EKS Explore your 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

Follow these steps:

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:

   CODE

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

2. List the Nodes using this command:

   CODE

   kubectl --kubeconfig=${CLUSTER_NAME}.conf get nodes

   Output will be similar to:

   CODE

   NAME                                         STATUS   ROLES    AGE   VERSION
   ip-10-0-122-211.us-west-2.compute.internal   Ready    <none>   35m   v1.23.9-eks-ba74326
   ip-10-0-127-74.us-west-2.compute.internal    Ready    <none>   35m   v1.23.9-eks-ba74326
   ip-10-0-71-155.us-west-2.compute.internal    Ready    <none>   35m   v1.23.9-eks-ba74326
   ip-10-0-93-47.us-west-2.compute.internal     Ready    <none>   35m   v1.23.9-eks-ba74326

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:

   CODE

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

   Output will be similar to:

   CODE

   NAMESPACE                NAME                                            READY   STATUS     RESTARTS      AGE
