This topic describes how to upgrade the configurations of a Pay-As-You-Go Master node in a dedicated Kubernetes cluster. Dedicated Kubernetes clusters are managed by users. Therefore, the Master node must be configured based on the users' needs.

Prerequisites

A Kubernetes cluster is created. For information about how to create a Kubernetes cluster, see Create a Kubernetes cluster.

Procedure

  1. Log on to the Container Service console.
  2. In the left-side navigation pane under Container Service-Kubernetes, choose Clusters > Nodes.
  3. On the Nodes page, click the instance ID of the target Master node.

    On the Instance Details page, you can view the instance information, such as the instance type.

  4. In the Configuration Information section, click Change Instance Type.
    If the instance is running, the Change Instance Type button is dimmed. In this case, you must click Stop in the upper-right corner before performing the following operations.
  5. On the displayed Instance Type page, select the target instance type, and click Confirm. For more information about the instance types, see Select ECS instances.
  6. On the displayed Change success page, click OK.
    Then, you can view the instance type on the displayed Instances page.
  7. Select the instance and click Start. Then, the Master node is automatically added to the cluster and the status of the node becomes Running.

What to do next

You can repeat the preceding steps (from step 4 to step 7) to upgrade other Master nodes. For information about how to upgrade a Master node of other billing methods, see Overview of configuration changes.
