installer does not parse and include the "mirrorSourcePolicy" field under imageDigestSources. This means that we cannot use the "mirrorSourcePolicy: NeverContactSource" setting that IDMS support.

    1. Add The following to an install-config.yaml

imageDigestSources:
- mirrors:
  - private.registry.io:5000/openshift
  source: quay.io/openshift-release-dev/ocp-release
  mirrorSourcePolicy: NeverContactSource


    2. Generate manifests with the command: openshift-install generate manifests --dir=/path/to/installconfig
    3.
    

    openshift-installer has a 0 return code but with the following warning message "WARNING failed to parse first occurrence of unknown field: failed to unmarshal install-config.yaml: error unmarshaling JSON: while decoding JSON: json: unknown field "mirrorSourcePolicy""

    The installer also does not add those fields to the manifest file idms_testing/manifests/image-digest-mirror-set.yaml. We can see that it only has the mappings


apiVersion: config.openshift.io/v1
kind: ImageDigestMirrorSet
metadata:
  creationTimestamp: null
  name: image-digest-mirror
spec:
  imageDigestMirrors:
  - mirrors:
    - private.registry.io:5000/openshift
    source: quay.io/openshift-release-dev/ocp-release
  - mirrors:
    - private.registry.io:5000/openshift
    source: quay.io/openshift-release-dev/ocp-v4.0-art-dev
status: {}

    The installer will parse and include the "mirrorSourcePolicy" field, supported by ImageDigestMirrorSet, when included in the install-config.yaml

We have run into a bunch of situations where contacting the original source causes issues if someone has taken over quay.io on a private network and is pointing it to some other registry which is not the private registry that the customer is using.
