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.
|
|
|
|
[![Click for more docs](https://i.imgur.com/jS02ebD.png)](https://github.com/itzg/docker-minecraft-server/blob/master/README.md)
|
|
|
|
To simply use the latest stable version, run
|
|
|
|
docker run -d -p 25565:25565 --name mc itzg/minecraft-server
|
|
|
|
where the standard server port, 25565, will be exposed on your host machine.
|
|
|
|
If you want to serve up multiple Minecraft servers or just use an alternate port,
|
|
change the host-side port mapping such as
|
|
|
|
docker run -p 25566:25565 ...
|
|
|
|
will serve your Minecraft server on your host's port 25566 since the `-p` syntax is
|
|
`host-port`:`container-port`.
|
|
|
|
Speaking of multiple servers, it's handy to give your containers explicit names using `--name`, such as
|
|
|
|
docker run -d -p 25565:25565 --name mc itzg/minecraft-server
|
|
|
|
With that you can easily view the logs, stop, or re-start the container:
|
|
|
|
docker logs -f mc
|
|
( Ctrl-C to exit logs action )
|
|
|
|
docker stop mc
|
|
|
|
docker start mc
|
|
|
|
## Looking for a Bedrock Dedicated Server
|
|
|
|
For Minecraft clients running on consoles, mobile, or native Windows, you'll need to
|
|
use this image instead:
|
|
|
|
[itzg/minecraft-bedrock-server](https://hub.docker.com/r/itzg/minecraft-bedrock-server)
|
|
|
|
## Interacting with the server
|
|
|
|
[RCON](http://wiki.vg/RCON) is enabled by default, so you can `exec` into the container to
|
|
access the Minecraft server console:
|
|
|
|
```
|
|
docker exec -i mc rcon-cli
|
|
```
|
|
|
|
Note: The `-i` is required for interactive use of rcon-cli.
|
|
|
|
To run a simple, one-shot command, such as stopping a Minecraft server, pass the command as
|
|
arguments to `rcon-cli`, such as:
|
|
|
|
```
|
|
docker exec mc rcon-cli stop
|
|
```
|
|
|
|
_The `-i` is not needed in this case._
|
|
|
|
In order to attach and interact with the Minecraft server, add `-it` when starting the container, such as
|
|
|
|
docker run -d -it -p 25565:25565 --name mc itzg/minecraft-server
|
|
|
|
With that you can attach and interact at any time using
|
|
|
|
docker attach mc
|
|
|
|
and then Control-p Control-q to **detach**.
|
|
|
|
For remote access, configure your Docker daemon to use a `tcp` socket (such as `-H tcp://0.0.0.0:2375`)
|
|
and attach from another machine:
|
|
|
|
docker -H $HOST:2375 attach mc
|
|
|
|
Unless you're on a home/private LAN, you should [enable TLS access](https://docs.docker.com/articles/https/).
|
|
|
|
## EULA Support
|
|
|
|
Mojang now requires accepting the [Minecraft EULA](https://account.mojang.com/documents/minecraft_eula). To accept add
|
|
|
|
-e EULA=TRUE
|
|
|
|
such as
|
|
|
|
docker run -d -it -e EULA=TRUE -p 25565:25565 --name mc itzg/minecraft-server
|
|
|
|
## Attaching data directory to host filesystem
|
|
|
|
In order to readily access the Minecraft data, use the `-v` argument
|
|
to map a directory on your host machine to the container's `/data` directory, such as:
|
|
|
|
docker run -d -v /path/on/host:/data ...
|
|
|
|
When attached in this way you can stop the server, edit the configuration under your attached `/path/on/host`
|
|
and start the server again with `docker start CONTAINERID` to pick up the new configuration.
|
|
|
|
## Versions
|
|
|
|
To use a different Minecraft version, pass the `VERSION` environment variable, which can have the value
|
|
|
|
* LATEST
|
|
* SNAPSHOT
|
|
* (or a specific version, such as "1.7.9")
|
|
|
|
For example, to use the latest snapshot:
|
|
|
|
docker run -d -e VERSION=SNAPSHOT ...
|
|
|
|
or a specific version:
|
|
|
|
docker run -d -e VERSION=1.7.9 ...
|
|
|
|
## Healthcheck
|
|
|
|
This image contains [Dinnerbone's mcstatus](https://github.com/Dinnerbone/mcstatus) and uses
|
|
its `ping` 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
|
|
b418af073764 mc "/start" 43 seconds ago Up 41 seconds (healthy) 0.0.0.0:25565->25565/tcp, 25575/tcp mc
|
|
```
|
|
|
|
You can also query the container's health in a script friendly way:
|
|
|
|
```
|
|
> docker container inspect -f "{{.State.Health.Status}}" mc
|
|
healthy
|
|
```
|
|
|
|
Finally, since `mcstatus` is on the `PATH` you can exec into the container
|
|
and use mcstatus directly and invoke any of its other commands:
|
|
|
|
```
|
|
> docker exec mc mcstatus localhost status
|
|
version: v1.12 (protocol 335)

|
|
```
|
|
|
|
## Running a Forge Server
|
|
|
|
Enable Forge server mode by adding a `-e TYPE=FORGE` to your command-line.
|
|
By default the container will run the `RECOMMENDED` version of [Forge server](http://www.minecraftforge.net/wiki/)
|
|
but you can also choose to run a specific version with `-e FORGEVERSION=10.13.4.1448`.
|
|
|
|
$ docker run -d -v /path/on/host:/data -e VERSION=1.7.10 \
|
|
-e TYPE=FORGE -e FORGEVERSION=10.13.4.1448 \
|
|
-p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
|
|
|
|
To use a pre-downloaded Forge installer, place it in the attached `/data` directory and
|
|
specify the name of the installer file with `FORGE_INSTALLER`, such as:
|
|
|
|
$ docker run -d -v /path/on/host:/data ... \
|
|
-e FORGE_INSTALLER=forge-1.11.2-13.20.0.2228-installer.jar ...
|
|
|
|
To download a Forge installer from a custom location, such as your own file repository, specify
|
|
the URL with `FORGE_INSTALLER_URL`, such as:
|
|
|
|
$ docker run -d -v /path/on/host:/data ... \
|
|
-e FORGE_INSTALLER_URL=http://HOST/forge-1.11.2-13.20.0.2228-installer.jar ...
|
|
|
|
In both of the cases above, there is no need for the `VERSION` or `FORGEVERSION` variables.
|
|
|
|
In order to add mods, you have two options.
|
|
|
|
### Using the /data volume
|
|
|
|
This is the easiest way if you are using a persistent `/data` 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:
|
|
|
|
```
|
|
/path/on/host
|
|
├── mods
|
|
│ └── ... INSTALL MODS HERE ...
|
|
├── config
|
|
│ └── ... CONFIGURE MODS HERE ...
|
|
├── ops.json
|
|
├── server.properties
|
|
├── whitelist.json
|
|
└── ...
|
|
```
|
|
|
|
If you add mods 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.
|
|
|
|
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.
|
|
|
|
### 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 enviroment variables.
|
|
|
|
`ENV_VARIABLE_PREFIX="CFG_"` <-- this is the default prefix
|
|
|
|
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`.
|
|
|
|
Here is a full example where we want to replace values inside a `database.yml`.
|
|
|
|
```yml
|
|
...
|
|
database:
|
|
host: ${CFG_DB_HOST}
|
|
name: ${CFG_DB_NAME}
|
|
password: ${CFG_DB_PASSWORD}
|
|
```
|
|
|
|
This is how your `docker-compose.yml` file could look like:
|
|
|
|
```yml
|
|
version: '3'
|
|

## Running a Bukkit/Spigot server
|
|
|
|
Enable Bukkit/Spigot server mode by adding a `-e TYPE=BUKKIT -e VERSION=1.8` or `-e TYPE=SPIGOT -e VERSION=1.8` to your command-line.
|
|
|
|
docker run -d -v /path/on/host:/data \
|
|
-e TYPE=SPIGOT -e VERSION=1.8 \
|
|
-p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
|
|
|
|
If you are hosting your own copy of Bukkit/Spigot you can override the download URLs with:
|
|
* -e BUKKIT_DOWNLOAD_URL=<url>
|
|
* -e SPIGOT_DOWNLOAD_URL=<url>
|
|
|
|
You can build spigot from source by adding `-e BUILD_FROM_SOURCE=true`
|
|
|
|
__NOTE: to avoid pegging the CPU when running Spigot,__ you will need to
|
|
pass `--noconsole` at the very end of the command line and not use `-it`. For example,
|
|
|
|
docker run -d -v /path/on/host:/data \
|
|
-e TYPE=SPIGOT -e VERSION=1.8 \
|
|
-p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server --noconsole
|
|
|
|
|
|
You can install Bukkit plugins in two ways...
|
|
|
|
### Using the /data volume
|
|
|
|
This is the easiest way if you are using a persistent `/data` 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 plugins to the `/path/on/host/plugins` folder you chose. From the example above,
|
|
the `/path/on/host` folder contents look like:
|
|
|
|
```
|
|
/path/on/host
|
|
├── plugins
|
|
│ └── ... INSTALL PLUGINS HERE ...
|
|
├── ops.json
|
|
├── server.properties
|
|
├── whitelist.json
|
|
└── ...
|
|
```
|
|
|
|
If you add plugins 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 is one additional volume that can be mounted; `/plugins`.
|
|
Any files in this filesystem will be copied over to the main
|
|
`/data/plugins` filesystem before starting Minecraft.
|
|
|
|
This works well if you want to have a common set of plugins in a separate
|
|
location, but still have multiple worlds with different server requirements
|
|
in either persistent volumes or a downloadable archive.
|
|
|
|
### Building an image with plugins
|
|
|
|
You can also create your own Docker images by extending the `itzg/minecraft-server` image.
|
|
The image contains an `ONBUILD` trigger that will copy a `plugins.yml` file from you build directory and download any plugins specified in it.
|
|
|
|
You can read about the [`ToF-BuildTools` and how to use them here](https://git.faldoria.de/tof/server/build-tools).
|
|
|
|
You can also find [an example](examples/ToF-build/) with a custom image in the examples dir.
|
|
|
|
## Running a PaperSpigot server
|
|
|
|
Enable PaperSpigot server mode by adding a `-e TYPE=PAPER -e VERSION=1.9.4` to your command-line.
|
|
|
|
docker run -d -v /path/on/host:/data \
|
|
-e TYPE=PAPER -e VERSION=1.9.4 \
|
|
-p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
|
|
|
|
__NOTE: to avoid pegging the CPU when running PaperSpigot,__ you will need to
|
|
pass `--noconsole` at the very end of the command line and not use `-it`. For example,
|
|
|
|
docker run -d -v /path/on/host:/data \
|
|
-e TYPE=PAPER -e VERSION=1.9.4 \
|
|
-p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server --noconsole
|
|
|
|
If you are hosting your own copy of PaperSpigot you can override the download URL with:
|
|
* -e PAPER_DOWNLOAD_URL=<url>
|
|
|
|
You can install Bukkit plugins in two ways...
|
|
|
|
An example compose file is provided at
|
|
[examples/docker-compose-paper.yml](examples/docker-compose-paper.yml).
|
|
|
|

|
## Running a Server with a Feed-The-Beast (FTB) / CurseForge modpack
|
|
|
|
Enable this server mode by adding a `-e TYPE=FTB` or `-e TYPE=CURSEFORGE` to your command-line,
|
|
but note the following additional steps needed...
|
|
|
|
You need to specify a modpack to run, using the `FTB_SERVER_MOD` or `CF_SERVER_MOD` environment
|
|
variable. An FTB/CurseForge server modpack is available together with its respective
|
|
client modpack on https://www.feed-the-beast.com under "Additional Files." Similar you can
|
|
locate the modpacks for CurseForge at https://minecraft.curseforge.com/modpacks .
|
|
|
|
There are a couple of options for obtaining an FTB/CurseForge modpack.
|
|
One options is that you can pre-download the **server** modpack and copy the modpack to the `/data`
|
|
directory (see "Attaching data directory to host filesystem”).
|
|
|
|
Now you can add a `-e FTB_SERVER_MOD=name_of_modpack.zip` to your command-line.
|
|
|
|
docker run -d -v /path/on/host:/data -e TYPE=FTB \
|
|
-e FTB_SERVER_MOD=FTBPresentsSkyfactory3Server_3.0.6.zip \
|
|
-p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
|
|
|
|
Instead of pre-downloading a modpack from the FTB/CurseForge site, you
|
|
can you set `FTB_SERVER_MOD` (or `CF_SERVER_MOD`) to the **server** URL of a modpack, such as
|
|
|
|
docker run ... \
|
|
-e TYPE=FTB \
|
|
-e FTB_SERVER_MOD=https://www.feed-the-beast.com/projects/ftb-infinity-lite-1-10/files/2402889
|
|
|
|
or for a CurseForce modpack:
|
|
|
|
docker run ... \
|
|
-e TYPE=CURSEFORGE \
|
|
-e CF_SERVER_MOD=https://minecraft.curseforge.com/projects/enigmatica2expert/files/2663153/download
|
|
|
|
### Using the /data volume
|
|
|
|
You must use a persistent `/data` mount for this type of server.
|
|
|
|
To do this, you will need to attach the container's `/data` directory
|
|
(see "Attaching data directory to host filesystem”).
|
|
|
|
If the modpack is updated and you want to run the new version on your
|
|
server, you stop and remove the container:
|
|
|
|
docker stop mc
|
|
docker rm mc
|
|
|
|
Do not erase anything from your /data directory (unless you know of
|
|
specific mods that have been removed from the modpack). Download the
|
|
updated FTB server modpack and copy it to `/data`. Start a new container
|
|
with `FTB_SERVER_MOD` specifying the updated modpack file.
|
|
|
|
$ docker run -d -v /path/on/host:/data -e TYPE=FTB \
|
|
-e FTB_SERVER_MOD=FTBPresentsSkyfactory3Server_3.0.7.zip \

### 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
|
|
|
|
### Using a client-made curseforge modpack
|
|
|
|
If you use something like curseforge, you may end up creating/using modpacks that do not
|
|
contain server mod jars. Instead, the curseforge setup has `manifest.json` files, which
|
|
will show up under `/data/FeedTheBeast/manifest.json`.
|
|
|
|
To use these packs you will need to:
|
|
|
|
- Specify the manifest location with env var `MANIFEST=/data/FeedTheBeast/manifest`
|
|
- Pick a relevant ServerStart.sh and potentially settings.cfg and put them in `/data/FeedTheBeast`
|
|
|
|
An example of the latter would be to use https://github.com/AllTheMods/Server-Scripts
|
|
There, you'll find that all you have to do is put `ServerStart.sh` and `settings.cfg` into
|
|
`/data/FeedTheBeast`, taking care to update `settings.cfg` to specify your desired version
|
|
of minecraft and forge. You can do this in the cli with something like:
|
|
|
|
```
|
|
$ wget https://raw.githubusercontent.com/AllTheMods/Server-Scripts/master/ServerStart.sh
|
|
$ wget https://raw.githubusercontent.com/AllTheMods/Server-Scripts/master/settings.cfg
|
|
$ vim settings.cfg #update the forge version to the one you want. Your manifest.json will have it
|
|
$ chmod +x ServerStart.sh
|
|
$ docker run -itd --name derpcraft \
|
|
-e MANIFEST=/data/FeedTheBeast/manifest.json \
|
|
-v $PWD/ServerStart.sh:/data/FeedTheBeast/ServerStart.sh \
|
|
-v $PWD/settings.cfg:/data/FeedTheBeast/settings.cfg \
|
|
-e VERSION=1.12.2\
|
|
-e TYPE=CURSEFORGE\
|
|
-e CF_SERVER_MOD=https://minecraft.curseforge.com/projects/your_amazing_modpack/files/2670435/download\
|
|
-p 25565:25565\
|
|
-e EULA=TRUE\
|
|
--restart=always\
|
|
itzg/minecraft-server
|
|
```
|
|
|
|
Note the `CF_SERVER_MOD` env var should match the url to download the modpack you are targeting.
|
|
|
|
## Running a SpongeVanilla server
|
|
|
|
Enable SpongeVanilla server mode by adding a `-e TYPE=SPONGEVANILLA` to your command-line.
|
|
By default the container will run the latest `STABLE` version.
|
|
If you want to run a specific version, you can add `-e SPONGEVERSION=1.11.2-6.1.0-BETA-19` to your command-line.
|
|
|
|
docker run -d -v /path/on/host:/data -e TYPE=SPONGEVANILLA \
|
|
-p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
|
|
|
|
You can also choose to use the `EXPERIMENTAL` branch.
|
|
Just change it with `SPONGEBRANCH`, such as:
|
|
|
|
$ docker run -d -v /path/on/host:/data ... \
|
|
-e TYPE=SPONGEVANILLA -e SPONGEBRANCH=EXPERIMENTAL ...
|
|
|
|
## Running a Fabric Server
|
|
|
|
Enable Fabric server mode by adding a `-e TYPE=FABRIC` to your command-line.
|
|
By default the container will run the latest version of [Fabric server](http://fabricmc.net/use/)
|
|
but you can also choose to run a specific version with `-e FABRICVERSION=0.5.0.32`.
|
|
|
|
$ docker run -d -v /path/on/host:/data -e VERSION=1.14.3 \
|
|
-e TYPE=FABRIC -e FABRICVERSION=0.5.0.32 \
|
|
-p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
|
|
|
|
To use a pre-downloaded Fabric installer, place it in the attached `/data` directory and
|
|
specify the name of the installer file with `FABRIC_INSTALLER`, such as:
|
|
|
|
$ docker run -d -v /path/on/host:/data ... \
|
|
-e FABRIC_INSTALLER=fabric-installer-0.5.0.32.jar ...
|
|
|
|
To download a Fabric installer from a custom location, such as your own file repository, specify
|
|
the URL with `FABRIC_INSTALLER_URL`, such as:
|
|
|
|
$ docker run -d -v /path/on/host:/data ... \
|
|
-e FORGE_INSTALLER_URL=http://HOST/fabric-installer-0.5.0.32.jar ...
|
|
|
|
In both of the cases above, there is no need for the `VERSION` or `FABRICVERSION` variables.
|
|
|
|
In order to add mods, you have two options.
|
|
|
|
### Using the /data volume
|
|
|
|
This is the easiest way if you are using a persistent `/data` 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:
|
|
|
|
```
|
|
/path/on/host
|
|
├── mods
|
|
│ └── ... INSTALL MODS HERE ...
|
|
├── config
|
|
│ └── ... CONFIGURE MODS HERE ...
|
|
├── ops.json
|
|
├── server.properties
|
|
├── whitelist.json
|
|
└── ...
|
|
```
|
|
|
|
If you add mods 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.
|
|
|
|
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.
|
|
|
|
## 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 PaperSpigot, it would look something like this:
|
|
|
|
```
|
|
docker run -d -v /path/on/host:/data \
|
|
-e TYPE=PAPER -e VERSION=1.14.1 -e FORCE_REDOWNLOAD=true \
|
|
-p 25565:25565 -e EULA=TRUE --name mc itzg/minecraft-server
|
|
```
|
|
|
|
## Using Docker Compose
|
|
|
|
Rather than type the server options below, the port mappings above, etc
|
|
every time you want to create new Minecraft server, you can now use
|
|
[Docker Compose](https://docs.docker.com/compose/). Start with a
|
|
`docker-compose.yml` file like the following:
|
|
|
|
```
|
|
minecraft-server:
|
|
ports:
|
|
- "25565:25565"
|
|
|
|
environment:
|
|
EULA: "TRUE"
|
|
|
|
image: itzg/minecraft-server
|
|
|
|
container_name: mc
|
|
|
|
tty: true
|
|
stdin_open: true
|
|
restart: always
|
|
```
|
|
|
|
and in the same directory as that file run
|
|
|
|
docker-compose up -d
|
|
|
|
Now, go play...or adjust the `environment` section to configure
|
|
this server instance.
|
|
|
|
## Server configuration
|
|
|
|
By default the server configuration will be created and set based on the following
|
|
environment variables, but only the first time the server is started. If the
|
|
`server.properties` file already exists, the values in them will not be changed.
|
|
|
|
If you would like to override the server configuration each time the container
|
|
starts up, you can set the OVERRIDE_SERVER_PROPERTIES environment variable like:
|
|
|
|
docker run -d -e OVERRIDE_SERVER_PROPERTIES=true ...
|
|
|
|
This will reset any manual configuration of the `server.properties` file, so if
|
|
you want to make any persistent configuration changes you will need to make sure
|
|
you have properly set the proper environment variables in your docker run command (described below).
|
|
|
|
### Server name
|
|
|
|
The server name (e.g. for bungeecord) can be set like:
|
|
|
|
docker run -d -e SERVER_NAME=MyServer ...
|
|
|
|
### Server port
|
|
|
|
The server port can be set like:
|
|
|
|
docker run -d -e SERVER_PORT=25565 ...
|
|
|
|
### 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.
|
|
|
|
### Whitelist Players
|
|
|
|
To whitelist players for your Minecraft server, pass the Minecraft usernames separated by commas via the `WHITELIST` environment variable, such as
|
|
|
|
docker run -d -e WHITELIST=user1,user2 ...
|
|
|
|
If the `WHITELIST` environment variable is not used, any user can join your Minecraft server if it's publicly accessible.
|
|
|
|
### Op/Administrator Players
|
|
|
|
To add more "op" (aka adminstrator) users to your Minecraft server, pass the Minecraft usernames separated by commas via the `OPS` environment variable, such as
|
|
|
|
docker run -d -e OPS=user1,user2 ...
|
|
|
|
### Server icon
|
|
|
|
A server icon can be configured using the `ICON` variable. The image will be automatically
|
|
downloaded, scaled, and converted from any other image format:
|
|
|
|
docker run -d -e ICON=http://..../some/image.png ...
|
|
|
|
### Rcon
|
|
|
|
To use rcon use the `ENABLE_RCON` and `RCON_PASSORD` variables.
|
|
By default rcon port will be `25575` but can easily be changed with the `RCON_PORT` variable.
|
|
|
|
docker run -d -e ENABLE_RCON=true -e RCON_PASSWORD=testing
|
|
|
|
### Query
|
|
|
|
Enabling this will enable the gamespy query protocol.
|
|
By default the query port will be `25565` (UDP) but can easily be changed with the `QUERY_PORT` variable.
|
|
|
|
docker run -d -e ENABLE_QUERY=true
|
|
|
|
|
|
### Max players
|
|
|
|
By default max players is 20, you can increase this with the `MAX_PLAYERS` variable.
|
|
|
|
docker run -d -e MAX_PLAYERS=50
|
|
|
|
|
|
### Max world size
|
|
|
|
This sets the maximum possible size in blocks, expressed as a radius, that the world border can obtain.
|
|
|
|
docker run -d -e MAX_WORLD_SIZE=10000
|
|
|
|
### Allow Nether
|
|
|
|
Allows players to travel to the Nether.
|
|
|
|
docker run -d -e ALLOW_NETHER=true
|
|
|
|
### Announce Player Achievements
|
|
|
|
Allows server to announce when a player gets an achievement.
|
|
|
|
docker run -d -e ANNOUNCE_PLAYER_ACHIEVEMENTS=true
|
|
|
|
### Enable Command Block
|
|
|
|
Enables command blocks
|
|
|
|
docker run -d -e ENABLE_COMMAND_BLOCK=true
|
|
|
|
### Force Gamemode
|
|
|
|
Force players to join in the default game mode.
|
|
|
|
* false - Players will join in the gamemode they left in.
|
|
* true - Players will always join in the default gamemode.
|
|
|
|
`docker run -d -e FORCE_GAMEMODE=false`
|
|
|
|
### Generate Structures
|
|
|
|
Defines whether structures (such as villages) will be generated.
|
|
|
|
* false - Structures will not be generated in new chunks.
|
|
* true - Structures will be generated in new chunks.
|
|
|
|
`docker run -d -e GENERATE_STRUCTURES=true`
|
|
|
|
### Hardcore
|
|
|
|
If set to true, players will be set to spectator mode if they die.
|
|
|
|
docker run -d -e HARDCORE=false
|
|
|
|
### Snooper
|
|
|
|
If set to false, the server will not send data to snoop.minecraft.net server.
|
|
|
|
docker run -d -e SNOOPER_ENABLED=false
|
|
|
|
### Max Build Height
|
|
|
|
The maximum height in which building is allowed.
|
|
Terrain may still naturally generate above a low height limit.
|
|
|
|
docker run -d -e MAX_BUILD_HEIGHT=256
|
|
|
|
### Max Tick Time
|
|
|
|
The maximum number of milliseconds a single tick may take before the server watchdog stops the server with the message, A single server tick took 60.00 seconds (should be max 0.05); Considering it to be crashed, server will forcibly shutdown. Once this criteria is met, it calls System.exit(1).
|
|
Setting this to -1 will disable watchdog entirely
|
|
|
|
docker run -d -e MAX_TICK_TIME=60000
|
|
|
|
### Spawn Animals
|
|
|
|
Determines if animals will be able to spawn.
|
|
|
|
docker run -d -e SPAWN_ANIMALS=true
|
|
|
|
### Spawn Monsters
|
|
|
|
Determines if monsters will be spawned.
|
|
|
|
docker run -d -e SPAWN_MONSTERS=true
|
|
|
|
### Spawn NPCs
|
|
|
|
Determines if villagers will be spawned.
|
|
|
|
docker run -d -e SPAWN_NPCS=true
|
|
|
|
### Set spawn protection
|
|
|
|
Sets the area that non-ops can not edit (0 to disable)
|
|
|
|
docker run -d -e SPAWN_PROTECTION=0
|
|
|
|
### View Distance
|
|
Sets the amount of world data the server sends the client, measured in chunks in each direction of the player (radius, not diameter).
|
|
It determines the server-side viewing distance.
|
|
|
|
docker run -d -e VIEW_DISTANCE=10
|
|
|
|
### Level Seed
|
|
|
|
If you want to create the Minecraft level with a specific seed, use `SEED`, such as
|
|
|
|
docker run -d -e 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.gamepedia.com/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 ...
|
|
|
|
### Message of the Day
|
|
|
|
The message of the day, shown below each server entry in the UI, can be changed with the `MOTD` environment variable, such as
|
|
|
|
docker run -d -e 'MOTD=My Server' ...
|
|
|
|
If you leave it off, a default is computed from the server type and version, such as
|
|
|
|
A Paper Minecraft Server powered by Docker
|
|
|
|
when `TYPE` is `PAPER`. That way you can easily differentiate between several servers you may have started.
|
|
|
|
_The example shows how to specify a server message of the day that contains spaces by putting quotes
|
|
around the whole thing._
|
|
|
|
### PVP Mode
|
|
|
|
By default, servers are created with player-vs-player (PVP) mode enabled. You can disable this with the `PVP`
|
|
environment variable set to `false`, such as
|
|
|
|
docker run -d -e PVP=false ...
|
|
|
|
### 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, such as
|
|
|
|
* DEFAULT
|
|
* FLAT
|
|
* LARGEBIOMES
|
|
* AMPLIFIED
|
|
* CUSTOMIZED
|
|
* BUFFET
|
|
|
|
Descriptions are available at the [gamepedia](http://minecraft.gamepedia.com/Server.properties).
|
|
|
|
When using a level type of `FLAT`, `CUSTOMIZED`, and `BUFFET`, you can further configure the world generator
|
|
by passing [custom generator settings](http://minecraft.gamepedia.com/Superflat).
|
|
**Since generator settings usually have ;'s in them, surround the -e value with a single quote, like below.**
|
|
|
|
For example (just the `-e` bits):
|
|
|
|
-e LEVEL_TYPE=flat -e 'GENERATOR_SETTINGS=3;minecraft:bedrock,3*minecraft:stone,52*minecraft:sandstone;2;'
|
|
|
|
### 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 'RESROUCE_PACK=http\://link.com/to/pack.zip?\=1' -e 'RESOURCE_PACK_SHA1=d5db29cd03a2ed055086cef9c31c252b4587d6d0'
|
|
|
|
**NOTE:** `:` and `=` must be escaped using `\`. The checksum plain-text hexadecimal.
|
|
|
|
### 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.
|
|
|
|
### Downloadable world
|
|
|
|
Instead of mounting the `/data` volume, you can instead specify the URL of
|
|
a ZIP file containing an archived world. This will be downloaded, and
|
|
unpacked in the `/data` directory; if it does not contain a subdirectory
|
|
called `world/` then it will be searched for a file `level.dat` and the
|
|
containing subdirectory renamed to `world`. This means that most of the
|
|
archived Minecraft worlds downloadable from the Internet will already be in
|
|
the correct format.
|
|
|
|
The ZIP file may also contain a `server.properties` file and `modules`
|
|
directory, if required.
|
|
|
|
docker run -d -e WORLD=http://www.example.com/worlds/MySave.zip ...
|
|
|
|
**NOTE:** Unless you also mount `/data` as an external volume, this world
|
|
will be deleted when the container is deleted.
|
|
|
|
**NOTE:** This URL must be accessible from inside the container. Therefore,
|
|
you should use an IP address or a globally resolveable FQDN, or else the
|
|
name of a linked container.
|
|
|
|
### Cloning world from a container path
|
|
|
|
The `WORLD` option can also be used to reference a directory that will be used
|
|
as a source to clone the world directory.
|
|
|
|
For example, the following would initially clone the world's content
|
|
from `/worlds/basic`. Also notice in the example that you can use a
|
|
read-only volume attachment to ensure the clone source remains pristine.
|
|
|
|
```
|
|
docker run ... -v $HOME/worlds:/worlds:ro -e WORLD=/worlds/basic
|
|
```
|
|
|
|
### Downloadable mod/plugin pack for Forge, Bukkit, and Spigot Servers
|
|
|
|
Like the `WORLD` option above, you can specify the URL of a "mod pack"
|
|
to download and install into `mods` for Forge 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 individual mods using the `MODS` environment variable and supplying the URL
|
|
to the jar files. Multiple mods/plugins should be comma separated.
|
|
|
|
docker run -d -e MODS=https://www.example.com/mods/mod1.jar,https://www.example.com/mods/mod2.jar ...
|
|
|
|
### 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 ...
|
|
|
|
**WARNING:** All content of the `mods` or `plugins` directory will be deleted
|
|
before unpacking new content from the MODPACK or MODS.
|
|
|
|
### Online mode
|
|
|

By default, server checks connecting players against Minecraft's account database. If you want to create an offline server or your server is not connected to the internet, you can disable the server to try connecting to minecraft.net to authenticate players with environment variable `ONLINE_MODE`, like this
|
|
|
|
docker run -d -e ONLINE_MODE=FALSE ...
|
|
|
|
### Allow flight
|
|
|
|
Allows users to use flight on your server while in Survival mode, if they have a mod that provides flight installed.
|
|
|
|
-e ALLOW_FLIGHT=TRUE|FALSE
|
|
|
|
## Miscellaneous Options
|
|
|
|
### Running as alternate user/group ID
|
|
|
|
By default, the container will switch to user ID 1000 and group ID 1000;
|
|
however, you can override those values by setting `UID` and/or `GID` as environmental entries, during the `docker run` command.
|
|
|
|
-e UID=1234
|
|
-e GID=1234
|
|
|
|
The container will also skip user switching if the `--user`/`-u` argument
|
|
is passed to `docker run`.
|
|
|
|
### Memory Limit
|
|
|
|
By default, the image declares a Java initial and maximum memory 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 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]`. For example:
|
|
|
|
-e MEMORY=2G
|
|
|
|
### JVM Options
|
|
|
|
General JVM options can be passed to the Minecraft Server invocation by passing a `JVM_OPTS`
|
|
environment variable. Options like `-X` that need to proceed general JVM options can be passed
|
|
via a `JVM_XX_OPTS` environment variable.
|
|
|
|
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`.
|
|
|
|
### HTTP Proxy
|
|
|
|
You may configure the use of an HTTP/HTTPS proxy by passing the proxy's URL via the `PROXY`
|
|
environment variable. In [the example compose file](docker-compose-proxied.yml) it references
|
|
a companion squid proxy by setting the equivalent of
|
|
|
|
-e PROXY=proxy:3128
|
|
|
|
### Using "noconsole" option
|
|
|
|
Some older versions of Spigot required `--noconsole` to be passed when detaching stdin. You can
|
|
pass that at the end of `docker run` after the image name or set `-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`.
