Kubernetes as LEGO: Building Platforms one block at a time
summary
Shows a concrete path from primitives to a working platform: containerize a Django app, run Postgres with a StatefulSet and PVC, add Celery + Redis and WebSocket channels, use minikube locally, then manage overlays with Kustomize and package reusable charts with Helm, finally implement a custom operator in plain Python using kopf to automate scaling and backups. The live cafe demo runs and scales; manifests, commands and repo are available for hands-on reproduction.
