The task
Task
Create a Deployment named expose in the existing prepium namespace running 6 replicas of a Pod. Specify a single container using the ifccncf/nginx:1.13.7 image.
Add an environment variable named NGINX_PORT with the value 8001 to the container, then expose port 8001.
> Note: the ifccncf/nginx:1.13.7 image does not pull in this environment (just like the real CKAD exam), so the Pods will show ImagePullBackOff. That is expected. Grading checks your Deployment and Service definition, not whether the Pods are Running.
What this tests
Roll out and update deployments, run canary and blue-green strategies, and right-size workloads. On the CKAD exam, Application Deployment 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.
