Technical Requirements for OpenShift

The OpenShift cluster on which you are deploying OpenWhisk must meet the following requirements:

  • OpenShift version 4.5 or newer (these instructions were tested on 4.5).
  • The ability to create Ingresses to make a Kubernetes service available outside of the cluster so you can actually use OpenWhisk.
  • Unless you disable persistence (see, either your cluster must be configured to support Dynamic Volume Provision and you must have a DefaultStorageClass admission controller enabled or you must manually create any necessary PersistentVolumes when deploying the Helm chart.
