## What it is
Kured (KUbernetes REboot Daemon) is a Kubernetes daemonset that safely performs automatic node reboots when the underlying OS indicates one is required, e.g. via a reboot sentinel file. It coordinates reboots with an API-server lock so only one node reboots at a time, cordons and drains nodes before rebooting, and can defer reboots during active Prometheus alerts.

## Use cases
- automatically reboot kubernetes nodes after security patches
- apply OS updates requiring reboot across a kubernetes cluster safely
- drain and cordon nodes one at a time for reboots
- defer node reboots while prometheus alerts are firing
- detect reboot-required sentinel files on cluster nodes

## When to choose
- you run a Kubernetes cluster and want safe, serialized automatic node reboots after OS updates
- you need cordon/drain handling and alert-aware reboot deferral built in
- you want a CNCF sandbox, Helm-installable daemonset with active maintenance

## When to avoid
- you are not running Kubernetes - kured only orchestrates reboots through the Kubernetes API
- you need full patch management or OS update installation, not just rebooting
- you want to reboot nodes outside a cluster-managed workflow or on non-Linux nodes
