I run a small server with Proxmox, and I'm wondering what are your opinions on running Docker in separate LXC containers vs. running a specific VM for all Docker containers?

I started with LXC containers because I was more familiar with installing services the classic Linux way. I later added a VM specifically for running Docker containers. I'm thinking if I should continue this strategy and just add some more resources to the docker VM.

On one hand, backups seem to be easier with individual LXCs (I've had situations where I tried to update a Docker container but the new container broke the existing configuration and found it easiest just to restore the entire VM from backup). On the otherhand, it seems like more overhead to install Docker in each individual LXC.

You dont need or want docker on your vm host. But a bare metal docker host can solve many peoples needs.

What in the world are you talking about? It's literally the entire point of containers orchestration systems, and the reason why you don't run containers inside containers. It's makes zero sense.
