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 configurationChoices.md), 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.
