About this Hands-on Lab

This lab provides practice scenarios to help prepare you for the Certified Kubernetes Security Specialist (CKS) exam. You will be presented with tasks to complete, as well as server(s) and/or an existing Kubernetes cluster to complete them in. You will need to use your knowledge of Kubernetes to successfully complete the provided tasks, much like you would on the real CKS exam. Good luck!

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

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].

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.

Additional Resources

Use the provided environment to complete the tasks detailed in the learning objectives.

You can access all components of the cluster from the CLI server. The control plane server is k8s-control, and the worker is k8s-worker1. If you need to log in to the control plane server, for example, just use ssh k8s-control from the CLI server.

You can also use kubectl from the CLI server, control plane node, or worker to interact with the cluster. In order to use kubectl from the CLI server, you will need to select the acgk8s cluster to interact with, like so: kubectl config set-context acgk8s.

kubectl is aliased to k, and kubernetes autocompletion is enabled. You can use the k alias like so: k get pods.
