 ## Healthcheck

 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 healthchecks by setting the environment variable `DISABLE_HEALTHCHECK` to `true`.
 
+## Autopause (experimental)
+
+### Description
+
+> EXPERIMENTAL: this feature only works with default bridge networking using official Docker distributions. Host networking and container management software, such as Portainer, and NAS solutions do not seem to provide compatible networking.
+
+There are various bug reports on [Mojang](https://bugs.mojang.com) about high CPU usage of servers with newer versions, even with few or no clients connected (e.g. [this one](https://bugs.mojang.com/browse/MC-149018), in fact the functionality is based on [this comment in the thread](https://bugs.mojang.com/browse/MC-149018?focusedCommentId=593606&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-593606)).
+
+An autopause functionality has been added to this image to monitor whether clients are connected to the server. If for a specified time no client is connected, the Java process is stopped. When knocking on the server port (e.g. by the ingame Multiplayer server overview), the process is resumed. The experience for the client does not change.
+
+Of course, even loaded chunks are not ticked when the process is stopped.
+
+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 correctly.
+

-In order to manage mods, you have two options:
+### Using the /data volume
 
-1. [Attach a host directory to the /data path](#attaching-data-directory-to-host-filesystem) and manage the contents of the `mods` subdirectory
+This is the easiest way if you are using a persistent `/data` mount.
 
-2. Using a mods-mount
+To do this, you will need to attach the container's `/data` directory
+(see "Attaching data directory to host filesystem”).
+Then, you can add mods to the `/path/on/host/mods` folder you chose. From the example above,
+the `/path/on/host` folder contents look like:
 
-If the container paths `/mods` and/or `/config` exist, such as by attaching a docker volume or host path, then any files in either of these directories will be copied over to the respective `/data` subdirectory before starting Minecraft. 
+```
+/path/on/host
+├── mods
+│   └── ... INSTALL MODS HERE ...
+├── config
+│   └── ... CONFIGURE MODS HERE ...
+├── ops.json
+├── server.properties
+├── whitelist.json
+├── worlds
+│   └── ... PLACE MAPS IN THEIR OWN FOLDERS HERE ...
+└── ...
+```
 
-If you want old mods to be removed as the `/mods` content is updated, 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. By default, everything will be removed. You can also specify the `REMOVE_OLD_MODS_DEPTH` (default is 16) variable to only delete files up to a certain level.
+Providing a presistent `/data` mount is a good idea, both to persist the game world and to allow for the manual configuration which is sometimes needed.
 
-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.
+For instance, imagine a scenario when the initial launch has completed, but you now want to change the worldmap for your server.  
 
-You can specify the destination of the files that are copied from `/config` by setting the `COPY_CONFIG_DEST` variable, where the default is `/data/config`. 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.
+Assuming you have a shared directory to your container, you can then (after first launch) drag and drop your premade maps or worlds into the `\worlds\` directory.  **Note:** each world should be placed in its own folder under the `\worlds\` directory.  
 
-> NOTE: If a file was updated in the destination path and is newer than the source file from `/config`, then it will not be overwritten.
+Once your maps are in the proper path, you can then specify which map the server uses by changing the `level-name` value in `server.properties` to match the name of your map.
+
+If you add mods or make changes to `server.properties` while the container is running, you'll need to restart it to pick those
+up:
+
+    docker stop mc
+    docker start mc
+
+### Using separate mounts
+
+This is the easiest way if you are using an ephemeral `/data` filesystem,
+or downloading a world with the `WORLD` option.
+
+There are two additional volumes that can be mounted; `/mods` and `/config`.
+Any files in either of these filesystems will be copied over to the main
+`/data` filesystem before starting Minecraft. If you want old mods to be removed as the `/mods` content is updated, then add `-e REMOVE_OLD_MODS=TRUE`. If you are running a `BUKKIT` distribution this will affect all files inside the `plugins/` directory. You can fine tune the removal process by specifing the `REMOVE_OLD_MODS_INCLUDE` and `REMOVE_OLD_MODS_EXCLUDE` variables. By default everything will be removed. You can also specify the `REMOVE_OLD_MODS_DEPTH` (default 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.
+
+This works 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.
+
+You can specify the destination of the configs that are located inside the `/config` mount by setting the `COPY_CONFIG_DEST` variable. The configs are copied recursivly to the `/data/config` directory by default. If a file was updated directly inside the `/data/*` directoy and is newer than the file in the `/config/*` mount it will not be overriden.
+
+> For example: `-v ./config:/config -e COPY_CONFIG_DEST=/data` will allow you to copy over your `bukkit.yml` and so on directly into the server directory.
+
+### Replacing variables inside configs
+
+Sometimes you have mods or plugins that require configuration information that is only available at runtime.
+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.
+
+If you set the enviroment variable `REPLACE_ENV_VARIABLES` to `TRUE` the startup script
+will go thru all files inside your `/data` volume and replace variables that match your
+defined environment variables. Variables that you want to replace need to be wrapped
+inside `${YOUR_VARIABLE}` curly brackets and prefixed with a dollar sign. This is the regular
+syntax for enviromment variables inside strings or config files.
+
+Optionally you can also define a prefix to only match predefined environment variables.
+
+`ENV_VARIABLE_PREFIX="CFG_"` <-- this is the default prefix
+
+If you want use file for value (like when use secrets) you can add suffix `_FILE` to your variable name (in  run command).
+
+There are some limitations to what characters you can use.
+
+| Type  | Allowed Characters  |
+| ----- | ------------------- |
+| Name  | `0-9a-zA-Z_-`       |
+| Value | `0-9a-zA-Z_-:/=?.+` |
+
+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`.

+  host: ${CFG_DB_HOST}
+  name: ${CFG_DB_NAME}

 For some cases, if e.g. after removing mods, it could be necessary to startup minecraft with an additional `-D` parameter like `-Dfml.queryResult=confirm`. To address this you can use the environment variable `JVM_DD_OPTS`, which builds the params from a given list of values separated by space, but without the `-D` prefix. To make things running under systems (e.g. Plesk), which doesn't allow `=` inside values, a `:` (colon) could be used instead. The upper example would look like this:
 `JVM_DD_OPTS=fml.queryResult:confirm`, and will be converted to `-Dfml.queryResult=confirm`.

-## Autopause
-
-### Description
-
-There are various bug reports on [Mojang](https://bugs.mojang.com) about high CPU usage of servers with newer versions, even with few or no clients connected (e.g. [this one](https://bugs.mojang.com/browse/MC-149018), in fact the functionality is based on [this comment in the thread](https://bugs.mojang.com/browse/MC-149018?focusedCommentId=593606&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-593606)).
-
-An autopause functionality has been added to this image to monitor whether clients are connected to the server. If for a specified time no client is connected, the Java process is stopped. When knocking on the server port (e.g. by the ingame Multiplayer server overview), the process is resumed. The experience for the client does not change.
-
-Of course, even loaded chunks are not ticked when the process is stopped.
-
-**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 [the section below](#max-tick-time).
-
-> **NOTE:** Non-vanilla versions might have their own configuration file, you might have to disable their watchdogs separately (e.g. PAPER Servers).
-
-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 starting, example compose file has been provided in [examples/docker-compose-autopause.yml](examples/docker-compose-autopause.yml).
-
-### Enabling Autopause
-
-Enable the Autopause functionality by setting:
-
-```
--e ENABLE_AUTOPAUSE=TRUE
-```
-
-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.

-> NOTE: you may need to lower the memory allocation, such as `-e MEMORY=750m`
-
-> If experiencing issues such as "sleep: cannot read realtime clock: Operation not permitted", ensure `libseccomp` is up to date on your host. In some cases adding `:Z` flag to the `/data` mount may be needed, [but use cautiously](https://docs.docker.com/storage/bind-mounts/#configure-the-selinux-label).
