Juniper is aware of a condition where changing the registry location of an existing deployment will trigger a full redeploy of all containers in the cluster. We are actively working to restore access via the old container registry location to remove the requirement for this change and resolve issues during upgrades and expansions.


Starting with the 22.3 release, the containers needed for CN2 are posted to our new container registry:  enterpise-hub.juniper.net. Over the next few weeks, we will move all previous releases of Contrail Networking and CN2 to this repository and will be deprecating hub.juniper.net by October 15th.  
                                                                                     
Contact customer care to open a ticket requesting access to enterprise-hub.juniper.net to access the Contrail Networking container repository.

Technical Note:
The registry path (namespace) must be changed:
Old path:  hub.juniper.net/contrail
New path: enterprise-hub.juniper.net/contrail-container-prod
