1)  Copy the operator as OCI format to localhost:
`skopeo copy --all docker://registry.redhat.io/redhat/redhat-operator-index:v4.15 oci:///app1/noo/redhat-operator-index --remove-signatures`

2)  Use following imagesetconfigure for mirror: cat config-multi-op.yaml 
kind: ImageSetConfiguration
apiVersion: mirror.openshift.io/v1alpha2
mirror:
  operators:
    - catalog: oci:///app1/noo/redhat-operator-index
      packages:
        - name: odf-operator
`oc-mirror --config config-multi-op.yaml file://outmulitop   --v2`


3) Do diskTomirror :
`oc-mirror --config config-multi-op.yaml --from file://outmulitop  --v2 docker://ec2-3-139-239-15.us-east-2.compute.amazonaws.com:5000/multi`

4) Create cluster resource with file: itms-oc-mirror.yaml
   `oc create -f itms-oc-mirror.yaml`

4) failed to create ImageTagMirrorSet
