  1. Challenge

    Set a Restart Policy to Restart the Container When It Is Down

    Find the beebox-shipping-data pod located in the default namespace. Modify this pod so its restartPolicy will restart the container whenever it fails.

    Note: You may need to delete and re-create the pod in order to make this change.

  2. Challenge

    Create a Liveness Probe to Detect When the Application Has Crashed

    Add a liveness probe to the container that checks the container status by making an HTTP request to the container every 5 seconds. The request should check the / (root) path on port 8080.

    Note: You may need to delete and re-create the pod in order to make this change.
