I’ve yet to dig into the how , but I’m pretty sure you can set up a git workflow to build what #bluefin builds and then use your own customized docker file to add/remove apps and change settings to your liking.

I’m hoping to get this working myself when there are some ARM64 bluefin builds.

Thanks, that’s awesome news to see! I’m currently in the process of tearing out pieces from a monolithic docker stack into more lightweight (and independent) CTs, and have been apprehensive about moving NextCloud.
