| Some software really prefers to control the whole host, usually highly integrated stuff. Some examples: - Unifi Controller installs like a half dozen dependencies to run (Mongo, Redis, etc last time I used it), much easier to isolate all that in a VM - Home Assistant's preferable and most blessed install method is Home Assistant OS, which is an entire distribution. I've run HA in Docker myself before but the experience is like 10x better if you just let it control the OS itself - I have Plex,Sonarr,Radarr, etc running for media - there is software called Saltbox which integrates all of these things for you so that you don't need to configure 10 different things. Makes it a breeze, but requires a specific version of Ubuntu or you're in unsupported territory (kinda defeating the purpose) Lots of stuff you can be totally fine just using Docker or installing directly onto the host. But having the bare metal system running Proxmox from that start gives you a ton of flexibility to handle other scenarios. Worst case you just setup a single VM & run your stuff on it if you have no need for other types of installs. Nothing lost, but you gain flexibility in the future as well as easy backups via snapshotting, etc |
For major upgrades, I may go a step further and do a manual snapshot before upgrading and then decide whether or not to commit (usually) or rollback (easy, when needed).
The (emotional) security provided by this is nice, as is the time-savings (after initial time expense to learn and setup the base proxmox infrastructure).
