VMs or containers? (lemmy.world)

I'm thinking about starting a self hosting setup, and my first thought was to install k8s (k3s probably) and containerise everything.

But I see most people on here seem to recommend virtualizing everything with proxmox.

What are the benefits of using VMs/proxmox over containers/k8s?

Or really I'm more interested in the reverse, are there reasons not to just run everything with k8s as the base layer? Since it's more relevant to my actual job, I'd lean towards ramping up on k8s unless there's a compelling reason not to.

I personally really, really like (Docker) containers and I host most of my stuff with it, on a Raspberry Pi and on (free tier) Oracle Cloud VPS's. I also plan to (re)install Proxmox on a spare old laptop and run some stuff in VMs on that (namely Home Assistant) and might try a NixOS server too.

So really, use both. Use the right tool for the job. And you can also run containers in VMs and even use Ansible to configure everything with playbooks, allowing you to re-run said playbooks when things go wrong.
