Unable to create new containers with 1.20.5 and 1.20.6

[danabrey]

Describe the problem

I'm having an issue creating new containers for version 1.20.5 and 1.20.6 on Ubuntu 22.04.

I've pulled the latest versions of both of the java17 and java21 tagged images. I may be doing something silly!

Container definition

With java21:

version: "3"
services:
  server:
    image: itzg/minecraft-server:java21
    volumes:
      - /data/minecraft-challenge-2024:/data
    ports:
      - "25565:25565"
    environment:
      - "EULA=TRUE"
      - "VERSION=1.20.6"
      - "MEMORY=4G"

With java17:

version: "3"
services:
  server:
    image: itzg/minecraft-server:java17
    volumes:
      - /data/minecraft-challenge-2024:/data
    ports:
      - "25565:25565"
    environment:
      - "EULA=TRUE"
      - "VERSION=1.20.6"
      - "MEMORY=4G"

Container logs

With java21:

You definitely need to be using the java21 image but note the error

server_1  | [init] ERROR: your Docker provider has an annoying flaw where it
server_1  | [init]        tries to set PATH even though the container establishes
server_1  | [init]        a very specific value.

Are you using Portainer? It's usually the one that breaks the PATH variable like that.

A docker compose down and then docker compose up -d might fix it since it would give a fresh container (but existing volume mapping) to be created.

[danabrey]

Hmm, no, I'm just using regular docker and docker compose via the CLI.

I'll make sure I'm not using super old versions, it could be that.

[JohnyRicio]

I have same issue on my server and also on the local machine.

Error: LinkageError occurred while loading main class net.minecraft.bundler.Main java.lang.UnsupportedClassVersionError: net/minecraft/bundler/Main has been compiled by a more recent version of the Java Runtime (class file version 65.0), this version of the Java Runtime only recognizes class file versions up to 61.0

I am traiing to start server on my qnap ts431 server and there I need to run from image java17, because of arm32. On my local windows machine it does not work as well with same error. Looks like that old version of java is inside of the container.

When I modified the version and set 1.20.4 that it is looks like that it works.

[darkweasel77]

Same issue - regular docker and docker-compose

docker-compose up

[itzg]

@darkweasel77 , run the following and provide the output of those

docker image inspect -f '{{json .Config.Labels}}' itzg/minecraft-server
docker run --rm --entrypoint bash itzg/minecraft-server -c 'echo $PATH; ls -l /opt/java/openjdk/bin/java'

[darkweasel77]

If I specify something other than latest (say java11 or java17):

  mcworld:
    container_name: mcworld
    image: itzg/minecraft-server:java11
    ports:
      - 25565:25565
    environment:
      EULA: "TRUE"
    volumes:
      - ./_minecraft:/data
    restart: unless-stopped

I get:

@itzg I just installed jdk21 to see if that made a difference.

[itzg]

@darkweasel77 I really wanted to see what image you had pulled previously, which is why I requested the output of the specific command I provided. In any case, It'll probably work now.

[darkweasel77]

@itzg I'll set it back; w/ jdk21 I'm back to getting what I posted above.

If i use:

  mcworld:

    image: itzg/minecraft-server:latest
    ports:
      - 25565:25565
    environment:

[itzg]

Thanks @darkweasel77 , that context seems interesting but I have no idea what it means 😀 The Java 21 is also from Eclipse Temurin so there's not a distro difference from Java 17.

I'd say try googling for the Java VM error it's giving.

[darkweasel77]

@itzg FYI - I upgraded my version of docker on my server to the latest and the problem went away.

could you give us docker versions for comparison? @darkweasel77

[darkweasel77]

@VictorDrijkoningen I didn't copy the output of docker version prior to upgrade, but it was 1.xx something. Docker-compose was a unique install, not part of the system.

now:

Docker-compose was a unique install, not part of the system

Speaking of which, the separate docker-compose tool has been deprecated for a long time now. Instead use the builtin docker compose subcommand.

[darkweasel77]

I don't disagree - I had configured this server awhile ago with ubuntu 20.04, upgraded to 22.04 but never changed docker since it 'worked'.

I followed this guide from docker to upgrade my docker sub-system.

[itzg]

Sorry @darkweasel77 , that comment was really directed at anyone else reading this issue 😄
