Proxmox cluster service running in container

[ZipsterM]

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).
