Default service settings for Red Hat OpenShift components
Review the default settings for Red Hat OpenShift components in your Red Hat® OpenShift® on IBM Cloud® clusters.
Feature gates
Review the feature gates that are applied to all master and worker node components by default in Red Hat OpenShift on IBM Cloud clusters. These feature gates differ from the ones that are set up in community distributions. Most new beta features
are disabled by default. Red Hat OpenShift alpha features, (also known as developer or technology preview features) which are subject to change, are disabled. In clusters that run version 4.14 or later, the oc get featuregate cluster -o yaml command can be used to view the cluster feature gate specification and status.
Modifying feature gates is not supported in Red Hat OpenShift on IBM Cloud.

Global settings
Because Red Hat OpenShift on IBM Cloud is a managed service, many OpenShift Container Platform global settings are set up for you. You can configure some global settings, but other global settings you can only review, and any changes are overwritten. For more information, see Comparison between clusters that run in IBM Cloud and standard OCP. You can also review the control plane components in the Red Hat OpenShift on IBM Cloud Toolkit project on GitHub.
Configurable global settings:
