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.

    Snapshotting in docker is as easy as docker commit. After that you can back it up with docker save. Then move to another host, but not without downtime.

    However normally you need to backup/move only volumes attached to containers. If that’s not the way how you like to organize your services, you likely don’t need docker.
