Kured - Kubernetes Reboot Daemon

Kured (KUbernetes REboot Daemon) is a Kubernetes daemonset that performs safe automatic node reboots when the need to do so is indicated by the package management system of the underlying OS.

Watches for the presence of a reboot sentinel file e.g. /var/run/reboot-required or the successful run of a sentinel command.

Utilises a lock in the API server to ensure only one node reboots at a time.

Optionally defers reboots in the presence of active Prometheus alerts or selected pods.

Cordons & drains worker nodes before reboot, uncordoning them after.

Kured is a Cloud Native Computing Foundation Sandbox project.
