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.
I used to use LXC, and switched to VM since internet said it was better.
I kinda miss the LXC setup. Day to day I don’t notice any difference, but increasing storage space in VM was a small pain compared to LXC. In VM I increased disk size through proxmox, but then I had to increase the partition inside VM.
In LXC you can just increase disk size and it immediately is available to the containers
