Registry

The Harbor Registry is deployed as a ReplicaSet, running as a single instance in All-in-One deployments and supporting multiple replicas in HA mode. 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. Like the Job Service, it utilizes a PVC to store registry data, using either local or shared backend storage. For more details on storage options, please refer to the Storage section. The Registry workload relies on a ConfigMap to store the config.yaml and uses Secrets to manage sensitive parameters, such as keys and passwords.
