• VM storage policies are translated into Kubernetes storage classes.

• Developers can access all assigned VM storage policies in the form of storage classes. •

Developers cannot manage storage classes.

The container network interfaces (CNIs) supported with Tanzu Kubernetes clusters created by the Tanzu Kubernetes Grid Service are NSX-T and Antrea. NSX-T is a multi-cloud networking and security platform from VMware that provides built-in container networking and security capabilities. Antrea is an open-source CNI project created by the GitHub team that provides network policy enforcement for Kubernetes clusters. Both of these CNIs provide support for multi-tenancy and advanced network policy enforcement.

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

If you want to control traffic flow at the IP address or port level (OSI layer 3 or 4), then you might consider using Kubernetes NetworkPolicies for particular applications in your cluster. NetworkPolicies are an application-centric construct which allow you to specify how a pod is allowed to communicate with various network "entities" (we use the word "entity" here to avoid overloading the more common terms such as "endpoints" and "services", which have specific Kubernetes connotations) over the network. NetworkPolicies apply to a connection with a pod on one or both ends, and are not relevant to other connections.

External HTTP(S) Load Balancing is a proxy-based Layer 7 load balancer that enables you to run and scale your services behind a single external IP address.

You can deploy an application on a namespace on a Supervisor Cluster. Once the application is deployed, the respective number of vSphere Pods are created on the Supervisor Cluster within the namespace.

Common kubectl commands include the apply, get, describe, and delete commands:

• The kubectl apply command applies the contents of a YAML file. Typically, this command is used to create a pod or deployment: —

kubectl apply -f /path/to/my.yaml

• The kubectl get command returns basic information about an object: — kubectl get pod

Create an example pod spec with the details about the private registry.

apiVersion: v1

kind: Pod

- name: private-reg-container

Replace  with the name of the pod workload.

Replace  with the Kubernetes namespace in the cluster where the pod will be created. This must be the same Kubernetes namespace where the Registry Service image pull secret is stored in the Tanzu Kubernetes cluster (such as the default namespace).

Replace  with the IP address for the embedded Harbor Registry instance running on the Supervisor Cluster.

Replace with the vSphere Namespace where the target Tanzu Kubernetes is provisioned.

Replace  with an image name of your choice.

Replace  with an appropriate version of the image, such as "latest".

Replace  with the name of the Registry Service image pull secret that you created previously.
