file:
+    ```yaml
+    environment:
+      APPLY_EXTRA_FILES: |
+        destination<source1_url
+        destination2<source2_path
+    ```
+
+!!! tip "Patch-able"
+
+The `APPLY_EXTRA_FILES` feature is processed prior to [patch processing](../configuration/interpolating.md#patching-existing-files), so this can be used as for baseline files to be patched further at runtime.
+
+## Zip file modpack
+
+Like the `WORLD` option above, you can specify the URL or container path of a "mod pack" to download and install into `mods` for Forge/Fabric or `plugins` for Bukkit/Spigot. To use this option pass the environment variable `MODPACK`, such as
+
+```shell
+docker run -d -e MODPACK=http://www.example.com/mods/modpack.zip ...
+```
+
+!!! note
+    The referenced URL/file must be a zip file with one or more jar files at the
+    top level of the zip archive. Make sure the jars are compatible with the
+    particular `TYPE` of server you are running.
+
+## Generic pack files
+
+To install all the server content (jars, mods, plugins, configs, etc.) from a zip or tgz file, then set `GENERIC_PACK` to the container path or URL of the archive file. This can also be used to apply a CurseForge modpack that is missing a server start script and/or Forge installer.
+
+If multiple generic packs need to be applied together, set `GENERIC_PACKS` instead, with a comma separated list of archive file paths and/or URLs to files.
+
+To avoid repetition, each entry will be prefixed by the value of `GENERIC_PACKS_PREFIX` and suffixed by the value of `GENERIC_PACKS_SUFFIX`, both of which are optional. For example, the following variables
+
+```
+GENERIC_PACKS=configs-v9.0.1,mods-v4.3.6
+GENERIC_PACKS_PREFIX=https://cdn.example.org/
+GENERIC_PACKS_SUFFIX=.zip
+```
+
+would expand to `https://cdn.example.org/configs-v9.0.1.zip,https://cdn.example.org/mods-v4.3.6.zip`.
+
+If applying large generic packs, the update can be time-consuming. To skip the update set `SKIP_GENERIC_PACK_UPDATE_CHECK` to "true". Conversely, the generic pack(s) can be forced to be applied by setting `FORCE_GENERIC_PACK_UPDATE` to "true".
+
+The most time-consuming portion of the generic pack update is generating and comparing the SHA1 checksum. To skip the checksum generation, set `SKIP_GENERIC_PACK_CHECKSUM` to "true".
+
+To disable specific mods, which can be useful for conflicts between multiple generic packs, you can use the `GENERIC_PACKS_DISABLE_MODS` variable to specify mods to disable.
+
+Disabling mods with docker run:
+```shell
+docker run -d -e GENERIC_PACKS_DISABLE_MODS="mod1.jar mod2.jar" ...
+```
+
+Disabling mods within docker compose files:
+```yaml
+      GENERIC_PACKS_DISABLE_MODS: |
+        mod1.jar
+        mod2.jar
+```
+
+## Mods/plugins list
+
+You may also download or copy over individual mods/plugins using the `MODS` or `PLUGINS` environment variables. Both are a comma or newline delimited list of
+
+- URL of a jar file
+- container path to a jar file
+- container path to a directory containing jar files
+
+```shell
+docker run -d -e MODS=https://www.example.com/mods/mod1.jar,/plugins/common,/plugins/special/mod2.jar ...
+```
+
+The newline delimiting allows for compose file usage like:
+```yaml
+      PLUGINS: |
+        https://download.geysermc.org/v2/projects/geyser/versions/latest/builds/latest/downloads/spigot
+        https://download.geysermc.org/v2/projects/floodgate/versions/latest/builds/latest/downloads/spigot
+```
+
+!!! note "Auto-removal"
+
+    Entries that are removed from the `MODS` or `PLUGINS` list will be automatically removed from the `mods` or `plugins` directory. This is useful for removing mods/plugins that are no longer needed. An empty `MODS` or `PLUGINS` list will remove all mods/plugins.
+
+!!! note "Disable processing"
+
+    To temporarily disable processing of the `MODS` or `PLUGINS` list, then comment out the `MODS` or `PLUGINS` environment variable.
+
+## Mod/Plugin URL Listing File 
+
+As an alternative to `MODS`/`PLUGINS`, the variable `MODS_FILE` or `PLUGINS_FILE` can be set with the container path or URL of a text file listing a mod/plugin URLs on each line. For example, the following
+
+     -e MODS_FILE=/extras/mods.txt
+
+would load from a file mounted into the container at `/extras/mods.txt`. That file might look like:
+
+```text
+https://edge.forgecdn.net/files/2965/233/Bookshelf-1.15.2-5.6.40.jar
+https://edge.forgecdn.net/files/2926/27/ProgressiveBosses-2.1.5-mc1.15.2.jar
+# This and next line are ignored
+#https://edge.forgecdn.net/files/3248/905/goblintraders-1.3.1-1.15.2.jar
+https://edge.forgecdn.net/files/3272/32/jei-1.15.2-6.0.3.16.jar
+https://edge.forgecdn.net/files/2871/647/ToastControl-1.15.2-3.0.1.jar
+```
+
+!!! note
+
+    Blank lines and lines that start with a `#` will be ignored
+
+    [This compose file](https://github.com/itzg/docker-minecraft-server/blob/master/examples/mods-file/docker-compose.yml) shows another example of using this feature.
+
+## Remove old mods/plugins
+
+When the `MODPACK` option above is specified you can also instruct script to delete old mods/plugins prior to installing new ones. This behaviour is desirable in case you want to upgrade mods/plugins from downloaded zip file.
+
+To use this option pass the environment variable `REMOVE_OLD_MODS=TRUE`, such as
+
+```shell
+docker run -d -e REMOVE_OLD_MODS=TRUE -e MODPACK=http://www.example.com/mods/modpack.zip ...
+```
+
+!!! danger 
+
+    All content of the `mods` or `plugins` directory will be deleted before unpacking new content from the MODPACK or MODS.

+# Auto-download from Modrinth
+
+[Modrinth](https://modrinth.com/) is an open source modding platform with a clean, easy to use website for finding [Fabric, Forge, etc mods](https://modrinth.com/mods) and [Paper, etc plugins](https://modrinth.com/plugins), and [datapacks](https://modrinth.com/datapacks). At startup, the container will automatically locate and download the newest versions of mod/plugin files that correspond to the `TYPE` and `VERSION` in use. Older file versions downloaded previously will automatically be cleaned up.
+
+## Usage
+
+To use this feature, set the environment variable `MODRINTH_PROJECTS` to a comma or newline separated list of projects.  
+
+Each project entry can be any of the following combinations where a colon (`:`) is used to separate the different parts:
+
+```
+         Project
+         Project : Version
+         Project : Release Type
+Prefix : Project
+Prefix : Project : Version
+Prefix : Project : Release Type
+@ Listing File
+```
+
+Where:
+
+- **Project** is the project slug or ID, see below
+- **Version** is the version ID (such as "Oa9ZDzZq") or number (such as "2.21.2"). When omitted, the latest release version will be selected. Using version ID will override Minecraft and loader compatibility checks.
+- **Release Type** is `release`, `beta`, or `alpha` indicating the latest version to select.
+- **Prefix** is `datapack`, `fabric`, `forge`, or `paper`
+    - The `datapack` prefix is optional when running a vanilla server
+    - The `fabric`, `forge`, and `paper` prefixes allow for installing mods/plugins that differ from server's `TYPE`. Using [Sinytra Connector](https://modrinth.com/mod/connector) is an example of this, where Fabric mods can be loaded into a NeoForge server.
+- **Listing file** is a container path to a file containing a list of projects
+
+!!! tip "Project ID"
+
+    The project ID can be copied to the clipboard from the project page menu:
+
+    ![Modrinth copy project ID](../img/modrinth-copy-project-id.png)
+
+!!! tip "Project Slug"
+
+    The project slug is the part of the URL that follows `/mod/`, `/plugin/`, or `/datapack/`. For example, this one is "essentialsx".
+
+    ![](../img/modrinth-plugin-project-slug.png)
+
+!!! tip "Version number and ID"
+
+    The version number and ID are located in the metadata panel on a version specific page, such as <https://modrinth.com/plugin/essentialsx/version/2.21.2>
+
+    ![Version ID](../img/modrinth-version-id.drawio.png)

+### Notes
+
+!!! info "More about listing files"
+
+    Each line in the listing file is processed as one of the references above; however, blank lines and comments that start with `#` are ignored.
+    
+    Make sure to place the listing file in a mounted directory/volume or declare an appropriate mount for it.
+    
+    For example, `MODRINTH_PROJECTS` can be set to "@/extras/modrinth-mods.txt", assuming "/extras" has been added to `volumes` section, where the container file `/extras/modrinth-mods.txt` contains
+    
+    ```text
+    # This comment is ignored
+    fabric-api
+    
+    # This and previous blank line are ignore
+    cloth-config
+    datapack:terralith
+    ```
+
+!!! note "Auto-removal"
+
+    Entries that are removed from the `MODRINTH_PROJECTS` list will be automatically removed from the `mods` or `plugins` directory. This is useful for removing mods/plugins that are no longer needed. An empty `MODRINTH_PROJECTS` list will remove all mods/plugins.
+
+!!! note "Disable processing"
+
+    To temporarily disable processing of the `MODRINTH_PROJECTS` list, then comment out the `MODRINTH_PROJECTS` environment variable.
+
+## Version from Projects
+
+When the environment variable `VERSION_FROM_MODRINTH_PROJECTS` is set to "true" the Minecraft [`VERSION`](../versions/minecraft.md) will be automatically determined by looking at the most recent version of Minecraft that is supported by all the projects provided in `MODRINTH_PROJECTS`.
+
+!!! example
+
+    Given the environment variables
+    
+    ```yaml
+        MODRINTH_PROJECTS: |
+          viaversion
+          viabackwards
+          griefprevention
+          discordsrv
+        VERSION_FROM_MODRINTH_PROJECTS: true
+    ```
+    
+    Let's say all are supported on Minecraft up to 1.21.8 except griefprevention, which is only supported up to 1.21.7. In that case, `VERSION` will be automatically set to 1.21.7.
+
+## Extra options
+
+`MODRINTH_DOWNLOAD_DEPENDENCIES`
+: Can be set to `none` (the default), `required`, or `optional` to download required and/or optional dependencies.
+
+`MODRINTH_PROJECTS_DEFAULT_VERSION_TYPE`
+: The version type is used to determine the newest version to use from each project. The allowed values are `release` (default), `beta`, `alpha`. Setting to `beta` will pick up both release and beta versions. Setting to `alpha` will pick up release, beta, and alpha versions.
+
+`MODRINTH_LOADER`
+: When using a custom server, set this to specify which loader type will be requested during lookups

+# Packwiz Modpacks
+
+[packwiz](https://packwiz.infra.link/) is a CLI tool for maintaining and providing modpack definitions, with support for both CurseForge and Modrinth as sources. See the [packwiz tutorial](https://packwiz.infra.link/tutorials/getting-started/) for more information.
+
+To configure server mods using a packwiz modpack, set the `PACKWIZ_URL` environment variable to the location of your `pack.toml` modpack definition:
+
+```
+docker run -d --pull=always \
+    -v /path/on/host:/data -e TYPE=FABRIC \
+    -e "PACKWIZ_URL=https://example.com/modpack/pack.toml" \
+    itzg/minecraft-server
+```
+
+packwiz modpack definitions are processed before other mod definitions (`MODPACK`, `MODS`, etc.) to allow for additional processing/overrides you may want to perform (in case of mods not available via Modrinth/CurseForge, or you do not maintain the pack).
+
+!!! note 
+
+    packwiz is pre-configured to only download server mods. If client-side mods are downloaded and cause issues, check your pack.toml configuration, and make sure any client-only mods are not set to `"both"`, but rather `"client"` for the side configuration item.

+
+The `SPIGET_RESOURCES` variable can be set with a comma-separated list of SpigotMC resource IDs to automatically download [Spigot/Bukkit/Paper plugins](https://www.spigotmc.org/resources/) using [the spiget API](https://spiget.org/). Resources that are zip files will be expanded into the plugins directory and resources that are simply jar files will be moved there.
+
+!!! important "SPIGET not SPIGOT"
+    The variable is purposely spelled SPIG**E**T with an "E"

+                                                 =====
+
+For example, the following will auto-download the [LuckPerms](https://www.spigotmc.org/resources/luckperms.28140/) and [Vault](https://www.spigotmc.org/resources/vault.34315/) plugins:
+
+    -e SPIGET_RESOURCES=28140,34315
+
+!!! note
+    Some plugins, such as EssentialsX (resource ID 9089), do not permit automated downloads via Spiget. Instead, you will need to pre-download the desired file and supply it to the container, such as using the `/plugins` mount point, described [in the main section](index.md).

+# Server Types and Modpack Platforms
+
+Server types can be selected by setting the `TYPE` environment variable to one of the types described in these sections.
+
+The default server type is [the official software provided by Mojang](https://www.minecraft.net/en-us/download/server), which can be explicitly selected by setting `TYPE` to "VANILLA".
+
+**From the sections to the left...**
+
+The **modpack platforms** take a modpack identifier, file, etc and use that to select and download the appropriate version of a mod loader, such as Forge or Fabric, downloading declared mods/plugins, and apply any additional files. The modpack platforms are selected by setting `MODPACK_PLATFORM`; however, for ease of use and backward compatibility, the selection can be set in `TYPE` or `MOD_PLATFORM`.
+
+The individual **server types** allow for selecting the mod loader / server type and specific versions of those. 
+
+!!! important
+    For all the server types, the `VERSION` environment variable is used to declare the Minecraft version itself, such as 1.19.4. Each server type will have specific variables for qualifying their version in addition to the Minecraft version.

+# Auto CurseForge
+
+To manage a CurseForge modpack automatically with upgrade support, pinned or latest version tracking, set `MODPACK_PLATFORM`, `MOD_PLATFORM` or `TYPE` to "AUTO_CURSEFORGE". The appropriate mod loader (Forge / Fabric) version will be automatically installed as declared by the modpack. This mode will also take care of cleaning up unused files installed by previous versions of the modpack, but world data is never auto-removed.
+
+## API Key
+
+!!! warning "CurseForge API key usage"
+
+    A CurseForge API key is **required** to use this feature. Go to their [developer console](https://console.curseforge.com/), generate an API key, and set the environment variable `CF_API_KEY`.
+
+    When entering your API Key in a docker compose file you will need to escape any `$` character with a second `$`. Refer to [this compose file reference section](https://docs.docker.com/compose/compose-file/compose-file-v3/#variable-substitution) for more information.
+
+    Example if your key is `$11$22$33aaaaaaaaaaaaaaaaaaaaaaaaaa`:
+    ```yaml title="compose.yaml"
+    environment:
+      CF_API_KEY: '$$11$$22$$33aaaaaaaaaaaaaaaaaaaaaaaaaa'
+    ```
+    If you use `docker run` you will need to make sure to use single quotes:
+
+    ```shell
+    docker run ... -e CF_API_KEY='$11$22$33aaaaaaaaaaaaaaaaaaaaaaaaaa'
+    ```
+
+    To avoid exposing the API key, it is highly recommended to use a `.env` file, which is [loaded automatically by docker compose](https://docs.docker.com/compose/environment-variables/set-environment-variables/#substitute-with-an-env-file). You **do not** need to escape `$`'s with a second `$` in the `.env` file **as long as the key is wrapped in single quotes**.
+
+    ```title=".env"
+    CF_API_KEY='$11$22$33aaaaaaaaaaaaaaaaaaaaaaaaaa'
+    ```
+
+    The variable should to be referenced from the compose file, such as:
+
+    ```yaml title="compose.yaml"
+    environment:
+      CF_API_KEY: ${CF_API_KEY}
+    ```
+
+    The .env file should be placed in the same directory as your compose file like so:
+
+    ```
+    minecraft-server/
+    ├── .env
+    ├── compose.yaml
+    ├── data/
+    ```
+
+    To use the equivalent with `docker run` you need to specify the `.env` file explicitly:
+    ```shell
+    docker run --env-file=.env itzg/minecraft-server
+    ```
+
+    Alternately you can use [docker secrets](https://docs.docker.com/compose/how-tos/use-secrets/) with a `CF_API_KEY_FILE` environment variable:
+    ```yaml title="compose.yaml"
+    service:
+      environment:
+        CF_API_KEY_FILE: /run/secrets/cf_api_key
+      secrets:
+        - cf_api_key
+
+    secrets:
+      cf_api_key:
+        file: cf_api_key.secret
+    ```
+
+
+!!! note
+    Be sure to use the appropriate [image tag for the Java version compatible with the modpack](../../versions/java.md).
+
+    Most modpacks require a good amount of memory, so it best to set `MEMORY` to at least "4G" since the default is only 1 GB.
+
+## Usage
+
+Use one of the following to specify the modpack to install:
+
+Pass a page URL to the modpack or a specific file with `CF_PAGE_URL` such as the modpack page "https://www.curseforge.com/minecraft/modpacks/all-the-mods-8" or a specific file "https://www.curseforge.com/minecraft/modpacks/all-the-mods-8/files/4248390".
+
+!!! example "Using CF_PAGE_URL"
+
+    ```yaml title="Using compose.yaml"
+    environment:
+      # ...
+      MODPACK_PLATFORM: AUTO_CURSEFORGE
+      # allocate from https://console.curseforge.com/ and set in .env file
+      CF_API_KEY: ${CF_API_KEY}
+      CF_PAGE_URL: https://www.curseforge.com/minecraft/modpacks/all-the-mods-8
+    ```
+
+    ```title="Using docker run"
+    docker run -e CF_API_KEY=${CF_API_KEY} -e TYPE=AUTO_CURSEFORGE -e CF_PAGE_URL=https://www.curseforge.com/minecraft/modpacks/all-the-mods-8
+    ```
+
+Instead of a URL, the modpack slug can be provided as `CF_SLUG`. The slug is the short identifier visible in the URL after "/modpacks/", such as
+
+![cf-slug](../../img/cf-slug.png)
+
+!!! example "Using CF_SLUG"
+
+    ```yaml title="Using compose.yaml"
+    environment:
+      # ...
+      MODPACK_PLATFORM: AUTO_CURSEFORGE
+      # allocate from https://console.curseforge.com/ and set in .env file
+      CF_API_KEY: ${CF_API_KEY}
+      CF_SLUG: all-the-mods-8
+    ```
+
+    ```title="Using docker run"
+    docker run -e CF_API_KEY=${CF_API_KEY} -e TYPE=AUTO_CURSEFORGE -e CF_SLUG=all-the-mods-8
+    ```
+
+### Pinning modpack and mod loader versions
+
+The latest modpack file and its associated mod loader will be located and installed by default on startup (including automatic upgrading of both on subsequent startups, if a later version is found on CurseForge). If a specific version is desired instead, you can use one of the following options. With any of these options **do not select a server file** -- they lack the required manifest and defeat the ability to consistently automate startup.
+
+- Use `CF_PAGE_URL`, but include the full URL to a specific file
+- Set `CF_FILE_ID` to the numerical file ID
+- Specify a substring to match the desired filename with `CF_FILENAME_MATCHER`
+
+The following shows where to get the URL to the specific file and also shows where the file ID is located:
+
+![cf-file-id](../../img/cf-file-id.png)
+
+The following examples all refer to version 1.0.7 of ATM8:
+
+```yaml
+  CF_PAGE_URL: https://www.curseforge.com/minecraft/modpacks/all-the-mods-8/files/4248390
+```
+
+```yaml
+  CF_SLUG: all-the-mods-8
+  CF_FILE_ID: "4248390"
+```
+
+```yaml
+  CF_SLUG: all-the-mods-8
+  CF_FILENAME_MATCHER: 1.0.7
+```
+
+Pinning modpack version also pins the mod loader (to the version specified by the modpack). Mod loader version cannot be pinned independently of the modpack.
+
+### Custom modloader versions
+
+By default, AUTO_CURSEFORGE will use the exact modloader version declared by the modpack. However, you can override the modloader version by setting the following environment variable:
+
+- `CF_MOD_LOADER_VERSION`: Override the mod loader version (e.g., `43.4.22`)
+
+!!! example "Override mod loader version"
+
+    ```yaml
+    environment:
+      MODPACK_PLATFORM: AUTO_CURSEFORGE
+      CF_API_KEY: ${CF_API_KEY}
+      CF_SLUG: all-the-mods-8
+      CF_MOD_LOADER_VERSION: "43.4.22"
+    ```
+
+    ```title="Using docker run"
+    docker run -e CF_MOD_LOADER_VERSION=43.4.22 -e CF_SLUG=my-fabric-pack ...
+    ```
+
+!!! warning "Compatibility"
+
+    Using a custom modloader version that differs significantly from what the modpack was designed for may cause compatibility issues. Use this feature carefully and test thoroughly.
+
+## Manual Downloads
+
+For mod, modpacks, and world files that are not allowed for automated download, the container path `/downloads` can be attached and matching files will be retrieved from there. The subdirectories `mods`, `modpacks`, and `worlds` will also be checked accordingly. To change the source location of downloaded files, set `CF_DOWNLOADS_REPO` to an existing container path. To disable this feature, set `CF_DOWNLOADS_REPO` to an empty string.
+
+!!! warning "Download using a browser"
+
+    It's important to use a browser to download the files listed for manual download. If your Docker host is running without a graphical interface, then you can use `scp` or similar to transfer the files to it.
+
+!!! example
+
+    Assuming Docker compose is being used:
+
+    1. Create a directory next to the `compose.yaml` file. The name doesn't matter, but "downloads" is the common convention
+    2. From the "Mods Need Download" output, visit the download page of each, click on the file download and save that file into the directory created in the previous step
+    3. Add a host directory mount to the volumes section where the container path **must be** `/downloads`. The snippet below shows how that will look
+    4. Re-run `docker compose up -d` to apply the changes
+
+    ```yaml
+        volumes:
+          ./downloads:/downloads
+    ```
+
+## Unpublished Modpacks
+
+If you wish to use an unpublished modpack zip, set the container path to the file in `CF_MODPACK_ZIP`. Similarly, the container path to a modpack manifest JSON can be passed to `CF_MODPACK_MANIFEST`.  In either case, **the modpack slug or page URL must still be provided**.
+
+!!! example
+
+    ```yaml
+    services:
+      mc:
+        image: itzg/minecraft-server:latest
+        pull_policy: daily
+        environment:
+          EULA: true
+          MODPACK_PLATFORM: AUTO_CURSEFORGE
+          # allocate from https://console.curseforge.com/ and set in .env file
+          CF_API_KEY: ${CF_API_KEY}
+          CF_MODPACK_MANIFEST: /manifests/manifest.json
+          CF_SLUG: "custom"
+        volumes:
+          - ./manifests:/manifests:ro
+    ```
+
+    where an exported manifest file should look like:
+
+    ```json
+    {
+      "minecraft": {
+        "version": "1.20.4",
+        "modLoaders": [
+          {
+            "id": "fabric-0.15.3",
+            "primary": true
+          }
+        ]
+      },
+      "manifestType": "minecraftModpack",
+      "manifestVersion": 1,
+      "name": "Custom",
+      "author": "",
+      "files": [

+          "projectID": 306612,
+          "fileID": 5010374,
+          "required": true
+        }
+      ],
+      "overrides": "overrides"
+    }
+    ```
+
+## Exclude client mods
+
+Quite often there are mods that need to be excluded, such as ones that did not properly declare as a client mod via the file's game versions. Similarly, there are some mods that are incorrectly tagged as client only. The following describes some options to exclude/include mods:
+
+Mods can be excluded by passing a comma or space delimited list of **project** slugs or IDs via `CF_EXCLUDE_MODS`. Similarly, there are some mods that are incorrectly tagged as client only. For those, pass the **project** slugs or IDs via `CF_FORCE_INCLUDE_MODS`. These lists will be combined with the content of the exclude/include file, if given. Alternatively, all mods can be excluded by setting `CF_EXCLUDE_ALL_MODS` to `true`
+
+!!! note
+    `CF_FORCE_INCLUDE_MODS` will not download additional mods.
+
+    For additional mods, refer to [the `CURSEFORGE_FILES` variable](../../mods-and-plugins/curseforge-files.md).
+
+A mod's project ID can be obtained from the right hand side of the project page:
+![cf-project-id](../../img/cf-project-id.png)
+
+For more complex scenarios, global and per modpack exclusions can be declared in a container-accessible JSON file and referenced with `CF_EXCLUDE_INCLUDE_FILE`. By default, [the file bundled with the image](https://raw.githubusercontent.com/itzg/docker-minecraft-server/master/files/cf-exclude-include.json) will be used, but can be disabled by setting this to an empty string. The schema of this file [is documented here](https://github.com/itzg/mc-image-helper#excludeinclude-file-schema).
+
+If needing to iterate on the options above, set `CF_FORCE_SYNCHRONIZE` to "true" to ensure the exclude/includes are re-evaluated.
+
+!!! important
+    These options are provided to empower you to get your server up and running quickly. Please help out by reporting an issue with the respective mod project. Ideally mod developers should [use correct registrations for one-sided client mods](https://docs.minecraftforge.net/en/latest/concepts/sides/#writing-one-sided-mods). Understandably, those code changes may be non-trivial, so mod authors can also add "Client" to the game versions when publishing.
+
+!!! tip "Embedded comments"
+
+    Comments can be embedded in the list using the `#` character.
+
+    ```yaml
+          CF_EXCLUDE_MODS: |
+            # Exclude client-side mods not published correctly
+            creative-core
+            default-options
+    ```
+
+## Excluding Overrides Files
+
+Modpack zip files typically include an `overrides` subdirectory that may contain config files, world data, and extra mod files. All of those files will be extracted into the `/data` path of the container. If any of those files, such as incompatible mods, need to be excluded from extraction, then the `CF_OVERRIDES_EXCLUSIONS` variable can be set with a comma or newline delimited list of ant-style paths ([see below](#ant-style-paths)) to exclude, relative to the overrides (or `/data`) directory.
+
+### Ant-style paths
+
+Ant-style paths can include the following globbing/wildcard symbols:
+
+| Symbol | Behavior                                                |
+|--------|---------------------------------------------------------|
+| `*`    | Matches zero, one, or many characters except a slash    |
+| `**`   | Matches zero, one, or many characters including slashes |
+| `?`    | Matches one character                                   |
+
+!!! example
+
+    The following compose `environment` entries show how to exclude Iris and Sodium mods from the overrides
+
+    ```yaml
+      CF_OVERRIDES_EXCLUSIONS: mods/iris*.jar,mods/sodium*.jar
+    ```
+
+    or using newline delimiter, which improves maintainability
+
+    ```yaml
+      CF_OVERRIDES_EXCLUSIONS: |
+        mods/iris*.jar
+        mods/sodium*.jar
+    ```
+
+## World/Level Data
+
+Some modpacks come with world/save data via a worlds file and/or the overrides provided with the modpack. Either approach can be selected to set the `LEVEL` to the resulting saves directory by setting `CF_SET_LEVEL_FROM` to either:
+
+- `WORLD_FILE`
+- `OVERRIDES`
+
+## Ignore missing files
+
+Some mods use temporary files from the modpack and delete them when finished. Others will patch themselves and "disable" the original mod jar, such as gregtech. In order to avoid the installer from detecting the absent file(s) and re-installing, those files can be ignored by passing a comma, newline delimited list, or a file globbing pattern to `CF_IGNORE_MISSING_FILES`.
+
+!!! hint
+
+    A warning log will indicate what files were found to be missing from the previous installation run, such as
+
+    ```
+    Re-installing due to missing files from modpack: [mods/gregtech-2.6.2-beta.jar]
+    ```
+
+!!! example
+
+    In a Compose file
+    ```yaml
+      environment:
+        CF_IGNORE_MISSING_FILES: |
+          mods/gregtech-2.6.2-beta.jar
+          mods/*.jar
+    ```
+
+
+## Extra options
+
+Other configuration available:
+
+- `CF_PARALLEL_DOWNLOADS` (default is 4): specify how many parallel mod downloads to perform
+- `CF_OVERRIDES_SKIP_EXISTING` (default is false): if set, files in the overrides that already exist in the data directory are skipped. **NOTE** world data is always skipped, if present.
+- `CF_FORCE_REINSTALL_MODLOADER` (default is false): this can be set to `true` to force the modpack's declared modloader, such as Forge, to be reinstalled. This is useful if some of the modloader's files become corrupted.

+# Manual CurseForge server packs
+
+!!! warning "Deprecated"
+
+    This mod platform type is deprecated. Please use [AUTO_CURSEFORGE](auto-curseforge.md) for new deployments.
+
+Enable this server mode by setting `MODPACK_PLATFORM`, `MOD_PLATFORM` or `TYPE` to "CURSEFORGE" along with the following specific variables.
+
+You need to specify a modpack to run, using the `CF_SERVER_MOD` environment
+variable. A CurseForge server modpack is available together with its respective
+client modpack at <https://www.curseforge.com/minecraft/modpacks> .
+
+Now you can add a `-e CF_SERVER_MOD=name_of_modpack.zip` to your command-line.
+```shell
+docker run -d --pull=always -v /path/on/host:/data -e TYPE=CURSEFORGE \
+    -e CF_SERVER_MOD=SkyFactory_4_Server_4.1.0.zip \
+    -p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
+```
+If you want to keep the pre-download modpacks separate from your data directory,
+then you can attach another volume at a path of your choosing and reference that.
+The following example uses `/modpacks` as the container path as the pre-download area:
+```shell
+docker run -d --pull=always -v /path/on/host:/data \
+    -v /path/to/modpacks:/modpacks -e TYPE=CURSEFORGE \
+    -e CF_SERVER_MOD=/modpacks/SkyFactory_4_Server_4.1.0.zip \
+    -p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
+```
+### Modpack data directory
+
+By default, CurseForge modpacks are expanded into the sub-directory `/data/FeedTheBeast` and executed from there. (The default location was chosen for legacy reasons, when Curse and FTB were maintained together.)
+
+The directory can be changed by setting `CF_BASE_DIR`, such as `-e CF_BASE_DIR=/data`.
+
+### Buggy start scripts
+
+Some modpacks have buggy or overly complex start scripts. You can avoid using the bundled start script and use this image's standard server-starting logic by adding `-e USE_MODPACK_START_SCRIPT=false`.
+
+### Fixing "unable to launch forgemodloader"
+
+If your server's modpack fails to load with an error [like this](https://support.feed-the-beast.com/t/cant-start-crashlanding-server-unable-to-launch-forgemodloader/6028/2):
+
+    unable to launch forgemodloader
+
+then you apply a workaround by adding this to the run invocation:

+    -e FTB_LEGACYJAVAFIXER=true

+
+[Feed the Beast application](https://www.feed-the-beast.com/) modpacks are supported by setting `MODPACK_PLATFORM`, `MOD_PLATFORM` or `TYPE` to "FTBA"
+
+!!! note
+    The "A" at the end of "FTBA" is important. The value "FTB" used to be an alias for "CURSEFORGE".

+This mod platform type will automatically take care of downloading and installing the modpack and appropriate version of Forge, so the `VERSION` does not need to be specified.
+
+### Environment Variables:
+- `FTB_MODPACK_ID`: **required**, the numerical ID of the modpack to install. The ID can be located by [finding the modpack](https://www.feed-the-beast.com/modpack) and locating the ID in this part of the URL:

+- `FTB_MODPACK_VERSION_ID`: optional, the numerical ID of the version to install. If not specified, the latest version will be installed. The "Version ID" can be obtained by hovering over a server file entry and grabbing [this ID in the URL](../../img/ftba-version-id-popup.png).
+
+- `FTB_FORCE_REINSTALL`: if the files become inconsistent, such as when accidentally removing them, the FTB can be forced to re-run by setting this to "true"
+
+### Upgrading
+
+If a specific `FTB_MODPACK_VERSION_ID` was not specified, simply restart the container to pick up the newest modpack version. If using a specific version ID, recreate the container with the new version ID.
+
+### Example
+
+The following example runs the latest version of [FTB Presents Direwolf20 1.12](https://ftb.neptunepowered.org/pack/ftb-presents-direwolf20-1-12/):

+# Auto-setup GTNH server
+
+[GT New Horizons (GTNH)](https://www.gtnewhorizons.com/) is a Minecraft 1.7.10 modpack maintained and supported by dedicated community members! With over 10 years in development, GTNH offers a carefully balanced and immersive experience to challenge players as they climb through the 15 tiers of technology. The ultimate goal of GTNH is to build the Stargate, an interdimensional teleporter and the symbol for absolute prestige, aptitude, and determination. 
+
+As GTNH is a complex modpack with some specifics it has its own `TYPE` to simplify the deployment and update process. To use it set the environment variable `TYPE` to "GTNH". 
+
+Configuration options with defaults:
+
+- `GTNH_PACK_VERSION`=latest
+- `GTNH_DELETE_BACKUPS`=false
+- `SKIP_GTNH_UPDATE_CHECK`=false
+
+## Set Modpack version
+
+As GTNH is a Minecraft 1.7.10 modpack, when using it your minecraft version is set to 1.7.10 by default. The [modpack version](https://www.gtnewhorizons.com/downloads/) can be selected by setting `GTNH_PACK_VERSION` to `latest`, `latest-dev` or any specific version number. `latest` will automatically select the latest full release version available and deploy the server with it (Note: this will also automatically update the server on startup). `latest-dev` does the same but selects the latest version marked as beta or RC (it wont select a full release version even if a newer exist). The third (and recommended) option is setting the server to a specific version like `2.8.1` to manage updates manually.
+
+> To actively prevent an update from happening you can set the environment variable `SKIP_GTNH_UPDATE_CHECK` to true this will prevent any update check from running, but will also prevent the server install from running, so just set it after the initial setup.
+
+## Ressource requirements
+
+**Recommended Minimum:**
+
+  - 2-4 cpu cores
+  - 6GB of RAM +0.5GB per extra player (early game)
+  - 6GB of RAM +1GB per extra player (~UV tier+)
+  - 20GB+ storage. HDD is feasible, SSD is preferred
+
+For more details regarding the server setup consult the [modpack wiki](https://wiki.gtnewhorizons.com/wiki/Server_Setup).
+
+## Java Version
+
+GTNH supports java 8 and 17+ (java 17+ is always recommended for maximum performance). The server will only start when a supported version of itzg/docker-minecraft-server is used.
+
+For optimal performance choose java25 with GTNH 2.8.0 and later.
+
+## Config backups
+
+During version upgrade, the server will replace all config files to make sure all new features are setup as intended. The old config files are stored in a backup folder in the data directory, for you to use as reference for manual reapplication of your changed settings. Set the environment variable `GTNH_DELETE_BACKUPS` to true to delete all backup folders at startup. 
+
+## server.properties defaults
+
+To deliver the intended GTNH by default, when running a GTNH server, the following options are set in `server.properties`. It is recommended to leave them as is, but if you know what you are doing feel free to play around with them.
+
+- `LEVEL_TYPE=rwg`
+- `DIFFICULTY=hard`
+- `ALLOW_FLIGHT=true`
+- `ENABLE_COMMAND_BLOCK=true`
+- `MOTD=Greg Tech New Horizon <current-pack-version>`
+
+## Java args
+
+With java 17+ the server starts with `-Dfml.readTimeout=180 @java9args.txt -jar lwjgl3ify-forgePatches.jar`. 
+
+With java 8 the server stars with `-XX:+UseStringDeduplication -XX:+UseCompressedOops -XX:+UseCodeCacheFlushing -Dfml.readTimeout=180 -jar forge-1.7.10-10.13.4.1614-1.7.10-universal.jar`

+# Modrinth Modpacks
+
+[Modrinth Modpacks](https://modrinth.com/modpacks) can automatically be installed along with the required mod loader (Forge or Fabric) by setting `MODPACK_PLATFORM`, `MOD_PLATFORM` or `TYPE` to "MODRINTH". Upgrading (and downgrading) takes care of cleaning up old files and upgrading (and downgrading) the mod loader.
+
+## Modpack project
+
+The desired modpack project is specified with the `MODRINTH_MODPACK` environment variable and must be one of:
+
+- The project "slug", which is located in the URL shown here:
+
+  ![](../../img/modrinth-project-slug.drawio.png)
+
+- The project ID, which is located in the bottom of the left panel, shown here
+
+  ![](../../img/modrinth-project-id.drawio.png)
+
+- The project page URL, such as <https://modrinth.com/modpack/cobblemon-fabric>. As described below, this can further be the page URL of a modpack's version page.
+
+- A custom URL of a hosted [mrpack file](https://support.modrinth.com/en/articles/8802351-modrinth-modpack-format-mrpack)
+
+- The container path to a local [mrpack file](https://support.modrinth.com/en/articles/8802351-modrinth-modpack-format-mrpack)
+
+## Modpack version
+
+The automatic modpack version resolving can be narrowed in a few ways:
+
+The latest release or beta version, respectively, of the Modrinth modpack is selected when `VERSION` is "LATEST" or "SNAPSHOT". That can be overridden by setting `MODRINTH_MODPACK_VERSION_TYPE` to "release", "beta", or "alpha".
+
+The resolved modpack version can be narrowed by setting `VERSION` to a specific Minecraft version, such as "1.19.2".
+
+The selected version can also be narrowed to a particular mod loader by setting `MODRINTH_LOADER` to either "forge", "fabric", or "quilt".
+
+Instead of auto resolving, a specific version of modpack file can be specified by passing the version's page URL to `MODRINTH_MODPACK`, such as <https://modrinth.com/modpack/cobblemon-fabric/version/1.3.2> or by setting `MODRINTH_VERSION` to the version ID or number located in the Metadata section, as shown here
+
+![](../../img/modrinth-version-id.drawio.png)
+
+## Ignore missing files
+
+Some mods, such as [MCInstance Loader](https://modrinth.com/mod/mcinstance-loader), use temporary files from the modpack and delete them when finished. In order to avoid the installer from detecting the absent file(s) and re-installing, those files can be ignored by passing a comma, newline delimited list or, a file globbing pattern to `MODRINTH_IGNORE_MISSING_FILES`.
+
+!!! example
+
+    In a Compose file
+    ```yaml
+      environment:
+        MODRINTH_IGNORE_MISSING_FILES: |
+          config/mcinstanceloader/pack.mcinstance
+          mods/*.jar
+    ```
+
+## Excluding files
+
+To exclude client mods that are incorrectly declared by the modpack as server-compatible, set `MODRINTH_EXCLUDE_FILES` to a comma or newline delimited list of partial file names to exclude. You may need to set `MODRINTH_FORCE_SYNCHRONIZE` to "true" while iterating on a compatible set of mods to use.
+
+!!! example
+
+    In a Compose file:
+    ```yaml
+      MODRINTH_EXCLUDE_FILES: |
+        notenoughanimations
+        lambdynamiclights
+        euphoriapatcher
+    ```
+
+## Force-include files
+
+To force include client mods, set `MODRINTH_FORCE_INCLUDE_FILES` to a comma or newline delimited list of partial file names. You may need to set `MODRINTH_FORCE_SYNCHRONIZE` to "true" while iterating on a compatible set of mods to use.
+
+!!! example
+
+    In a Compose file:
+    ```yaml
+      MODRINTH_FORCE_INCLUDE_FILES: |
+        yet-another-config-lib
+    ```
+
+## Default exclude/includes
+
+The image comes with a default set of exclude/includes, maintained [in the repo files area](https://github.com/itzg/docker-minecraft-server/blob/master/files/modrinth-exclude-include.json) and uses the same [JSON schema](https://github.com/itzg/mc-image-helper?tab=readme-ov-file#excludeinclude-file-schema) as Auto CurseForge. Those defaults can be disabled by setting the env var `MODRINTH_DEFAULT_EXCLUDE_INCLUDES` to an empty string.
+
+## Excluding Overrides Files
+
+Modrinth mrpack/zip files may include an `overrides` subdirectory that contains config files, world data, and extra mod files. All of those files will be extracted into the `/data` path of the container. If any of those files, such as incompatible mods, need to be excluded from extraction, then the `MODRINTH_OVERRIDES_EXCLUSIONS` variable can be set with a comma or newline delimited list of ant-style paths ([see below](#ant-style-paths)) to exclude, relative to the overrides (or `/data`) directory.
+
+### Ant-style paths
+
+Ant-style paths can include the following globbing/wildcard symbols:
+
+| Symbol | Behavior                                                |
+|--------|---------------------------------------------------------|
+| `*`    | Matches zero, one, or many characters except a slash    |
+| `**`   | Matches zero, one, or many characters including slashes |
+| `?`    | Matches one character                                   |
+
+!!! example
+
+    The following compose `environment` entries show how to exclude Iris and Sodium mods from the overrides
+    
+    ```yaml
+      MODRINTH_OVERRIDES_EXCLUSIONS: mods/NekosEnchantedBooks-*.jar,mods/citresewn-*.jar
+    ```
+    
+    or using newline delimiter, which improves maintainability
+    
+    ```yaml
+      MODRINTH_OVERRIDES_EXCLUSIONS: |
+        mods/NekosEnchantedBooks-*.jar

+
+    Some of the `VERSION` values are not as intuitive as you would think, so make sure to click into the version entry to find the **exact** version needed for the download. For example, "1.8" is not sufficient since their download naming expects `1.8-R0.1-SNAPSHOT-latest` exactly.

+
+The overall version is specified by `VERSION`, [as described in the section above](../../versions/minecraft.md) and provides the same benefits of upgrading as new versions are released. By default, the recommended version of Forge for that Minecraft version will be selected. The latest version can be selected instead by setting the environment variable `FORGE_VERSION` to "latest". You can also choose a specific Forge version by setting `FORGE_VERSION` with that version, such as "14.23.5.2854".

+To use a pre-downloaded Forge installer, place it in a location mounted into the container and specify the container path with `FORGE_INSTALLER`. To download a Forge installer from a custom location, such as your own file repository, specify the URL with `FORGE_INSTALLER_URL`.

+In both of the cases above, there is no need for the `VERSION` or `FORGE_VERSION` variables.
+
+!!! note
+
+    If an error occurred while installing Forge, it might be possible to resolve by temporarily setting `FORGE_FORCE_REINSTALL` to "true". Be sure to remove that variable after successfully starting the server.

+Notes
+
+1. Why no arm64 for Java 17 Alpine? That is because the base images, such as [elipse-temurin](https://hub.docker.com/_/eclipse-temurin/tags?page=&page_size=&ordering=&name=17-jre-alpine) do not provide support for that. Use the Ubuntu-based images instead.
+2. Short-term variant, subject to deprecation upon next version introduction
+3. Based on the [Oracle GraalVM images](https://blogs.oracle.com/java/post/new-oracle-graalvm-container-images), which as of JDK 17, are now under the [GraalVM Free License](https://blogs.oracle.com/java/post/graalvm-free-license) incorporating what used to be known as the GraalVM Enterprise.
+4. This version of Java is [recommended for PaperMC 1.16.5](https://docs.papermc.io/paper/getting-started/#requirements)
+5. Due to these images using Oracle Linux, (which is based on Red Hat Enterprise Linux) Forge Installer will not work due to its use of zlib-ng. Use other images for initial installation and Forge version upgrade.
+
+!!! example "Example using java8"
+
+    With docker run command-line
+    
+    ```
+    docker run -it -e EULA=true itzg/minecraft-server:java8
+    ```
+    
+    or in a compose file
+    
+    ```yaml
+    services:
+      mc:
+        image: itzg/minecraft-server:java8
+    ```
+
+!!! note "Latest"
+
+    The "latest" tag shifts to include not only the latest features and bug fixes, but also the latest Java version that Mojang requires for the latest Minecraft version.
+
+!!! tip "Class File Version"
+
+    If the Minecraft startup is logging an error about a "class file version", then refer [to this table](https://javaalmanac.io/bytecode/versions/) to identify the JDK/Java version corresponding to each class file version.
+
+### Release versions
+
+Since the tags referenced above will shift as the newest image build brings in new features and bug fixes, released variants of those can also be used to pin a specific build of the image.
+
+The syntax of released image tags is:
+
+    itzg/minecraft-server:<release>-<java tag>
+
+where `java tag` still refers to the first column of the table above and `release` refers to [one of the image releases](https://github.com/itzg/docker-minecraft-server/releases).
+
+!!! example
+
+    For example, the 2024.4.0 release of the Java 17 image would be
+    
+    ```
+    itzg/minecraft-server:2024.4.0-java17
+    ```
+
+### Stable image tag
+
+The `stable` image tag combines the benefits of `latest` and [release versions](#release-versions) since it shifts to refer to the most recently released version. There is also a per-variant stable tag, formatted as `stable-{variant}`.
+
+## Version compatibilities
+
+[This section in the Minecraft wiki](https://minecraft.wiki/w/Tutorials/Update_Java#Why_update?) lists out versions of **vanilla** Minecraft versions and the corresponding Java version that is required.
+
+### Class file version 65.0
+
+If encountering a startup failure similar to the following examples, then ensure that the latest image has been re-pulled to use a Java 21. Alternatively, set the image tag specifically to `itzg/minecraft-server:java21`.
+
+> Exception in thread "ServerMain" java.lang.UnsupportedClassVersionError: org/bukkit/craftbukkit/Main has been compiled by a more recent version of the Java Runtime (class file version 65.0), this version of the Java Runtime only recognizes class file versions up to 61.0
+
+or
+
+> Error: LinkageError occurred while loading main class net.minecraft.bundler.Main
+java.lang.UnsupportedClassVersionError: net/minecraft/bundler/Main has been compiled by a more recent version of the Java Runtime (class file version 65.0), this version of the Java Runtime only recognizes class file versions up to 61.0
+
+
+### Forge versions
+
+Forge and its mods sometimes utilize non-public APIs of the JVM and as such are suspceptible to becoming broken with newer Java versions.
+
+#### Java 21
+
+Some mods even up to Minecraft 1.21 require Java 17 and will not run on the latest Java version. If you see an error like the following then be sure to explicitly use a Java 17 tagged image:
+
+```
+Caused by: org.spongepowered.asm.mixin.throwables.ClassMetadataNotFoundException: java.util.List
+	at MC-BOOTSTRAP/org.spongepowered.mixin/org.spongepowered.asm.mixin.transformer.MixinPreProcessorStandard.transformMethod(MixinPreProcessorStandard.java:754)
+```
+
+#### Java 8
+
+For Forge versions less than 1.18, you _must_ use the `java8-multiarch` (or other java8) image tag.
+
+In general, if you see the following line in a server startup failure, then it means you need to be using Java 8 instead of the latest image Java version:
+
+```
+Caused by: java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader 
+   cannot be cast to class java.net.URLClassLoader
+```
+
+Forge also doesn't support openj9 JVM implementation.
