Focused hands-on problems designed to help you hone your DevOps or Server Side skills. Some challenges are more educational, while others are based on real-world scenarios. The platform provides hints and feedback for each challenge, including automated solution checks.

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.
