Bootiful Kubernetes Operators

on YouTube ↗48m

" summary

Shows how to implement a custom Kubernetes operator in Java using Spring Boot and the kubernetes-java-client: author creates a CRD, shared informer, reconciler that applies a ConfigMap and an NGINX Deployment (two replicas) with ownerReferences, idempotent create/replace logic and a 10s retry on failure. Builds the controller image with Cloud Native Buildpacks, pushes to a registry, deploys the operator, and demonstrates the live “hello spring” page. Tests use k3s testcontainers for integration verification.
