Container Service for Kubernetes:Control public access to the API server of a cluster

Associate an EIP with the API server when you create a cluster

When you create a cluster, select Expose API Server with EIP to enable public access to the API server of the cluster. For more information about how to create a cluster, see Create an ACK managed cluster and Create an ASK cluster.

Associate an EIP with the API server after a cluster is created

1. Log on to the ACK console. In the left-side navigation pane, click Clusters.

2. On the Clusters page, click the name of the cluster that you want to manage and click Cluster Information in the left-side navigation pane.

3. On the Cluster Information page, click the Basic Information tab. In the Cluster Information section, click EIP.

   

4. In the EIP dialog box, select an EIP and click OK.

   After the EIP is associated with the API server, a public IP address appears on the right side of the API Server Public Endpoint field.

   Important

   The API server restarts after you associate an EIP with the API server. We recommend that you do not perform operations on the cluster during the restart process.

Disassociate or change an EIP

You can disassociate or change the EIP that is associated with the API server of a cluster. After you disassociate the EIP from the API server of a cluster, the API server cannot be accessed over the Internet.
