  1. Log on to the EDAS console.
  2. Go to the Application Overview page by using one of the following methods:
    • In the left-side navigation pane, choose Resource Management > Container Service Kubernetes Clusters or Resource Management > Serverless Kubernetes Clusters. In the top navigation bar, select a region. In the upper part of the page, select a microservice namespace. On the Container Service Kubernetes Clusters or Serverless Kubernetes Clusters page, click a cluster ID. In the Applications section of the Cluster Details page, click the name of the application that you want to manage.
    • In the left-side navigation pane, click Applications. In the top navigation bar, select a region. In the upper part of the page, select a microservice namespace.
