The guide "DEPLOYING RED HAT PROCESS AUTOMATION MANAGER ON RED HAT OPENSHIFT CONTAINER PLATFORM" contains misleading information on the creation of the link to the service account. In section "2.1. Ensuring your environment is authenticated to the Red Hat registry", instead of:

oc secrets link default <secret_name> --for=pull

it should be:

oc secrets link <kieapp_name>-rhpamsvc <secret_name> --for=pull

These should be a configuration option to provide this further step automatically as part of the deployment (e.g., e operator should allow providing a pull secret)
