docker-minecraft

A docker wrapper for running a minecraft server with automated backups. It includes a feature in which you can write commands to a file and they will be run in the server console.

How to use it:

1. clone this repo
2. run the docker container as follows (or use the included docker-compose.yml file):

docker run -d -p 25565:25565 -v <your minecraft data dir>:/etc/minecraft/data -v <your minecraft backups dir>:/etc/minecraft/backups minecraft:<server version>

3. Minecraft generates a file called eula.txt in the data directory. You must edit this file from "false" to "true" to indicate that you accept the eula. Then stop and restart the docker image.

Note: if you run this with docker-compose (see the included docker-compose.yml file), the "restart: always" command causes the server to automatically restart when/if it crashes or if you stop it by writing "stop" in the cmdfile.

Configure backups

By default the backups run at 05:30. To change this, include the environment variable CUSTOM_BACKUP_TIME and set it to a four-character string of the desired hours and minutes, eg. 0530.

Commands in the console

To run a command in the minecraft server console, just navigate to your minecraft data directory and replace the file cmdfile with one containing your command, like this:

echo "time set day" > cmdfile

The file will be truncated and the command will be run.
