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.
