Learn to interact with your Kubernetes cluster

This guide explains how to use the command line to interact with your newly deployed Kubernetes cluster.

Before you start, make sure you have created a workload cluster, as described in Create a New Cluster.

Explore the new Kubernetes cluster

  1. Get a kubeconfig file for the workload cluster:

    When the workload cluster is created, the cluster lifecycle services generate a kubeconfig file for the workload cluster, and write it to a Secret. The kubeconfig file is scoped to the cluster administrator.

    Get the kubeconfig from the Secret, and write it to a file, using this command:

    dkp get kubeconfig -c ${CLUSTER_NAME} > ${CLUSTER_NAME}.conf
    CODE

  2. List the Nodes using this command:

    kubectl --kubeconfig=${CLUSTER_NAME}.conf get nodes
    CODE
    NAME                                STATUS   ROLES                  AGE     VERSION
    azure-example-control-plane-7ffnl   Ready    control-plane,master   6m18s   v1.22.7
    azure-example-control-plane-l4bv8   Ready    control-plane,master   14m     v1.22.7
    azure-example-control-plane-n4g4l   Ready    control-plane,master   18m     v1.22.7
    azure-example-md-0-mpctb            Ready    <none>                 15m     v1.22.7
    azure-example-md-0-qglp9            Ready    <none>                 15m     v1.22.7
    azure-example-md-0-sgrd6            Ready    <none>                 16m     v1.22.7
    azure-example-md-0-wzbkl            Ready    <none>                 16m     v1.22.7
    CODE


NOTE: It may take a few minutes for the Status to move to Ready while the Pod network is deployed. The Nodes’ Status should change to Ready soon after the calico-node DaemonSet Pods are Ready.

3. List the Pods using this command:

kubectl --kubeconfig=${CLUSTER_NAME}.conf get --all-namespaces pods
