Red Hat Summit4.11. Enabling Technology Preview features using FeatureGates
You can turn on a subset of the current Technology Preview features on for all nodes in the cluster by editing the FeatureGate custom resource (CR).
4.11.1. Understanding feature gates
You can use the FeatureGate custom resource (CR) to enable specific feature sets so that you can use specific non-default features in your cluster.
A feature set is a collection of OpenShift Container Platform features that are not enabled by default.
You can activate the following feature set by using the FeatureGate CR:
TechPreviewNoUpgrade. This feature set is a subset of the current Technology Preview features. This feature set allows you to enable these Technology Preview features on test clusters, where you can fully test them, while leaving the features disabled on production clusters.주의Enabling the
TechPreviewNoUpgradefeature set on your cluster cannot be undone and prevents minor version updates. You should not enable this feature set on production clusters.The following Technology Preview features are enabled by this feature set:
