Deprecation

This chart is deprecated! It has been moved to the kured repository. See https://github.com/weaveworks/kured/tree/master/charts/kured for details.

Autolock feature

This feature is not natively supported by kured but is added using Kubernetes Cronjob to annotate daemonset when to allow kured to run using the lock configuration annotation https://github.com/weaveworks/kured#overriding-lock-configuration

Prometheus Metrics

Kured exposes a single prometheus metric indicating whether a reboot is required or not (see kured docs) for details. It can be scraped with the following set of annotations:

podAnnotations:
  prometheus.io/scrape: "true"
  prometheus.io/path: "/metrics"
  prometheus.io/port: "8080"
