5V0-23.20 Dumps with Practice Exam Questions Answers

As a vSphere administrator, you can replace the certificate for the virtual IP address (VIP) to securely connect to the Supervisor Cluster API endpoint with a certificate signed by a CA that your hosts already trust. The certificate authenticates the Kubernetes control plane to DevOps engineers, both during login and subsequent interactions with the Supervisor Cluster.

Prerequisites

Verify that you have access to a CA that can sign CSRs. For DevOps engineers, the CA must be installed on their system as a trusted root.

Procedure

• In the vSphere Client, navigate to the Supervisor Cluster.
• Click Configure then under Namespaces select Certificates.
• In the Workload platform MTG pane, select Actions > Generate CSR.
• Provide the details for the certificate.
• Once the CSR is generated, click Copy.
• Sign the certificate with a CA.
• From the Workload platform MTG pane, select Actions > Replace Certificate.
• Upload the signed certificate file and click Replace Certificate.
• Validate the certificate on the IP address of the Kubernetes control plane.

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

Creating a Namespace

A vSphere administrator configures permissions and storage before a namespace can be used:

• Assign edit or view permissions to users. Users must be present in a configured single sign-on (SSO) identity source.

• Must assign a VM storage policy to the namespace.

• Can define resource limits (optional).

• Must add a content library to enable the Tanzu Kubernetes Grid Service.

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
