Web Portal

The Web Portal is a graphical user interface designed to help users manage images within the Registry. To ensure scalability and redundancy, it is deployed as a ReplicaSet, with a single instance in an All-in-One deployment and multiple instances in a Highly Available (HA) setup. These replicas are not quorum-based, meaning there are no limits on the number of replicas. The instance count should be determined by your specific use case and load requirements. To ensure high availability, it is recommended to have at least two replicas.
