Focused, hands-on problems for sharpening your DevOps and server-side skills. Some teach specific concepts while others mirror real-world scenarios. Every challenge includes hints, feedback, and automated solution checks.
Create a Pod in the processing namespace that runs a short task and exits successfully, reaching a Completed status without using a Job controller.
Add a sidecar container to an existing Deployment that tails a shared log file written by the main application container. Use a shared volume to make the log file available to both containers.
A Service exists in a namespace. Use a temporary Pod to resolve DNS, save the output, and confirm the Pod is automatically removed after the tasks complete.
Practice the fundamental lifecycle of a Kubernetes Pod: creation, inspection (IP, node), interaction (executing commands, checking logs), and deletion.
