    Explore the Linkerd Dashboard

    Open the Linkerd dashboard in a browser.

    Access the dashboard at http://<k8s Server Public IP>:30080.

    Feel free to explore! See if you can locate any information relating to the Terrapin application's components. (Hint: The application lives in the default Namespace.)

    The application's components are located in the default Namespace. You can mesh the application with Linkerd like so:

    kubectl get -n default deploy -o yaml |

  kubectl apply -f -

    Once the application is meshed, watch the dashboard to see additional data about the application become available.
