We have the following use case:
- Nexus Repository server storing all Docker images.
- K8s cluster in VMWare Tanzu environment
- Harbor Docker registry server in VMWare Tanzu environment
Goal: Deployments in K8s should pull Docker images from the Harbor server.
As the Harbor server is ‘near’ the cluster, the downloads from there onto the pods should be fast.
Current challenge: How to connect Harbor with Nexus Repository?
In Harbor, we created a proxy cache project with a corresponding replication endpoint pointing at a Docker repo in Nexus. Nevertheless, Harbor CANNOT establish the connection!
