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
    ip-10-0-100-85.us-west-2.compute.internal    Ready    <none>                 8m13s   v1.22.8
    ip-10-0-106-183.us-west-2.compute.internal   Ready    control-plane,master   6m22s   v1.22.8
    ip-10-0-158-104.us-west-2.compute.internal   Ready    control-plane,master   8m58s   v1.22.8
    ip-10-0-203-138.us-west-2.compute.internal   Ready    control-plane,master   7m52s   v1.22.8
    ip-10-0-70-169.us-west-2.compute.internal    Ready    <none>                 8m14s   v1.22.8
    ip-10-0-77-176.us-west-2.compute.internal    Ready    <none>                 8m11s   v1.22.8
    ip-10-0-96-61.us-west-2.compute.internal     Ready    <none>                 8m12s   v1.22.8
    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
    CODE

    NAMESPACE                NAME                                                                 READY   STATUS     RESTARTS        AGE
