IMPORTANT - Log4j Vulnerability   There has been a report of a user running an unpatched version of Minecraft Java which was also exposed to the internet, this resulted in the log4j vulnerability being exploited and the user suffering from a hack against files exposed for the container (located in /config).    All users PLEASE keep in mind, if you wish to expose Minecraft servers to the internet then you must either:-   1.

hi, I am installing this for my kids but I don't know much about how the Minecraft server should work.

 

I can connect to it from the game. That is a good start.

 

To configure the server, I tried the web UI but when I type help, there is more than one screen and no way to scroll back... (?)

 

I tried to follow this manual page: https://github.com/binhex/documentation/blob/master/docker/faq/minecraftserver.md ... but the console thing does not seem to work.

 

Is there a way to use a console that is not through webui?

Thank you.

SSH into your server, and then I think you can docker exec into that container.  I apologize that i don't know the command off the top of my head.

 

Yes I understand I can docker exec into the container but then all I have is a linux shell prompt. What I'd like is to have a prompt from the server. Something where I can type "/help" or "/time set day"...

Having just installed the MC docker for the first time, I was impressed with how simple it was, and haven't had any problems so far.

 

I just wanted to ask - if CREATE_BACKUP_HOURS is non zero, a backup is created - but where is that backup created ? I've got some backups going to non-array devices and wondered if it was configurable somewhere ?

Hello, starting today I get this message.

 

Starting server
Unsupported Java detected (66.0). Only up to Java 21 is supported.

 

Just after updating to Unraid 6.12.9

 

I have another docker running minecraft and that one is fine, just one of them

 

Any guidance available?

Hi,

I just downloaded your minecraft docker image and tried changing the JAVA_VERSION to 8 and 11 and then the server won't start. Have any clues?

I'm trying to deploy a server and would like to use on Tlauncher : Fabric 1.20.1 , and I can't because it forces me to use the 1.20.5.

Appreciate the help, have a nice one !

Hi

I've just recently started using Unraid and set up a MC server for my kids.   I've changed the vanilla server to paper, and I'm looking to change the backups.   The current backups only copy the World folder, but paper MC splits this into 3 folders (world, wold_nether, and world_the_end).  Is it possible to edit the backup script to also copy these folders?

 

Thanks in advance!

I recently updated the Minecraft container on unRaid 6.12.8. I see this when I restart the container:

[11:56:09] [Server thread/INFO]: Starting minecraft server version 1.20.5

 

I use this tag in the repository field: binhex/arch-minecraftserver

 

Overnight, I see this in the WebUI. I wasn't getting this before on whatever the prior version was.

 

What's up with this error?

is this you?, if not then you are not alone:- 

 

not sure what this means, maybe minecraft dev's have made changes to the server in some way which is causing the error:-

The updates they did with data packs for 1.20.5 were extensive so this could be a possible answer

Nope, that isn't me.

 

Seems like the server works. I can join it from my client.

Guess I'll just wait to see what happens. Thanks for that Reddit thread.

I see the container updated to 1.20.6 today. Continuing to monitor.

Hi everyone,

I have been running this minecraft server for a few weeks now for just 3 people, nothing too intensive, but I am getting random JVM crashes that result in disconnects and progress loss. This is the error message that appears in the logs. I am running Minecraft 1.20.6

I tried manually setting the java version in the docker setup to java 17 but the server is not spinning up unless "latest" is specified for the java version.

If anybody is able to help me out that would be a great help.

Thank you

I tried manually setting the java version in the docker setup to java 17 but the server is not spinning up unless "latest" is specified for the java version.

If anybody is able to help me out that would be a great help.

Thank you

Do you see anything like this in the console?

Yes I do, they are sprinkled throughout the logs. They don't seem to correspond to crashes from what I can tell. This is one example of what it looks like for me if it helps.

Thanks. I get those "Netty Epoll Server IO" errors too but I don't think my server crashes. I can't find any threads where the Netty errors are being addressed. I'm stuck on 1.20.6 waiting for an update.

Hello everyone,
I have set up my server.

1. Now I would like to pre-generate a certain chunk size before someone joins the server. -> 4000x4000

2. Is there a way to have a dynamic map via docker container?

 

How can I accomplish this?

 

I have not found a command and most other solutions are not suitable for the latest vanilla Minecraft version.

 

Best regards

Ace

Hi Binhex or anyone else,

 

What am I supposed to do when for the docker or Minecraft server to restart after a crash or /stop command has been issued?

I tried adding --restart=unless-stopped parameters, but that didn't work.

 

Whenever the server crashes, it doesnt restart the docker nor the minecraft server thus needing a physical restart in Unraid itself.

Stopping the server via /stop also does the same. 

 

I'd like the server to be restarted after a /stop or crash.

 

How?


Thank you.

Apoloxy.
