In OpenShift Container Platform (OCP) 4, most of the functionality is controlled by Operators. To see the currently installed Operators and also their status, use the following command:

$ oc get clusteroperators

You can find the description of the default Operators in the documentation.

This will only list the Red Hat Operators that are installed as part of the cluster. These are all controlled by the ClusterVersionOperator, which is the “Master-Operator” of the cluster controlling all others.

If you want to list all Operators that were installed via the Operator Lifecycle Manager (OLM), you can use the following command:

$ oc get subscriptions --all-namespaces
