= Understanding feature gates and Technology Preview features
|
|
|
|
You can use the Feature Gate Custom Resource to enable Technology Preview
|
|
features throughout your cluster. This allows you, for example, to enable
|
|
Technology Preview features on test clusters where you can fully test them while
|
|
ensuring they are disabled on production clusters.
|
|
|
|
[IMPORTANT]
|
|
====
|
|
After turning Technology Preview features on using feature gates, they cannot be
|
|
turned off and cluster upgrades are prevented.

If you disable a feature that appears in the web console, you might see that feature, but
|
|
no objects are listed. For example, if you disable builds, you can see the *Builds* tab in the web console, but there are no builds present.
|
|
|
|
If you attempt to use commands associated with a disabled feature, such as `oc start-build`, {product-title}
|
|
displays an error.
|
|
|
|
[NOTE]
|
|
====
|
|
If you disable a feature that any application in the cluster relies on, the application might not
|
|
function properly, depending upon the feature disabled and how the application uses that feature.
