01 Learning Tracks

03 Cluster Anatomy
A cluster is a control plane (the brain) plus worker nodes (the muscle). See the big picture, or open up the components inside.
04 Request Flow
How does traffic actually reach your app? Follow a request from the outside world through DNS → Ingress → Service → Pod.
05 Deploy & Reconcile
What really happens when you kubectl apply? Watch your desired state travel through the control plane and become running pods — and stay that way.
