I recently installed proxmox on two 7050 micro pcs, and set up a third box with PBS.

Within proxmox is it best to run docker in a LXC or a VM ?

Should I run one docker image per instance, or all in the same instance ?

I would like to back this stuff up to PBS. Is this a factor in this decision?

I have plex, node-red, influxdb, mosquitto and grafana dockers on an old pc that I wish to rehost to proxmox.
