I moved from Nextcloudpi some time back & found THIS TUTORIAL far & away the most useful. Instead of just saying copy/paste a Docker Compose file he shows how to build it step by step using Portainer so i found it invaluable for future projects.

It seems a bit overwhelming initially but once you’ve installed it a few times you’ll be able to do it from scratch in less than an hour. Probably less as it sounds like you already know what’s what having used Ansible

For me it’s the first thing i learned how to self host: Nextcloud …which in turn allows me to sync Joplin notes, which I use constantly

Great machines, I use an NUC8i7 as our HTPC. Supports 4K 60fps. Got it hooked up to a Denon amp for Dolby Atmos. At some point i hope I’ll find time to look into Home Assistant, I’d use another NUC for running that.
