## Auto CurseForge Management
To manage a CurseForge modpack automatically with upgrade support, pinned or latest version tracking, set `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.
> **NOTES:**
>
> 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 `$` character with a second `$`.
>
> Example if your key is `$11$22$33aaaaaaaaaaaaaaaaaaaaaaaaaa`:
> ```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$33aaaaaaaaaaaaaaaaaaaaaaaaaa'
> ```
>
> To avoid exposing the API key, it is highly recommended to use a `.env` file, which is [loaded automatically by docker compose](https://docs.docker.com/compose/environment-variables/set-environment-variables/#substitute-with-an-env-file). `$`'s in the value still need to escaped with a second `$` and the variable needs to be referenced from the compose file, such as:
> ```yaml
> environment:
> CF_API_KEY: ${CF_API_KEY}
> ```
>
> To use the equivalent with `docker run` you need to specify the `.env` file explicitly:
> ```
> docker run --env-file=.env itzg/minecraft-server
> ```
>
> 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.
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". For example:
```
-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)
For example:
```
-e TYPE=AUTO_CURSEFORGE -e CF_SLUG=all-the-mods-8
```
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.
If the authors of the modpack have disallowed project distribution, then the desired **client** modpack zip will need to be manually downloaded and made available to the container. The path to that file must be passed to `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.
The latest file will be located and used by default, but if a specific version is desired 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:
```
-e CF_PAGE_URL=https://www.curseforge.com/minecraft/modpacks/all-the-mods-8/files/4248390
```
```
-e CF_SLUG=all-the-mods-8 -e CF_FILE_ID=4248390
```
```
-e CF_SLUG=all-the-mods-8 -e CF_FILENAME_MATCHER=1.0.7
```
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 two options to exclude/include mods:
Global and per modpack exclusions can be declared in a 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).
Alternatively, they 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.
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)
If needing to iterate on the options above, set `CF_FORCE_SYNCHRONIZE` to "true" to ensure the exclude/includes are re-evaluated.
> **NOTE:** 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.
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`
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.
## Old approach
Enable this server mode by adding `-e TYPE=CURSEFORGE` to your command-line,
but note the following additional steps needed...
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.
docker run -d -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:
docker run -d -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

!!! note
Requires one of the Ubuntu with Hotspot images listed in [the Java versions section](../versions/java.md).
[Feed the Beast application](https://www.feed-the-beast.com/) modpacks are supported by using `-e TYPE=FTBA` (**note** the "A" at the end of the type). This server 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:
```
https://www.feed-the-beast.com/modpacks/23-ftb-infinity-evolved-17
^^
```
- `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).
### 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/):
``` shell
docker run -d --name mc-ftb -e EULA=TRUE \
-e TYPE=FTBA -e FTB_MODPACK_ID=31 \
-p 25565:25565 \
itzg/minecraft-server:java8-multiarch
```
!!! note
Normally you will also add `-v` volume for `/data` since the mods and config are installed there along with world data.

### 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`
: contents are synchronized into `/data/plugins` for Bukkit related server types. The source can be changed by setting `COPY_PLUGINS_SRC`. The destination can be changed by setting `COPY_PLUGINS_DEST`. Set `SYNC_SKIP_NEWER_IN_DESTINATION=false` if you want files from `/plugins` to take precedence over newer files in `/data/plugins`.
`/mods`
: contents are synchronized into `/data/mods` for Fabric and Forge related server types. The source can be changed by setting `COPY_MODS_SRC`. The destination can be changed by setting `COPY_MODS_DEST`.
`/config`
: contents are synchronized into `/data/config` by default, but can be changed with `COPY_CONFIG_DEST`. The source can be changed by setting `COPY_CONFIG_SRC`. 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. 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/misc-options.md#replacing-variables-inside-configs) 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.
> For more flexibility with mods/plugins preparation, you can declare directories to use in [the `MODS` variable](#downloadable-modplugin-pack-for-forge-fabric-and-bukkit-like-servers)
### Auto-downloading SpigotMC/Bukkit/PaperMC plugins with Spiget
The `SPIGET_RESOURCES` variable can be set with a comma-separated list of SpigotMC resource IDs to automatically download [SpigotMC resources/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.
> NOTE: the variable is purposely spelled SPIG**E**T with an "E"
The **resource ID** can be located from the numerical part of the URL after the shortname and a dot. For example, the ID is **9089** from
https://www.spigotmc.org/resources/essentialsx.9089/
====
For example, the following will auto-download the [EssentialsX](https://www.spigotmc.org/resources/essentialsx.9089/) and [Vault](https://www.spigotmc.org/resources/vault.34315/) plugins:
-e SPIGET_RESOURCES=9089,34315
### Auto-download mods from Modrinth
[Modrinth](https://modrinth.com/) is an open source modding platform with a clean, easy to use website for finding [Fabric and Forge mods](https://modrinth.com/mods). At startup, the container will automatically locate and download the newest versions of mod files that correspond to the `TYPE` and `VERSION` in use. Older file versions downloaded previously will automatically be cleaned up.
- **MODRINTH_PROJECTS** : comma separated list of project slugs (short name) or IDs. The project ID can be located in the "Technical information" section. The slug is the part of the page URL that follows `/mod/`:
```
https://modrinth.com/mod/fabric-api
----------
|
+-- project slug
```
Also, specific version/type can be declared using colon symbol and version id/type after the project slug. The version id can be found at 'Metadata' section. Valid version types are `release`, `beta`, `alpha`. For instance:
```
-e MODRINTH_PROJECTS=fabric-api,fabric-api:PbVeub96,fabric-api:beta
```
- **MODRINTH_DOWNLOAD_OPTIONAL_DEPENDENCIES**=true : required dependencies of the project will _always_ be downloaded and optional dependencies can also be downloaded by setting this to `true`
- **MODRINTH_ALLOWED_VERSION_TYPE**=release : the version type is used to determine the newest version to use from each project. The allowed values are `release`, `beta`, `alpha`.
### Downloadable mod/plugin pack for Forge, Fabric, and Bukkit-like Servers
Like the `WORLD` option above, you can specify the URL or 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
docker run -d -e MODPACK=http://www.example.com/mods/modpack.zip ...
**NOTE:** The referenced URL 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.
You may also download or copy over individual mods using the `MODS` environment variable. `MODS` contains a comma-separated list of
- URL of a jar file
- container path to a jar file
- container path to a directory containing jar files
docker run -d -e MODS=https://www.example.com/mods/mod1.jar,/plugins/common,/plugins/special/mod2.jar ...
### ForgeAPI usage to use non-version specific projects
**NOTE:** This potentially could lead to unexpected behavior if the Mod receives an update with unexpected behavior.
This is more complicated because you will be pulling/using the latest mod for the release of your game. To get started make sure you have a [CursedForge API Key](https://docs.curseforge.com/#getting-started). Then use the environmental parameters in your docker build.
Please be aware of the following when using these options for your mods:
* Mod Release types: Release, Beta, and Alpha.
* Mod dependencies: Required and Optional
* Mod family: Fabric, Forge, and Bukkit.
Parameters to use the ForgeAPI:
* `MODS_FORGEAPI_KEY` - Required
* `MODS_FORGEAPI_FILE` - Required or use MODS_FORGEAPI_PROJECTIDS (Overrides MODS_FORGEAPI_PROJECTIDS)
* `MODS_FORGEAPI_PROJECTIDS` - Required or use MODS_FORGEAPI_FILE
* `MODS_FORGEAPI_RELEASES` - Default is release, Options: [Release|Beta|Alpha]
* `MODS_FORGEAPI_DOWNLOAD_DEPENDENCIES` - Default is False, attempts to download required mods (releaseType Release) defined in Forge.
* `MODS_FORGEAPI_IGNORE_GAMETYPE` - Default is False, Allows for filtering mods on family type: FORGE, FABRIC, and BUKKIT. (Does not filter for Vanilla or custom)
* `REMOVE_OLD_FORGEAPI_MODS` - Default is False
* `REMOVE_OLD_DATAPACKS_DEPTH` - Default is 1
* `REMOVE_OLD_DATAPACKS_INCLUDE` - Default is *.jar
Example of expected forge api project ids, releases, and key:
```yaml
MODS_FORGEAPI_PROJECTIDS: 306612,256717
MODS_FORGEAPI_RELEASES: Release
MODS_FORGEAPI_KEY: $WRX...
```
Example of expected ForgeAPI file format.
**Field Description**:
* `name` is currently unused, but can be used to document each entry.
* `projectId` id is the id found on the CurseForge website for a particular mod
* `releaseType` Type corresponds to forge's R, B, A icon for each file. Default Release, options are (release|beta|alpha).
* `fileName` is used for version pinning if latest file will not work for you.
```json
[
{
"name": "fabric api",
"projectId": "306612",
"releaseType": "release"
},
{
"name": "fabric voice mod",
"projectId": "416089",
"releaseType": "beta"
},
{
"name": "Biomes o plenty",
"projectId": "220318",
"fileName": "BiomesOPlenty-1.18.1-15.0.0.100-universal.jar",
"releaseType": "release"
}
]
```
### 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.
### Mod/Plugin URL Listing File
As an alternative to `MODS`, the variable `MODS_FILE` can be set with the path to a text file listing a mod/plugin URL 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/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/docker-compose-mods-file.yml) shows another example of using this feature.
It is recommended to combine this option with `REMOVE_OLD_MODS=TRUE` to ensure the mods/plugins remain consistent with the file's listing.
### Remove old mods/plugins
When the option above is specified (`MODPACK`) 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
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.

[Modrinth Modpacks](https://modrinth.com/modpacks) can automatically be installed along with the required mod loader (Forge or Fabric) by setting `TYPE` to "MODRINTH". Upgrading (and downgrading) takes care of cleaning up old files and upgrading (and downgrading) the mod loader.
The desired modpack project is specified with the `MODRINTH_PROJECT` 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.
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_DEFAULT_VERSION_TYPE` to "release", "beta", or "alpha".
Furthermore, 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_PROJECT`, 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

[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 -v /path/on/host:/data -e TYPE=FABRIC \
-e "PACKWIZ_URL=https://example.com/modpack/pack.toml" \
itzg/minecraft-server
```
packwiz modpack defitions 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.
