[Support] fithwum - minecraft server

[fithwum]

also for the fabric template if you already have it installed you will need to add more variables as you can also now pick whatever version of minecraft is supported by fabric YOU WILL NEED TO CHANGE THE DOCKER TAG TO fithwum/minecraft-fabric:latest

 

key: MC_VERSION

key: INSTALLER_VERSION

[fithwum]

for all running the vanilla minecraft you will also need to change your tag to latest and add the MC_VERSION variable this way you can select the version you want instead of waiting for me to add versions

Hi, I can't connect to the server from the local network (thus not from outside), when I look in the log, I see that the server is running and ready. In minecraft game it says Can't connect to server. I have the port and IP correct.

Looks like the container didn't map the ports. There is no network assigned. I don't know how to fix it.

 

EDIT: 

I just added a port to container and it works.

sorry forgot to update post i have updated the templates for vanilla and fabric you will need to add some variables this is for added functionality if you add the size variables you will need to delete your run file.

 

i removed the port mapping from the dockerfile so that it was possible to set the port and have it change the port in the settings file this works fine in my testing on 4 different servers so far. i made the changes as they were requested by many people.

 

NEEDED

key: GAME_PORT

 

OPTIONAL

key: XMX_SIZE

key: XMS_SIZE

key: XMN_SIZE

[strangeslinky2]

any changes I make to the ops.json are reverted once I restart the container, my understanding is that the restart pulls the default files. can I change this, or do I need to create a separate container?

 

Brand New to Unraid so I am open to recommendations.

[fithwum]

the only time it should be downloading a new file is when the file is not there at all.

all my minecraft dockers are not even setup to download any ops file at all anyway i removed that as it was only there for testing to make things faster for me.

 

the only other thing i can think of is that you dont have your data folders setup somehow.

I updated to MC Version 1.20.5 and now I am getting java related errors, I think the java version needs to be updated.

 

maybe update java to 22? I am not sure the best way to fix this.

[fithwum]

it seems that for right now this is not possible as starting with version 1.20.5 of minecraft it now requires java 21 and at this time it is not available on linux except for unstable testing.

 

i will be keeping an eye on this and try to work on a fix
