How to monitor Harbor registry with Prometheus metrics

In this blog post, we are going to explain how to monitor Harbor container registry with Prometheus metrics.

Although many of us typically use hosted container registries such as DockerHub, Quay, ECR, GCR, or ACR, when you need a self-hosted registry, Harbor is a great choice. Harbor provides great features such as RBAC, replication, and image scanning.
