Extending Kubernetes with Operators

on YouTube ↗29m

" summary

Creates a Kubernetes operator in Go using Operator SDK that registers a myapp CRD and implements a reconcile function to create a Deployment, Service and Ingress. Installs the operator into a Minikube cluster via make install run, verifies resources with Lens, and shows the single YAML custom resource triggering all workloads. Mentions alternative installs via Helm or OLM, using operatorhub.io, and recommends unit testing with Ginkgo. Demo runs locally though live Ingress sometimes needs retries.
