I cannot speak to collaborative editing of documents, but I do run my own docker-based nextcloud server for my own data.

I use nextcloud for:

• files
• photos (via memories app)
• contacts
• calendar
• tasks
• notes

I am not using the AIO docker image, I am using the nextcloud:APP_VERSION image, with APP_VERSION being 33 currently, preparing to upgrade to 34. My SSL-certificate is done via nginx-proxy-manager, as it was easy to setup on a different VM and it acts as a gateway to my internal services.

Syncing files, contacts and calendar works very well with my Graphene OS Pixel 9a (via the F-Droid App DAVx5, as well as my EndeavourOS desktop. The only thing I can really complain about is the documentation for selfhosting, as it seems to be missing some info. Or maybe I just didn’t find it.

If you’re interested, I can share my setup consisting of

• docker-compose.yml for local tests
• docker-compose.production.yml for production and staging deploy
• Dockerfile for nextcloud + cron container (though I may replace this with ofelia)
• Starter-Script for local tests
• GitLab CI pipeline for production and staging deploy

It may be a bit over-engineered though.
