= Enabling feature sets using the web console
|
|
|
|
[role="_abstract"]
|
|
You can use the {product-title} web console 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.
|
|
|
|
.Procedure
|
|
|
|
. In the {product-title} web console, switch to the *Administration* -> *Custom Resource Definitions* page.
|
|
|
|
. On the *Custom Resource Definitions* page, click *FeatureGate*.
|
|
|
|
. On the *Custom Resource Definition Details* page, click the *Instances* tab.
|
|
|
|
. Click the *cluster* feature gate, then click the *YAML* tab.
|
|
|
|
. Edit the *cluster* instance to add specific feature sets:
