部署此镜像到 DaoCloud 平台时需要选择 tcp 协议 并挂载 volume 到 /data 否则重启镜像会造成存档消失!!

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 -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

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.

Mojang now requires accepting the 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

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.

NOTE: By default, the files in the attached directory will be owned by the host user with UID of 1000. You can use an different UID by passing the option:

-e UID=1000

replacing 1000 with a UID that is present on the host. Here is one way to find the UID given a username:

grep some_host_user /etc/passwd|cut -d: -f3

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 ...

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 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

In order to add mods, you have two options.

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

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.

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. 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 -d up

Now, go play...or adjust the environment section to configure this server instance.

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.

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.

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 ...

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 ...

If you want to create the Minecraft level with a specific seed, use SEED, such as

docker run -d -e SEED=1785852800490497919 ...

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 or the shortcut values:

• creative
• survival
• adventure
• spectator (only for Minecraft 1.8 or later)

For example:

docker run -d -e MODE=creative ...

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, the last used or default message will be used. The example shows how to specify a server message of the day that contains spaces by putting quotes around the whole thing.

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 ...

By default, a standard world is generated with hills, valleys, water, etc. A different level type can be configured by setting LEVEL_TYPE to

• DEFAULT
• FLAT
• LARGEBIOMES
• AMPLIFIED
• CUSTOMIZED

Descriptions are available at the gamepedia.

When using a level type of FLAT and CUSTOMIZED, you can further configure the world generator by passing custom generator settings. 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;'

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.

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.

The Java memory limit can be adjusted using the JVM_OPTS environment variable, where the default is the setting shown in the example (max and min at 1024 MB):

docker run -e 'JVM_OPTS=-Xmx1024M -Xms1024M' ...
