Proxmox Homelab - Docker Swarm Still Viable? Using Different Distros as VMs? (lemmy.world)

My homelab is essentially my own passion project and only really I access it except for when I spin up the occasional game server for friends.

I'm currently running Proxmox and run a debian LXC container for each docker stack I have, and have OpnSense routing incoming traffic with Haproxy with ssl offloading. My currently running LXCs are: mediawiki, amp game server(2 Minecraft servers), freshrss, and currently playing around with n8n.

I'm looking to collapse my LXC's to just VMs. I'd like to be able to have 3 VMs running in a Docker Swarm together so I can upgrade a VM at a time and just swing my running containers to another docker node and then swing back when the VM is stable again.

I've looked at k0s, k3s, and k8s and it just seems way too much work and overhead for what I'm willing to do. I also want to keep using docker compose and want a decent webgui to manage my containers/nodes/swarm. I'm using DockHand right now, but need to research swarm support.

Anyone have any advice for something like this? Any specific terms, tech, software I should look into?

Also, gonna throw a curveball, but what would the effects be of running 3 different distros as my nodes in my swarm? Like a Debian node, Rocky Linux node and potentially arch node? I'm guessing I shouldn't due to docker engine differences potentially.

I'm just trying to have fun with things, break things, fix them, learn, etc.

I'm running dokploy in swarm mode on 3 nodes.

The only downside is the development of swarm is basically halted and some features are missing (like passing /dev devices to a container, you have to use dirty workarounds) but otherwise it just works.
