1)  The following steps to simulate the enterprise registry : 
Launch cluster ,create registry app and configure the Registry Certificate as trusted for cincinnati
2) mirror with following imageconfigset :
kind: ImageSetConfiguration
apiVersion: mirror.openshift.io/v2alpha1
mirror:
  platform:
    graph: true
    channels:
    - name: stable-4.15
execute mirror2miror command : 
`oc-mirror -c config.yaml --workspace  file://outm2m --v2 docker://myregistry-zhouy.apps.yinzhou-27.qe.devcluster.openshift.com  --dest-tls-verify=false --retry-times 10`

3) On web console install the OSUS operator
4)  Create the osus cluster by the updateService.yaml (created by oc-mirror)  in the OSUS operator namespace


5) The following steps to simulate the enclave mirror 
 cat /etc/squid/squid.conf
http_port 3128
coredump_dir /var/spool/squid
acl whitelist dstdomain "/etc/squid/whitelist"
http_access allow whitelist
http_access deny !whitelist


cat /etc/squid/whitelist 
my-route-zhouy.apps.yinzhou-88.qe.devcluster.openshift.com                                    -------------registry route
update-service-oc-mirror-route-openshift-update-service.apps.yinzhou-88.qe.devcluster.openshift.com        ---osus route


export https_proxy=http://127.0.0.1:3128
export http_proxy=http://127.0.0.1:3128


`oc get updateservice update-service-oc-mirror -n openshift-update-service  -o jsonpath='{.status.policyEngineURI}'`
export UPDATE_URL_OVERRIDE=`oc get updateservice update-service-oc-mirror -n openshift-update-service  -o jsonpath='{.status.policyEngineURI}'`/api/upgrades_info/v1/graph


open the url for UPDATE_URL_OVERRIDE on browser , download the ca from brower and save it :
sudo cp /home/fedora/_.apps.yinzhou-88.qe.devcluster.openshift.com /etc/pki/tls/certs/
sudo  update-ca-trust

 Setting registry redirect with : 
cat ~/.config/containers/registries.conf 
[[registry]]
  location = "quay.io"
  insecure = false
  blocked = false
  mirror-by-digest-only = false
  prefix = ""
  [[registry.mirror]]
    location = "my-route-zhouy.apps.yinzhou-88.qe.devcluster.openshift.com"
    insecure = false


6) run the enclave mirror with command : 
./oc-mirror   -c config.yaml file://outenclave --v2

6) ./oc-mirror   -c config.yaml file://outenclave --v2 2024/09/27 07:03:19  [WARN]   : ⚠️  --v2 flag identified, flow redirected to the oc-mirror v2 version. This is Tech Preview, it is still under development and it is not production ready.
