What is proxmox-qdevice?

This Shell-based Docker container runs a Corosync QDevice for Proxmox VE clusters, delivering an external vote to prevent split-brain in two-node setups or tiebreakers in even-sized ones. Deploy it via docker compose up -d or docker run on any host, feeding Proxmox node IPs and SSH creds through env vars for auto-setup—no third physical node needed. Pull pre-built images from GitHub Container Registry, built automatically via docker github actions.

Why is it gaining traction?

It stands out with one-command auto-config over Proxmox nodes, preserving certs in a volume for seamless docker container updaten via docker compose pull && up -d. Check status with docker container logs or pvecm status; restart with docker container neu starten if needed. Multi-arch support (amd64/arm64) and GitHub Actions caching make it dead simple for docker github registry pulls versus manual corosync-qnetd installs.

Who should use this?

Proxmox admins managing two-node homelabs or small prod clusters prone to quorum loss during outages. Ideal for NAS owners docker container erstellen a lightweight arbiter without dedicated hardware, or teams dodging manual pvecm qdevice setup across nodes.

Verdict

Solid docs and docker container list-friendly Compose files make it usable out-of-box, but 10 stars and 1.0% credibility score signal early-stage maturity—test thoroughly in non-prod first. Grab it for quick proxmox qdevice docker wins if you're already in the ecosystem.
