<p>A namespace is deleted and all containers in the namespace are lost.
I run command <code>history | grep delete</code>, but didn't get any namespace delete history.</p>

<p>Could anyone help find the delete reason? Thanks!</p>

<p>If you have enabled <a href="https://kubernetes.io/docs/tasks/debug-application-cluster/audit/" rel="nofollow noreferrer">auditing</a> of all requests to Kubernetes API Server on the kubernetes cluster then you could find out who submitted the delete request to delete the namespace and when.Audting is a recommended best practice to find out this kind of information in a production cluster.</p>
