Temporary "openshift-debug-node" namespaces do not get deleted properly after "oc debug node" in Openshift Container Platform 4.

Solution Verified - Updated

Environment

  • Red Hat Openshift Container Platform (RHOCP)
    • 4

Issue

  • After issuing an oc debug node/<nodename>, the created namespaces are not getting deleted properly and automatically.

Resolution

  • Automatic deletion was fixed in Openshift Container platform 4.6.28+ and Openshift Container platform 4.7.8+

  • The namespaces can be deleted manually:

    $ oc delete namespace <debug-namespace>

  • Multiple namespaces can be deleted at once manually:

    • To get the list of all debug namespaces in cluster:
    $ oc get $(oc get -o name namespaces | grep 'namespace/openshift-\(debug\)')
    • To delete all the debug namespaces in cluster:
    $ oc delete $(oc get -o name namespaces | grep 'namespace/openshift-\(debug\)')
