= Enabling feature sets using the CLI
|
|
|
|
[role="_abstract"]
|
|
You can use the {oc-first} to enable feature sets for all of the nodes in a cluster by editing the `FeatureGate` custom resource (CR). Completing this task enables non-default features in your cluster.
|
|
|
|
.Prerequisites
|
|
|
|
* You have installed the {oc-first}.
|
|
|
|
.Procedure
|
|
|
|
* Edit the `FeatureGate` CR named `cluster`:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc edit featuregate cluster
|
|
----
|
|
+
|
|
[WARNING]
|
|
====
|
|
Enabling the `TechPreviewNoUpgrade` feature set on your cluster cannot be undone and prevents minor version updates. You should not enable this feature set on production clusters.

.Sample FeatureGate custom resource
|
|
[source,yaml]

apiVersion: config.openshift.io/v1
|
|
kind: FeatureGate
|
|

After you save the changes, new machine configs are created, the machine config pools are updated, and scheduling on each node is disabled while the change is being applied.
