Ultimate Progression: Sky Shulker Tooltip has class loading errors

[Craneneaulos]

Describe the problem

Hello, I'm trying to set up a server on the Ultimate Progression modpack: Sky. Unfortunately, when launching my docker-compose file, I encounter an error that seems to be related to ShulkerTooltip. I'm unable to fix the error or generate an exclusion of the mod in my docker-compose file.

I'm posting the docker-compose and the end of the bug report below.

I was able to get it running by excluding the ShulkerTooltip mod which looks like you tried to do. This is the format I used:

CF_IGNORE_MISSING_FILES: |
  mods/ShulkerTooltip-1.10.jar

[rhullah]

I just realized I used the wrong option (even though it resulted in still excluding the mod). But it's likely better to use the proper option such as the following:

CF_EXCLUDE_MODS: shulker-tooltip

And that option supports:

passing a comma or space delimited list of project slugs or IDs

[Craneneaulos]

Okay, it works very well with the right option. When I tried to apply it, I must have done something wrong. After that, I still can't connect to the server. I already have a Minecraft server running on the machine. I would like both to work simultaneously, so I changed the ports on the new one as can be seen above in the docker-compose.yml.

But when I enter my IP with port 25566 on the modpack, I get the message: io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information."

[rhullah]

When you use a different port, you only should/need to change the host side (left of the colon), and leave the container side (right of the colon) as-is. So you would set it to: "25566:25565".

[Craneneaulos]

It's perfect! Everything works as it should. I'm new to docker and don't really understand how ports work yet.

[itzg]

Here's a diagram I had created to help visualize the port mappings

https://github.com/itzg/docker-minecraft-server/blob/master/notes/container-network-namespaces.drawio.png

[Craneneaulos]

Thank you for the diagrams, they are really clear and have helped me understand how it works.

However, when I came back from work, my first server was off and I couldn't restart it. So, I shut down everything, restarted my machine, and now neither of the two servers wants to boot up... I have the same error report for both servers. The only thing I changed was the API key because I thought that might be the issue, but it didn't solve the problem.

[rhullah]

Try it again. Others were having the same issue (#2748) and seems to be resolved now.

[Craneneaulos]

Indeed, the problem resolved itself after a few hours.
