Kubernetes for the Spring Developer

on YouTube ↗21m

" summary

Kubernetes fundamentals (API server, etcd, controller manager, scheduler, kubelet, kube-proxy) lead into a live demo: a Spring Boot app is built into a Docker image (OpenJDK8 base), pushed to Docker Hub, deployed on GKE as a Deployment, exposed with a LoadBalancer (nodePort 31264), backed by Postgres using a PersistentVolumeClaim, then scaled to 3 replicas. Rolling image updates replace pods and the Postgres volume detaches and reattaches so data persists — the demo completes successfully.
