Kubernetes Event Disappears After 60mins

Problem

• Kubernetes Event Disappears After 60mins

• Storing Kubernetes Events Persistently

Environment

• Platform9 Managed Kubernetes - All Versions

Answer

• By default, Kubernetes events have a life span of 1-hour duration for easing the burden on ETCD, which is noted in this upstream feature request. This default value of 1 hour is customizable with kube-apiserver flag --event-ttl <duration> flag.

• To persistently store events, there are upstream projects like Eventrouter. But note that this project is not directly maintained by Platform9.
