If you are not familiar with the oc command, refer to OpenShift - Getting Started with the oc command.

There are a few similar commands that can be used to list each project / namespace in your OpenShift cluster.

• The oc get netnamespaces command
• The oc get namespaces command (this article)
• The oc get projects command

The oc get namespaces command can be used to return each project / namespace in your OpenShift cluster. Something like this should be returned.

 ~]$ oc get namespaces
NAME                             STATUS   AGE
my-project                       Active   4y117d
foo-project                      Active   4y117d
bar-namespace                    Active   4y117d
default                          Active   4y122d

The oc describe namespace command can be used to display details for a specific namespace.

~]$ oc describe namespace my-project
Name:         my-project
Labels:       kubernetes.io/metadata.name=my-project
              pod-security.kubernetes.io/audit=baseline
              pod-security.kubernetes.io/audit-version=v1.24
              pod-security.kubernetes.io/warn=baseline
              pod-security.kubernetes.io/warn-version=v1.24

Or the oc get namespace with the --output json or --output yaml option can be used.

~]$ oc get namespace my-project --output yaml
