• 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.

docker-credential-vsphere login --user username@domain.com

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:

docker tag [:TAG] //[:TAG]

For example:

docker tag hello-world:latest 10.179.145.77/tkgs-cluster-ns/hello-world:latest

docker images

REPOSITORY TAG IMAGE ID CREATED SIZE

10.179.145.77/tkgs-cluster-ns/hello-world latest bf756fb1ae65 10 months ago 13.3kB

hello-world latest bf756fb1ae65 10 months ago 13.3kB

To push an image to a project in Harbor, run the following command:Syntax:

docker push //

For example:

docker push 10.179.145.77/tkgs-cluster-ns/hello-world:latest

Expected result.

The push refers to repository [10.179.145.77/tkgs-cluster-ns/hello-world]

Prerequisites

Configure a cluster with vSphere with Tanzu.

Create users or groups for all DevOps engineers who will access the namespace.

Create storage policies for persistent storage. Storage policies can define different types and classes of storage, for example, gold, silver, and bronze.

Create VM classes and content libraries for stand-alone VMs.

Create a content library for Tanzu Kubernetes releases for use with Tanzu Kubernetes clusters. See Creating and Managing Content Libraries for Tanzu Kubernetes releases.

Required privileges:

Namespaces.Modify cluster-wide configuration

Namespaces.Modify namespace configuration

NCP provides the following functionalities:

Automatically creates an NSX-T Data Center logical topology for a Kubernetes cluster, and creates a separate logical network for each Kubernetes namespace.

Implements Kubernetes Ingress with NSX-T layer 7 load balancer

Connects Kubernetes pods to the logical network, and allocates IP and MAC addresses.

Supports network address translation (NAT) and allocates a separate SNAT IP for each Kubernetes namespace.Note:When configuring NAT, the total number of translated IPs cannot exceed 1000.

Implements Kubernetes network policies with NSX-T Data Center distributed firewall.

Implements Kubernetes service of type ClusterIP and service of type LoadBalancer.

To connect to the Supervisor Cluster, run the following command.

kubectl vsphere login --server=SUPERVISOR-CLUSTER-CONTROL-PLANE-IP

--tanzu-kubernetes-cluster-name TANZU-KUBERNETES-CLUSTER-NAME

--tanzu-kubernetes-cluster-namespace SUPERVISOR-NAMESPACE-WHERE-THE-CLUSTER-IS-DEPLOYED

--vsphere-username VCENTER-SSO-USER-NAME

For example:

kubectl vsphere login --server=10.92.42.137

--tanzu-kubernetes-cluster-name tanzu-kubernetes-cluster-01

--tanzu-kubernetes-cluster-namespace tanzu-ns-1

--vsphere-username administrator@example.com
