This container is based on ubi9-minimal, and uses graalvm-ce 17 JDK. The container is built specifically for use as a minecraft proxy. This issues has been fixed in it. This allows you to fully use it as a server container without errors related to some plugins.
All builds take place automatically without human intervention. If the main repository is updated, the build process starts and you get the latest version.
In entrypoint.sh
the start flags from Aikar's are specified. You can get them by following the link or on this website. entrypoint.sh
it has one variable - MEMORYSIZE
, which indicates how much will be allocated memory to the server (in this case, velocity) in -Xms and -Xmx. It is located here.
It is important! If you limit the container's memory using --memory
in the docker command, or memory
in docker-compose
, keep in mind that you need to allocate memory with a margin. If you specified 1G in MEMORYSIZE, then you need to specify at least 2G for the docker container.If you specify less, the JVM uses all the RAM, and your process will be stopped by OOMKiller. Multiply your allocated memory number by 2-3. This will help to avoid problems with stopping the container.
If you need to change the JDK or flags, you need to create the container yourself. You can find out how to do this in the how to build section.
