1.skopeo copy --all --format v2s2 docker://icr.io/cpopen/ibm-zcon-zosconnect-catalog@sha256:6f02ecef46020bcd21bdd24a01f435023d5fc3943972ef0d9769d5276e178e76 oci:///home1/611/oci-index
2. change the work directory to :  `cd  home1/611/oci-index` 
3. run the oc-mirror command : 
cat config.yaml 
kind: ImageSetConfiguration
apiVersion: mirror.openshift.io/v1alpha2
storageConfig:
  local:
    path: /home1/ocilocalstorage
mirror:
  operators:
  - catalog: oci:///home1/611/oci-index

`oc-mirror --config config.yaml docker://ec2-18-217-58-249.us-east-2.compute.amazonaws.com:5000/multi-oci --dest-skip-tls --include-local-oci-catalogs`
4. apply the catalogsouce and ICSP yaml file;
5 . check the catalogsource pod 

[root@preserve-fedora36 oci-index]# oc get pod --show-labels
