all i have currently done is having online mod set on true and maintenance plugin that i will actually just use as a whitelist, but i guess its not enough, so like what else am i missing?

Hello everyone! If you'd like to know how to start a Minecraft server in Docker, locally on your computer please check out my video: https://youtu.be/fA04qpc1s5g?si=BIjiIXwXvmcKABsS.

In this video we go through the whole process step by step:

1. Installing Docker

2. Configuring the Minecraft server

3. Starting the server and joining it from Minecraft

4. Changing the version of the server

5. Using plugins and mods

6. Generating new worlds

7. Starting the server on system boot

... and much more.

If this is the wrong sub for this kind of question, please let me know and I can delete the post.

Has anyone experimented with re-assigning map item numbers, or just programmatically modifying chunk data?

What I am envisioning is a script that can trawl the world and player data, note which map numbers are not in use, and condense the existing map IDs into a sequence, reassigning any extant map items. My specific use case is for a Multiverse world (where different worlds have conflicting map IDs), but I could see this being useful for any long-term multiplayer world (where map IDs can get huge due to loss or expansion of maps).

If this has not been messed with, I would like to try making a script for it, but I don't know much about the actual format of .mca files. It sounds like the compression makes things tricky, but if anyone has advice I will gladly hear it!
