In this part of exercise, you create a Pod that has one container, and you project Pod-level fields into the running container as files. Here is the manifest for the Pod
In the manifest, you can see that the Pod has a downwardAPI Volume, and the container mounts the volume at /etc/podinfo.

The first element specifies that the value of the Pod's metadata.labels field should be stored in a file named labels. The second element specifies that the value of the Pod's annotations field should be stored in a file named annotations.
