docker-minecraft

A nice and easy way to get a Minecraft server up and running using docker. For help on getting started with docker see the official getting started guide. For more information on Minecraft and check out it's website.

Building docker-minecraft

Running this will build you a docker image with the latest version of both docker-minecraft and Minecraft itself.

git clone https://github.com/overshard/docker-minecraft
cd docker-minecraft
sudo docker build -t overshard/minecraft .

Running docker-minecraft

Running the first time will set your port to a static port of your choice so that you can easily map a proxy to. If this is the only thing running on your system you can map the port to 25565 and no proxy is needed. i.e. -p=25565:25565 . If you want to enable the query protocol you need to add another -p=25565:25565/udp to forward the UDP protocol on the same port as well. Also be sure your mounted directory on your host machine is already created before running mkdir -p /mnt/minecraft.

sudo docker run -d=true -p=25565:25565 -v=/mnt/minecraft:/data overshard/minecraft /start

From now on when you start/stop docker-minecraft you should use the container id with the following commands. To get your container id, after you initial run type sudo docker ps and it will show up on the left side followed by the image name which is overshard/minecraft:latest.

sudo docker start <container_id>
sudo docker stop <container_id>

Notes on the run command

• -v is the volume you are mounting -v=host_dir:docker_dir
• overshard/minecraft is simply what I called my docker build of this image
• -d=true allows this to run cleanly as a daemon, remove for debugging
• -p is the port it connects to, -p=host_port:docker_port
