Support for copying different folders than /data/mods and /data/config etc.

Hey! Got a question. Is there a way to specify "extra" directories that would be managed in a similar way as the config directory?
I'll state my current use case for this: KubeJS scripts. There's a directory /data/kubejs, that contains the KubeJS scripts. I'd like the source for this folder to be in a git repo - same as my configs. Maybe possible to do using "Applying extra configuration files"? But for many files, I'd have to specify an exhaustive list...
I tried mounting a directory to /data/kubejs but that didn't seem to work.
Do you have some way to solve this? Thanks!

I can't remember if it'll do subdirectories, but you might be able to hack it in by setting COPY_CONFIG_DEST to /data and mounting the top level content at /config

As you mentioned APPLY_EXTRA_FILES is conceptually closest to what it sounds like you need. I'd also have to research if it accepts directories as the source for each entry.

I did confirm that each source entry of APPLY_EXTRA_FILES can be a directory. It doesn't yet recursively copy the content of the directories within those. So, perhaps listing the directories and subdirectories would suffice?

[SaimonWoidig]

Yeah, sure. I'll let you know how it went. And maybe this can be a feature request since I think I am not the only one using KubeJS.

On a side note - I must admit that the config copying utility is impressive. I especially like the fact that it can detect changes automatically.

Thanks!

This worked fine. Thanks again!

services:
  minecraft-server:
    environment:
      APPLY_EXTRA_FILES: |
        kubejs/server_scripts/</kubejs/server_scripts/hello.js
        kubejs/startup_scripts/</kubejs/startup_scripts/hello.js
    volume:
      - type: "bind"
        source: "./kubejs" # local dir with KubeJS scripts `server_scripts/hello.js` and `startup_scripts/hello.js`
        target: "/kubejs"
        read_only: true

EDIT: Hmm, it seems that the old scripts are not deleted, which makes sense since you also have to delete them from APPLY_EXTRA_FILES, othewise the script will error in a similar way to ERROR : Invalid parameter provided for 'mcopy' command: Source file '/kubejs/startup_scripts/nonexistent.js' does not exist.
If the copy script could be enhanced in such a way, that it supports whole dirs, it could then possibly watch all files in that dir, right? But this will do for now, thanks.

Yes, I mentioned the source can be directories and not just files. So try

      APPLY_EXTRA_FILES: |
        kubejs/server_scripts/</kubejs/server_scripts
        kubejs/startup_scripts/</kubejs/startup_scripts

[SaimonWoidig]

Ah that did the trick! Thanks!
The old scripts are still there but atleast I don't have to mention each script separately.
Maybe you can mention it in the docs/wiki, I'm sure it'll help someone.
