Kubernetes Pod, Service & Deployment
Run a web app on a mock cluster: scale it, kill a pod and watch Kubernetes bring the desired state back.
🎯 You will learn to
- Know pod, deployment and service
- Scale replicas
- See self-healing
🧪 Live environment
Runs entirely in your browser: nothing is installed, no real cloud account is used and your code is never sent to our server.

✅ Steps & checkpoints
🗺️ Desired state loop
A Deployment asks for 3 replicas; the controller keeps 3 pods running and the Service sends traffic only to ready ones.
The 2D diagram shows the exact flow, ports and trust boundaries. The 3D scene is a concept view of the same parts; packets travel along the same arrows.
🤔 Think about it
Why does a service send traffic only to ready pods?
🛡️ Safety & cost
Pipelines run in a simulator. No repository or cluster is changed.
🧹 Cleanup
Nothing to clean up.
