Proxmox HA, Docker Swarm, Kubrenetes, or what? (lemmy.world)

I've gotten to the point where I have more than a few servers in my homelab and am looking for a way to increase reliability in case of an update. Two problems: 2 of the servers will be on Wifi and one is a Synology NAS. I can't do any wiring but I can put together a WiFi 6E network for the servers only, That means buying 4 Wifi 6E devices in a mix of types. As for Synology, it's container manager is a little odd so I expect to run a Linux VM and use that as my cluster node. That may mean buying more RAM as I haven't upgraded it. Hardware ranges from a 6 core CPU on the NAS (with a few important docker containers), 8 core on my main SFF server (which also runs my OpnSense VM inside Proxmox), 16 core Ryzen on my old big server, and a 10 year old NUC for fun. So the question is what do I use to orchestrate all the services I have. My Vaulwarden runs reliability but only on one system. I want better reliability for Pihole that automatically syncs settings. The NAS' docker implementation doesn't support gravity sync. Since everything I do runs in docker besides storage it seems Proxmox clusters is not the best option. That puts me between K8s and Docker Swarm. I'd like something that is simple to administer but resilien when hardware fails.

First off, replace WiFi with Ethernet. Seriously, it will be way more reliable. There are plenty of janky adapters that will work fine.

Once you have that done you can setup a Proxmox cluster. Proxmox won't be a good experience with WiFi.

OP can try power line if nothing else works

Late reply but yeah, Wifi was a nightmare on Proxmox. It was a tiny e-waste SFF pc so I was able to wedge it near the other servers. The cluster is happy.

Not sure if this is what you mean, but I have my proxmox server connected via a WiFi bridge and there have been zero issues in the past year that I’m using it. Set it up to try and see if it works and haven’t had to change it so I didn’t. Mainly home assistant on the server, no media streaming or other realtime stuff, so that may be why.
