Correct me if I’m wrong: of the community projects that you list, I don’t think any is meant to be added inside of the server image…
The Android TV app is for installation on the Android TV platform.
The Kodi plugin appears to be an Immich plugin for Kodi, rather than a Kodi plugin for Immich.
The other three (as well as the official CLI) appear to be standalone tools that only access Immich through its web API?
Only “Create albums from folders” even suggests that you install it by adding it to your Docker Compose file (which is outside of the server image). But that seems to be just for convenience among people who maintain a Docker Compose file to launch Immich as per recommendation. There’s no reason not to launch this other tool/client standalone.
