Unofficial MCSManager Docker Image with built-in OpenJDK

See official repo here

About v10

MCSManager is under a major update to v10, make sure to backup your data before upgrading.

Also, this repo is doing refactoring to support v10 (and provide better experience), please checkout v9 branch for old version.

OpenJDK Version

See official doc here to choose the right JDK version depending on your Minecraft server version.

There are two ways to specify JDK version:

  1. Use ngc7331/mcsmanager-daemon:latest-jdk${JDK_VERSION} tag to use the pre-installed Openjdk, e.g. ngc7331/mcsmanager-daemon:latest-jdk21 will give you an out-of-box OpenJDK 21.
    1. Use :latest-nojdk tag to skip the pre-installed JDK, and you can install it at runtime.
  2. Use -e JDK_VERSION=${COMMA_SEPARATED_JDK_VERSION} to specify the JDK version, e.g. -e JDK_VERSION=11,17 will install OpenJDK 11 and 17 at runtime, note that this will take some time, and will run every time you re-create the container. The pre-installed JDK will be ignored.

For example, if you run docker run ... -e JDK_VERSION=17,21 ... ngc7331/mcsmanager-daemon:latest-jdk17, you will get something like this in the log:

[init-jdk] Setting up JDK...

...

You can use /usr/lib/jvm/java-${JDK_VERSION}-openjdk/bin/java (or java${JDK_VERSION} for short) to run your Minecraft server with the specified JDK version. /usr/lib/jvm/default-jvm/bin/java (or java for short) points to the pre-installed JDK version.

Currently, the latest tag is equivalent to latest-jdk21.

Usage

Run Daemon

$ docker run -d --name mcsm-daemon \
             -p 24444:24444 \
             -p 25565-25575:25565-25575 \
             -v your/path/to/data:/opt/mcsm/daemon/data \
             -v your/path/to/logs:/opt/mcsm/daemon/logs \
             -v /var/run/docker.sock:/var/run/docker.sock \
             ngc7331/mcsmanager-daemon:<tag>

Notes:

  1. Replace your/path/to/xxx with your actual path
  2. Replace <tag> with latest or any valid tag, checkout tags on Docker Hub
  3. If you don't want use mcsm to control docker, remove -v /var/run/docker.sock:/var/run/docker.sock \
