Challenge

Use Trivy to Scan the Images Used in Pods

Scan all of the images used by Pods in the sunnydale namespace.

Feel free to consult the Trivy documentation.

Note: Trivy is already installed on the control plane node only.

Older versions of Trivy use a command like trivy [image name] to scan an image. This environment uses a newer version where you must specify that you want to scan an image. The command looks like trivy image [image name].
Challenge

Delete Pods That Have Container Images with Severe Vulnerabilities

Delete any Pods in the sunnydale namespace that have high or critical-level vulnerabilities. Feel free to use --force, as these Pods do not need to shift down gracefully.
