The task
Context
You must complete securing access to a web server using SSL files stored in a TLS Secret.
Task
Create a TLS Secret named clever-cactus in the clever-cactus namespace for an existing Deployment named clever-cactus.
Use the following SSL files:
- Certificate:
/home/candidate/clever-cactus/web.k8s.local.crt - Key:
/home/candidate/clever-cactus/web.k8s.local.key
The Deployment is already configured to use the Secret as a volume.
What this tests
Restrict RBAC and service accounts, tighten API server flags, and keep the cluster patched. On the CKS exam, Cluster Hardening tasks are graded purely on what you build in the cluster - not multiple choice - so the only way to get faster is to do them on a real cluster against a clock.
Practice it for real
The public description lets you study the task before signing up. Full access includes this live lab; the selected Task of the Week is free with an account. You solve the task in a real terminal, hit validate, and a programmatic checker scores exactly what you got right and wrong (with partial credit). You can open the solution while practising, then retry and use the failed checks to improve your score.
