Container Service for Kubernetes:How to connect to the master node of an ACK dedicated cluster by using SSH

Step 1: Add a listener that listens on SSH port 22 to the SLB instance of the API server

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

2. On the Clusters page, find the cluster that you want to manage and click its name. In the left-side pane, click Cluster Information.

3. Click the Basic Information tab, find API Server SLB, and click the instance ID.

4. Click Create Listener in the upper-right corner and then perform the following steps.

   The following section describes how to add a listener that listens on SSH port 22 in a few steps. For more information, see Add a TCP listener.

   1. Select TCP as the listener protocol, set Listener Port to 22, and then click Next.

   2. Select Default Server Group. In the Selected Servers section, enter 22 in the Port column for all master nodes, set the weights of the master nodes based on your business requirements, and then click Next.

   3. In the Health Check step, click Next.

   4. In the Confirm step, click Submit.

   The newly created listener named tcp_22 is displayed on the Listener tab.

5. Click the Instance Details tab. The Endpoint parameter of the Billing Information section displays the public IP address of the SLB instance.

   You can use this IP address to log on to the master nodes of the ACK dedicated cluster.

Step 2: Use SSH to log on to the master nodes

When you create a cluster, you can select key pair logon or password logon. For more information, see Create an ACK dedicated cluster (discontinued). Select a logon mode based on your business requirements:

• Password logon: The default username is root. The password is the same as the password that you specified when you create the cluster.

• Key pair logon: For more information, see Connect to a Linux instance by using an SSH key pair.
