1)  Use following imagesetconfig :
cat config.yaml 
kind: ImageSetConfiguration
apiVersion: mirror.openshift.io/v1alpha2
mirror:
  operators:
    - catalog: registry.redhat.io/redhat/redhat-operator-index:v4.15
      packages:
        - name: devworkspace-operator
          minVersion: "0.23.0"
        - name: quay-operator
          maxVersion: "3.10.2"
        - name: cluster-logging
          minVersion: 5.8.3
          maxVersion: 5.8.5

2)  Do mirror2Disk and disk2Mirror : 
`oc-mirror --config config.yaml file://outnochannel --v2`
`oc-mirror --config config.yaml --from file://outnochannel --v2 docker://ec2-3-17-164-23.us-east-2.compute.amazonaws.com:5000/default`
   
3) Create the catalogsource, idms, itms resources

4) failed to create ImageTagMirrorSet
oc create -f outnochannel/working-dir/cluster-resources/idms-oc-mirror.yaml
