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.)
Challenge

Mesh the Application with Linkerd
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 | 
  linkerd inject - | 
  kubectl apply -f -
```
Once the application is meshed, watch the dashboard to see additional data about the application become available.
Challenge

Explore the Changes to Application Components Made by Linkerd

Use kubectl to locate the application's Pods in the default Namespace. Use kubectl describe pod <Pod name> to view more detailed information about one of the Pods. See if you can spot information about the Linkerd sidecar container when examining the Pod!
