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.
A deployment is running without health probes or graceful shutdown configuration. Add startup, liveness, and readiness probes plus a preStop hook and terminationGracePeriodSeconds to make it ready for real traffic.
A webapp deployment in the prod namespace is stuck in CrashLoopBackOff. The application's startup probe checks that its existing config directory is intact before the container is marked healthy. Fix the deployment so configuration is injected correctly and the pod reaches Running state with its health check endpoint responding on port 8080.
Add HTTP-based liveness and readiness probes to an existing Kubernetes Deployment and verify application health and availability.
