USB hard drive? If we’re talking about a cold backup that’s easy to access a USB drive is reliable and easy.

Yeah pinning is great, you’ll still need watchtower for auto updates too

Komodo is a full management setup, similar to Portainer, Dockge, etc… It works reasonably well.

Watchtower doesn’t require any labeling unless you want to exclude a container.

but my main concern is having a breaking change be automatically updated

Pinning to a major version usually solves this, ie; instead of using postgres:latest use postgres:14 which will give you updates only from version 14.

But also have backups in place, worst case you just roll back to before it updated.

Maybe Karadav with the Nextcloud clients/apps.

Not sure if that will support selective sync, I don’t see anything saying specifically no on the repo.

Yeah give it a try, I use -75dBm as my setting. Currently only on the 5ghz band, but you can try on all of them, 2.4ghz might want more like -80dBm.

I run proxmox on the host with docker in a VM for 90% of my stuff, OS updates I do like every 6 months maybe, I’ve done 1 major version upgrade on proxmox with no issues at all.

The docker containers auto-update via Komodo, and nothing really ever breaks anymore other than the occasional container error that needs a simple fix.

Everything important is backed up nightly using both proxmox backup server, and to backblaze B2 with restic.

I’ve found that a lot of clients just don’t roam well, they hang on to even unusable weak signals.

On my Unifi setup I’ve ended up turning on minimum RSSI on the APs so they force kick off any devices with a signal that is too low. You end up with a delay of like 5-10 seconds while the client reconnects, but it does work.

You don’t need any guides for it except for really niche cases.

For example Ubuntu VM; click create VM, choose Linux for the type, click next a bunch and choose your ISO image, CPU cores, and RAM. And you’re done, there’s no specific settings to use.
