Lesson 0122 min

Kubernetes architecture without the buzzwords

What actually happens when you `kubectl apply -f deployment.yaml` — from API server to scheduler to kubelet to container runtime. The mental model that lets you debug at 2am.

What this lesson teaches

· Control plane components — API server, etcd, scheduler, controller-manager
· Data plane — kubelet, kube-proxy, container runtime (containerd vs Docker)
· Reconciliation loops: the one pattern that explains all of Kubernetes
· Why etcd is fragile and how to operate it safely
· kubectl behind the scenes — understand the requests it actually makes

Lesson 0226 min

Pods, Deployments and Services — the holy trinity

We deploy a real app to a real cluster and trace every object the system creates. By the end you understand exactly what a Service does (it's not a load balancer in the way you think).

What this lesson teaches

· Pod lifecycle: pending → running → succeeded/failed states explained
· ReplicaSet vs Deployment — why both exist and when to use each
· Service types: ClusterIP, NodePort, LoadBalancer, Headless — and what each costs on AWS/Azure/GCP
· Liveness vs readiness vs startup probes — the difference that breaks production
· Common debugging patterns: kubectl describe, events, logs, exec

● Paired lab

Deploy a 3-tier app (frontend + API + Postgres) to a managed Kubernetes cluster you provision.
