simple docker container for a minecraft server
This is based heavily on https://github.com/itzg/dockerfiles (I didn't want to fork the entire repo which contains many different dockerfiles)
The data-only container is simple, but was intially based on:
https://registry.hub.docker.com/u/aduermael/minecraft-data/
Starting from scratch:
clone this repo
Prep the server image (this part is kinda clunky and should be generalized one day. see the issues)
$ cd mcserver
edit the following variables in start-minecraft.sh (one day this should be an external file)
gamename='monster' #shortname
url="http://www.creeperrepo.net/FTB2/modpacks%5EMonster%5E1_1_1%5EMonsterServer.zip" #point to whichever server.zip you want to play
rawzip="modpacks^Monster^1_1_1^MonsterServer.zip" #could use regex and ${url} to automatically set
jarfile="FTBServer-1.6.4-965.jar" #the jar file to run from within the zip.
Build the images:
$ cd mcserver
$ docker build -t jmbjr/mcserver-monster .
$ cd ../mcdata
$ docker build -t jmbjr/mcdata
view your images with:
$ docker images
Run the containers:
need to run the data container first:
$ docker run -d -it --name mcdata-mon jmbjr/mcdata
-d run daemonized
-it allow $ docker attach mcdata-mon
--name name the container for easy access later
run the server container and point to the data container:
$ docker run -e EULA=TRUE -d -it -p 25565:25565 --name mcserver-mon --volumes-from mcdata-mon jmbjr/mcserver-monster
-e set environemnt variable to accept the mojang EULA (see mcserver/README.md for more info)
-d run daemonized
-it allow $ docker attach mcserver-mon
-p connect to port external:internal (or whatever port you want to run the server on. internal port set in Dockerfile)
--name name the container for easy access later
--volumes-from point to our data-only mcdata container
view running containers via:
$ docker ps
view ALL containers, regardless of running or not via:
$ docker ps -a
view log file from a container (useful when docker ps doesn't show your container running)
$ docker logs <container --name>
attach to the container (to view the minecraft server console or to view the mc data)
$ docker attach <container --name>
use ctrl+p ctrl+q to detach
to start and stop the container:
$ docker start <container --name>
$ docker stop <container --name>
to remove/delete containers:
$ docker rm <container --name>
to remove/delete images
$ docker rmi <image --name>
