VMware Harbor Registry

VMware Harbor Registry is an enterprise-class registry server that stores and distributes container images. Harbor allows you to store and manage images for use with VMware Tanzu Kubernetes Grid Integrated Edition (TKGI).

Overview

Harbor extends the open source Docker Distribution by adding the functionalities usually required by an enterprise, such as security, identity, and management. As an enterprise private registry, Harbor offers enhanced performance and security. Deploying a registry alongside the TKGI environment improves image management efficiency.

• Registry Service: Developers can store and manage Docker and OCI images using Harbor. Harbor is an open-source container image registry that secures images with role-based access control.

Procedure

• Login to Harbor Registry with the vSphere Docker Credential Helper.

Note:While providing --user username is acceptable for login, you should use the UserPrincipalName (UPN) syntax ( --user username@domain.com) to login and use docker push commands.

• Tag the image that you want to push to the project in Harbor Registry with same name as the namespace, where you want to use it:

For example:

• uk.co.certification.simulator.questionpool.PList@35c9b420
• To push an image to a project in Harbor, run the following command:Syntax:

For example:

• uk.co.certification.simulator.questionpool.PList@35c9b4f0

Expected result.

• uk.co.certification.simulator.questionpool.PList@35c9b530

The Supervisor Cluster provides the management layer on which Tanzu Kubernetes clusters are built. The Tanzu Kubernetes Grid Service is a custom controller manager with a set of controllers that is part of the Supervisor Cluster. The purpose of the Tanzu Kubernetes Grid Service is to provision Tanzu Kubernetes clusters.

While there is a one-to-one relationship between the Supervisor Cluster and the vSphere cluster, there is a one-to-many relationship between the Supervisor Cluster and Tanzu Kubernetes clusters. You can provision multiple Tanzu Kubernetes clusters within a single Supervisor Cluster. The workload management functionality provided by the Supervisor Cluster gives you control over the cluster configuration and lifecycle, while allowing you to maintain concurrency with upstream Kubernetes.

A user can have permissions on multiple namespaces. The kubectl commands are typically actioned against the current active namespace.

View the list of available namespaces:

kubectl config get-contexts

Change the current active namespace:

kubectl config use-context

The storage policy would become a storage class in Kubernetes.
