One evil at a time. Don’t let perfect be the enemy of good.

From my experience with sonarr and radarr, I thought lidarr would be great, but it’s garbage.

Bandcamp isn’t what it used to be, apparently there’s a better service for music now, I’m sorry I can’t recall the name.

Navidrome should serve you well for Spotify replacement. It uses the subsonic api, so you can use any app that supports that, and there are many.

Regarding sync phone with server, you might want some thing like synching or nextcloud with a local player on your phone. My music collection is 1.5TB, so I simply stream and have only a few select albums downloaded locally on the phone.

I just snapshot the parent lxc. The data itself isn’t part of the container at any level, so if I bung up compose yml or env, I can just flip it back. The only real benefit is that all my backups are in the same place in the same format.

Like I’m not actually opposed to managing docker in one unit, I just haven’t got there yet and this has worked so far.

If I were to move to a single platform for several docker, what would you suggest? For admin and backups?

I use individual lxc for each docker compose so I don’t have to revert 8 services at once if I need to restore.

I would also argue that an alpine lxc runs in 22mb ram by itself … Significantly smaller footprint on disk and in memory. But most importantly, lxc can actually share memory space effectively, one doesn’t need to reserve blocks of ram.
