mcsrvod - Minecraft Server on Demand

What is this?

This is your ultimate docker container for running minecraft 1.7.10+ in any forms available, not wasting your resources.

tl;dr

1. Check your desired server software is compatible with 1.7.10+
2. Install docker on your host: (Ref)
3. Dont forget to accept the eula and configure everything, including the memory limit!
4. The port of your server software must listen on port 25565, this is the default.
5. Copy paste the sample docker-compose file

How does it work?

Mount your server folder unter /srv/mcsrvod/ and rename your jar file to server.jar.

The container will start the attached jar file when an connection to port 3000 is etablished. This is the public port for minecraft, you can change the outside mapping to whatever you like.

Known limitations

• This docker image is only suitable for minecraft 1.7.10+
• The log is not directly visible in docker logs, it must be read from the according file, due to independence of the server software

Configuration

Timeout to shutdown server after idle

You can specify the interval in seconds the server should shutdown than no one is online. To do so specify the environment variable KILL_INTERVAL

Customize start arguments

You can customize the jvm start arguments via an envrionment variable called JAVA_OPTS. Same goes for your server arguments, to specify them simply set the env for SERVER_OPTS

Troubleshooting

Server is not running after first launch

Please check if the eula.txt is created and its agreement is set, this must be done by yourself.

Server is not responding on connection immediately

The server may need some time to completely start, till that you will see an long running poll. For normal installations this is normally not that long, depending on your machine power. For modpacks this may take some time.
