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

vSphere Pods are only supported on Supervisor Clusters that use NSX-T Data Center as their networking stack.

Resource Management. vSphere DRS handles the placement of vSphere Pods on the Supervisor Cluster.

A dedicated IP range for virtual IPs. The HAProxy VM must be the only owner of this virtual IP range. The range must not overlap with any IP range assigned to any Workload Network owned by any Supervisor Cluster.

• 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]

For some parts of your application (for example, frontends) you may want to expose a Service onto an external IP address, that's outside of your cluster.

Kubernetes ServiceTypes allow you to specify what kind of Service you want. The default is ClusterIP.

A Supervisor Cluster namespace is a combination of resource allocations and permissions set within the Supervisor Cluster. When you create a Supervisor Namespace, you’ll assign who has access to use it, and how many of the ESXi cluster’s resources you can use (much like a resource pool).

When you enabled the Workload Management components, you created a special Kubernetes cluster called the “Supervisor Cluster”. You can continue to deploy virtual machines in this cluster, and you can also deploy kubernetes pods as a “pod vm” which is basically a container with some special wrapping so they are better isolated, like a virtual machine is.
