Connect to an ACK cluster by using kubectl

To connect to a Container Service for Kubernetes (ACK) cluster from your on-premises machine, we recommend that you use the kubectl command-line tool. This topic describes how to use kubectl to connect to an ACK cluster.

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.
   2. In the left-side navigation pane of the ACK console, click Clusters.
   3. On the Clusters page, find the cluster that you want to manage and click the name of the cluster or click Details in the Actions column. The details page of the cluster appears.
   4. 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.

      

   5. 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.
   6. 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   3d6h
      kube-node-lease   Active   3d6h
      kube-public       Active   3d6h
      kube-system       Active   3d6h
