Kubereboot/Kured: Kubernetes Reboot Daemon

Source: Hacker News

Introduction

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, and uncordons them after.
