Connecting to Kubernetes Clusters with Web Client

Overview

With KAC Web Client, you can access Kubernetes clusters directly from your browser without installing a separate Agent, and explore and manage resources.

You can enter from the cluster detail screen in the Kubernetes menu using the Connect button, or if you have already selected a Role and a specific cluster, you can go directly to Web Client from the top menu on the user page.

Web Client Screen Layout

When you connect, the Cluster Overview screen appears, where you can check the overall status of the cluster.

• Left sidebar (Resource Browser): Browse resources in the cluster by category.
• Right main area: Displays the list or details of the selected resource.
• Bottom panel: Displays Pod logs and Shell terminal in tab format. It appears when you click the Logs or Shell button on the detail screen displayed after clicking a specific target in the list.
