Container Service for Kubernetes:Connect to an ACK cluster by using kubectl

In addition to the Container Service for Kubernetes (ACK) console, you can also use the Kubernetes command-line tool kubectl to manage clusters and applications. This topic describes how to connect to an ACK cluster from a kubectl client.

1. Download the latest kubectl client from the Kubernetes version description page.
2. Install and set up a kubectl client.

   For more information, see Install and set up kubectl.

3. Configure the cluster credentials.

   You can view cluster credentials on the details page of a cluster.

   1. Log on to the ACK console and click Clusters in the left-side navigation pane.
   2. Click the cluster whose credentials you want to view.
   3. Optional:Click the Basic Information tab. In the Cluster Information section, you can view the public and internal IP addresses that are used to connect to the cluster.

      

   4. Click the Connection Information tab and copy the cluster credentials to a local file on your on-premises machine.
      You can create a $HOME/.kube/config file and copy the cluster credentials to this file. This is the default file from which kubectl obtains the cluster credentials. You can also create another file, for example, /tmp/kubeconfig, and copy the cluster credentials to the file. Then, run the export KUBECONFIG=/tmp/kubeconfig command.
   5. Run the following command to check whether the kubectl client is connected to the cluster:

      kubectl get namespace

      Expected output:

      NAME              STATUS   AGE
      default           Active   4h39m
      kube-node-lease   Active   4h39m
      kube-public       Active   4h39m
      kube-system       Active   4h39m
