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:

Add Rules to the Cluster’s Audit Policy

The cluster has an audit policy configured. The audit policy file is located at /etc/kubernetes/audit-policy.yaml. Add the following rules to the audit policy:

  1. Log the request and response body for changes to configmaps.
  2. Log the request body for changes to services and pods in the web namespace.
  3. Log metadata for changes to secrets.
  4. Create a catch-all rule to log metadata for all remaining requests.
Configure Audit Logging
  1. Configure audit logging for the cluster.
  2. Direct audit log output to a file located at /var/log/kubernetes/audit.log.
  3. Maintain old log files for a maximum of 10 days.
  4. Keep a maximum of 1 old log files.

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 use-context acgk8s.

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