Docker or Proxmox? Something else entirely? (piefed.social)

New server has been acquired. Debian 13 has been installed.

GS308EP switches have been acquired and installed.

Now, I'm working to migrate to the new machine. 3 1/2 years ago when I started futzing with Docker, I sorta followed guides and guessed, abused it trying to make it do things it wasn't designed for, and flipped switches I likely shouldn't have flipped, so the set up is more than a little shabby.

As a result, I'll likely end more redeploying than migrating the containers.

So rather than go forward with Docker blindly, I want to reassess whether I shouldn't look into Proxmox, LXC, or Podman instead of Docker, or maybe something else entirely?

Work is just about done dumping ESX for Nutanix, but both of those seem overkill for my needs.

Of course the forums for any of the solutions make their own out to be the best thing since sliced bread and the others useless, so I'm hoping to get a more nuanced answer here.

I’m looking at Opnsense on an Incus VM soon, what was your fight there? Good to know what I’ll hit ;)

Agreed on that path - some networking (like mimicking proxmox’s bridge connections which give VMs their own MAC/IP) takes effort to find the solution. But the basic LXC/VM-shares-your-IP works super easily and the script ability is great. Plus it doesn’t feel like a yoke on your system that is heavy and drives it, but just another application! I feel it’s close enough, and when you get it where you want it, it’s perf. I assume they’ll get “one click” solutions for the harder stuff baked in as they get more attention and traction.

"Just" some highly specific VM settings, in the end. I don't know much about that, and terms like qemu don't mean anything to me so I followed blog posts until it worked. (This one and maybe this one, I think.) It's possible that it is actually trivial.

It's been a while, but I can look up what I have when you need it. Feel free to ping me!

Yes, it was exactly that: Once I got the NICs set up the way I wanted them it was a breeze and everything just works. And I really like that I made every part work myself, no magic. I learned a lot, and wouldn't have had I relied on Proxmox fiddling with the right parts for me.

Thanks for the links! I had no idea there were special settings needed
