QuorumKit
Deploy and operate production database clusters on your own servers, without Kubernetes.
QuorumKit is a self-hosted control plane for databases. You give it Linux servers with Docker; it gives you PostgreSQL, MySQL and MongoDB — highly available, backed up, monitored, and reachable at a stable address.
Install
One command on the machine that will run the control plane:
curl -fsSL https://quorumkit.subhamsaha.in/get | sudo shIt installs Docker if the host has none, writes /opt/quorumkit, and starts. When it finishes it
prints the console's address and the password it generated for the first sign-in.
What happens next
Sign in, create a project, and press Add server. The console prints a command to run on each machine you want in the fleet; every agent connects outward to the control plane, so the servers need no inbound access beyond the ports the databases themselves publish.
Nothing is applied without a plan
Every change is previewed — the exact containers, files, firewall rules and DNS records — and approved before anything touches a server.
A backup that has not restored is unverified
Chains are checked for integrity and restore-drilled into a throwaway sandbox. Until one passes, the console says so.
