Registry Proxy Architecture ​
Administrator configures Cloud Connector (Cloud-to-on-prem) between SAP BTP subaccount and the on-premise Docker registry.
Administrator configures the Connection custom resource.
The Application Developer reads the Connection status, configures the image pull secret, and schedules a Kubernetes workload from a container image.
The Kubernetes container runtime pulls image request routes through a managed NodePort and reverse-proxy Pod to reach the on-premise Docker registry using the Connectivity Proxy service.
