= Enabling the cluster capabilities by setting additional enabled capabilities
|
|
|
|
As a cluster administrator, you can enable cluster capabilities any time after a {product-title} installation by setting the `additionalEnabledCapabilities` configuration parameter.
|
|
|
|
.Prerequisites
|
|
|
|
* You have installed the {oc-first}.
|
|
|
|
.Procedure
|
|
|
|
. View the additional enabled capabilities by running the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc get clusterversion version -o jsonpath='{.spec.capabilities.additionalEnabledCapabilities}{"\n"}'
|
|
----
|
|
+
|
|
.Example output
|
|
[source,terminal]
|
|
----
|
|
["openshift-samples"]
|
|
----
|
|
|
|
. To set the `additionalEnabledCapabilities` configuration parameter, run the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc patch clusterversion/version --type merge -p '{"spec":{"capabilities":{"additionalEnabledCapabilities":["openshift-samples", "marketplace"]}}}'
|

|
[IMPORTANT]
|
|
====
|
|
It is not possible to disable a capability which is already enabled in a cluster. The cluster version Operator (CVO) continues to reconcile the capability which is already enabled in the cluster.
|
|
====
|
|
|
|
|
|
If you try to disable a capability, then CVO shows the divergent spec:
|
|
[source,terminal]
|
|
----
|
|
$ oc get clusterversion version -o jsonpath='{.status.conditions[?(@.type=="ImplicitlyEnabledCapabilities")]}{"\n"}'
|
|
----
|
|
|
|
.Example output
|
|
[source,terminal]
|
|
----
|
|
{"lastTransitionTime":"2022-07-22T03:14:35Z","message":"The following capabilities could not be disabled: openshift-samples","reason":"CapabilitiesImplicitlyEnabled","status":"True","type":"ImplicitlyEnabledCapabilities"}
|

|
[NOTE]
|
|
====
|
|
During the cluster upgrades, it is possible that a given capability could be implicitly enabled. If a resource was already running on the cluster before the upgrade, then any capabilities that is part of the resource will be enabled. For example, during a cluster upgrade, a resource that is already running on the cluster has been changed to be part of the `marketplace` capability by the system. Even if a cluster administrator does not explicitly enabled the `marketplace` capability, it is implicitly enabled by the system.
