Proxmox cluster service running in container

Hi all,

I have a two-node Proxmox cluster (on-board storage, no Ceph) that I use to run VMs for testing and development purposes. I don't have extra hardware to install a third node so that quorum decisions are handled better when something goes wrong, like today when one of my nodes had trouble with its networking.

I do, however, have a QNAP NAS that can run LXC and Docker containers.

I was wondering - has anyone ever tried putting the Proxmox components into a container so that it could run on a NAS device and act as a cluster member for purposes of quorum as well as possibly handling the web interface aspect as well?

Thanks in advance,
- Matt

The proxmox components do not run in LXC or docker directly, because you need fuse for /etc/pve. For the quorum service, you do not need all (even if any) proxmox components, because the quorum is provided by corosync: https://pve.proxmox.com/wiki/Cluster_Manager#_corosync_external_vote_support

i don't know if anyone managed to do that before, but for a qdevice, proxmox components are not necessary. you just need the appropriate corosync packages (and the corosync versions need to match, so if you're on pve 6, you need corosync 3).

check our documentation (linked above by @LnxBil) for more info
