Your first week with Kubernetes, without the overwhelm

The reason Kubernetes feels overwhelming is that most tutorials throw twenty objects at you at once. You don't need twenty. You need four, in order.

Start with the smallest unit

A Pod runs your container. That's it. Deploy one, break it, read the logs. Everything else exists to manage Pods.

Then make it reliable

A Deployment keeps N copies of your Pod alive and rolls out new versions safely. This is where "self-healing" comes from.

Then make it reachable

A Service gives your Pods a stable address. An Ingress routes outside traffic to that Service. Now you have something a browser can hit.

Then make it configurable

ConfigMaps and Secrets pull configuration out of your image. Once these four ideas click, RBAC, Helm, HPA and probes are just refinements — not new worlds.

Give yourself a week per layer, always with a running cluster in front of you. Reading about Kubernetes teaches you nothing; running it teaches you everything.
