Namespaces openshift-debug are not autodeleted after accessing to node terminal via OpenShift web console

Environment

• Red Hat Openshift Container Platform (RHOCP)
  • 4

Issue

• Temporary namespaces openshift-debug-xxxx, which are created when opening a terminal to the node via the OpenShift web console by navigating to Compute --> Nodes --> Select a node --> Terminal tab, are sometimes not getting auto deleted, leaving several namespaces behind.

Resolution

This is a known issue and a Request For Enhancement has been created for the Red Hat Engineering Team: Content from redhat.atlassian.net is not included.RFE-4008. The RFE has been accepted but not yet implemented, and the implementation can be tracked in Content from redhat.atlassian.net is not included.OCPSTRAT-2120.

Workaround

The openshift-debug namespaces left behind can be manually deleted. Before deleting them, ensure there are no running pods in any of the openshift-debug namespaces:

$ oc get pods -A | grep "openshift-debug"

Root Cause

When accessing to a terminal for a node via the OpenShift web console, a temporary 'openshift-debug-xxxx' namespace is created. Some times, those namespaces are not automatically deleted, depending on the way the connection to the terminal is terminated.

Diagnostic Steps

• For reproducing the issue, open a node terminal from the OpenShift web console by going to Compute --> Nodes --> Select a node --> Terminal tab. From the bastion host, or the machine used to run oc commands, check for openshift-debug projects using oc client:

  $ oc get ns | grep "openshift-debug"
  

  Then, close the terminal from the console and check the status of the namespace using oc client:

  $ oc get ns | grep "openshift-debug"
  

  Depending on how the connectivity to the terminal is lost, the namespace could be deleted or not.
