Supervisor with "VDS + FLB"

This section describes the procedures for deploying a K8s Cluster in a Namespace utilizing a "VDS + FLB" architecture inside a vSphere environment.

• K8s Cluster
  • Deployment via CLI
  • Access via CLI

K8s Cluster Access

Client Operating System

While the command outputs below are captured from a Windows client, the vcf and kubectl CLI tools operate identically across Linux and macOS environments.

Connect to K8s Cluster

Retrieve K8s Kubeconfig file

Create the K8s Cluster kubeconfig file "my-cluster-kubeconfig.yaml".

[System.IO.File]::WriteAllBytes("$pwd\my-cluster-kubeconfig.yaml", [System.Convert]::FromBase64String((kubectl get secret my-cluster-kubeconfig -n demo-space -o jsonpath='{.data.value}')))

Output example

PS C:\Users\Administrator\Documents> [System.IO.File]::WriteAllBytes("$pwd\my-cluster-kubeconfig.yaml", [System.Convert]::FromBase64String((kubectl get secret my-cluster-kubeconfig -n demo-space -o jsonpath='{.data.value}')))

Connect to the K8s Cluster

• Create KUBECONFIG variable

  $env:KUBECONFIG="$pwd\my-cluster-kubeconfig.yaml"
  

  Output example

  PS C:\Users\Administrator\Documents> $env:KUBECONFIG="$pwd\my-cluster-kubeconfig.yaml"
  

  Note: To connect back to the Supervisor Namespace (such as "demo-space")

  PS C:\Users\Administrator\Documents> $env:KUBECONFIG = $null
  

• Change context to my K8s Cluster

  kubectl config use-context my-cluster-admin@my-cluster
  

  Output example

  PS C:\Users\Administrator\Documents> kubectl config use-context my-cluster-admin@my-cluster
  Switched to context "my-cluster-admin@my-cluster".

Validate Namespace Access

Validate Context is the K8s Cluster

kubectl config get-contexts

Output example

The current context is:
. Cluster: my-cluster
. Namespace: default (empty)

PS C:\Users\Administrator\Documents> kubectl config get-contexts
CURRENT   NAME                          CLUSTER      AUTHINFO           NAMESPACE
*         my-cluster-admin@my-cluster   my-cluster   my-cluster-admin

Validate K8s Cluster connection

kubectl get nodes

Output example

PS C:\Users\Administrator\Documents> kubectl get nodes
