In this doc we give the step to mirror the relevant images but we're missing 2 things:

1) INDEX_IMG=something

2) the command (probably "ocm index add") to actually create the index

1. Create the openstack namespace:
    
   $ oc new-project openstack
2. Create the index image and push it to your registry:
    
    
   $ podman login registry.redhat.io
   $ podman login your.registry.local
   $ BUNDLE_IMG="registry.redhat.io/rhosp-rhel8/osp-director-operator-bundle@sha256:c19099ac3340d364307a43e0ae2be949a588fefe8fcb17663049342e7587f055"
   Note
   You can get the latest bundle image from: Certified container images. Search for osp-director-operator-bundle.

1. Mirror the relevant images based on the operator index image:
    
    
   $ oc adm catalog mirror ${INDEX_IMG} your.registry.local --insecure --index-filter-by-os='Linux/x86_64'
2.
