Dockerfile for FTBLite2
This docker image provides a Minecraft Server, based on Feed The Beast Lite 2, that will automatically download the latest stable or any specific version.
To simply use the latest stable version, run:
docker run -d -p 25565:25565 rafaelmartins/ftblite2
where the default 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 service port 25566.
Speaking of multiple servers, it's handy to give your containers explicit names using
--name, such as
docker run -d -p 25565:25565 --name minecraft rafaelmartins/ftblite2
With that you can easily view the logs, stop, or re-start the container:
docker logs -f minecraft ( Ctrl-C to exit logs action ) docker stop minecraft docker start minecraft
Attaching data directory to host filesystem
In order to persist the Minecraft data, which you probably want to do for a real server setup, use the
-v argument to map a directory of the host to
docker run -d -v /path/on/host:/data -p 25565:25565 rafaelmartins/ftblite2
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.
To use a different Minecraft version, pass the
VERSION environment variable, which can have the value
- (or a specific version, such as "1.1.19")
For example, to use the latest version:
docker run -d -e VERSION=LATEST ...
or a specific version:
docker run -d -e VERSION=1.1.19 ...
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.
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 ...
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 2048 MB):
docker run -e 'JVM_OPTS=-Xmx2048M -Xms2048M' ...
