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.
See how Kubernetes determines BestEffort, Burstable, and Guaranteed classes from resource configuration - and which pods get evicted first under pressure.
Create a ResourceQuota to limit resource consumption and object counts in a namespace, then deploy a compliant application with Burstable QoS.
Understand ResourceQuota limits and create a Pod with Guaranteed QoS class that uses half of the namespace's allocated resources.
Understand and implement Kubernetes Quality of Service (QoS) classes. Create Deployments and Pods with different QoS classes and identify eviction priority during resource pressure.
