Short, interactive exercises for infrastructure and cloud security fundamentals.

Admission Policy Bouncer

You are the admission controller. Pods arrive at the door with their security specs — swipe right to admit, swipe left to deny, based on the active policy. Eight levels covering privileged containers, host namespaces, non-root enforcement, capabilities, image registries, resource limits, privilege escalation, and the full PSA restricted profile.

▌ You'll learn

Identify privileged containers and understand why they are dangerous
Recognize host namespace misuse (hostPID, hostIPC, hostNetwork)
Apply non-root user enforcement via runAsNonRoot and runAsUser

Kubernetes Scheduler

You are the kube-scheduler. Drag pods onto the right worker nodes based on resources, selectors, taints, and affinities. Endless rounds with scaling difficulty.

▌ You'll learn

Understand how kube-scheduler fits pods by CPU and memory requests
Use nodeSelector to pin pods to labeled nodes
Apply taints and tolerations to control scheduling
