Use kubectl to connect to an ACK cluster - User Guide for Kubernetes Clusters| Alibaba Cloud Documentation Center

This topic describes how to use kubectl to connect to a cluster of Container Service for Kubernetes (ACK).

Background information

You can use the Kubernetes command-line tool kubectl to connect to an ACK cluster from your on-premises machine.

Install and set up the kubectl client.
For more information, see Install and set up kubectl.
Configure the cluster credentials.
1. Log on to the ACK console.
2. In the left-side navigation pane, click Clusters.
3. On the Clusters page, click the name of the cluster to which you want connect or click Applications in the Actions column.
4. In the left-side navigation pane, click Cluster Information.
5. On the Cluster Information page, click the Connection Information tab.
  - To connect to the cluster over the Internet, click the Public Access tab and copy the content in the code block to the file in the$HOME/.kube/config directory of your on-premises machine. By default, the kubectl retrieves cluster credentials from this directory.
  - To connect to the cluster over an internal network, click the Internal Access tab and copy the content in the code block to the file in the $HOME/.kube/config directory of your on-premises machine. By default, the kubectl retrieves cluster credentials from this directory.

If you want to connect to a cluster of ACK Managed Edition, you can run kubectl commands to connect to the cluster from your on-premises machine after you configure the kubeconfig file.
If you want to connect to a cluster of ACK Proprietary Edition, you can obtain the IP address for SSH connection to a master node from the Basic Information tab and run kubectl commands to connect to the cluster from your on-premises machine.

Note To use SSH to log on to a cluster of ACK Proprietary Edition, you must enable SSH logon when you create the cluster. For more information, see Create a cluster of ACK Proprietary Edition.
