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.

Glad to hear I'm not crazy with different distros haha. I wanted to be able to have different "enviroments" to keep familiar with release schedules, package managers, and just the flow of the distro. I've been using nothing but Debian/Ubuntu in my homelab for ~10 years now, at work we use RHEL, and for my desktops I'm on Arch. I'll have to look into pinning.

I've never heard of Nomad(love the name) so I'll definitely add it to my list of things to research. Looking at their site it looks solid, but want to weigh my options once I've loomed at everything.

And thanks for your comment! I've been doing this a long time and nothing "tickles" my brain more than something in my homelab breaking and I have to figure out how to fix it and then prevent it going forward.

Not crazy at all, actually, I can relate to some extent 😂 although, I am super happy with Talos on my nodes 😇 I feel like I am…staying familiar - love the optimism! - by building container images based on different distros simply because, depending on what you want to package, you’re…encouraged by the individual devs to use this or that package manager anyway 😂 but sounds like you do enjoy pain, so go for it 😂
