Postinstallation configuration
The following procedures are typically performed after OpenShift Virtualization is installed. You can configure the components that are relevant for your environment:
-
Node placement rules for OpenShift Virtualization Operators, workloads, and controllers
-
-
Enabling the creation of load balancer services by using the Red Hat OpenShift Service on AWS web console
-
-
-
Defining a default storage class for the Container Storage Interface (CSI)
-
Configuring local storage by using the Hostpath Provisioner (HPP)
-
