Let's dive into Kubernetes operator creation
summary
Builds a working Kubernetes operator in JavaScript/TypeScript using the Kubernetes Operator Node SDK plus the Kubernetes client libraries, implements a reconcile loop that watches pods and a CRD, and wires a CustomResourceDefinition to store an external endpoint and API key. It manages 10 random-gopher pods, queries each pod via the API proxy for its gopher identity, and POSTS/PUTS that data to an external Gopher REST API. Live demo mostly succeeds: operator discovers pods, constructs gopher objects, and updates the external API on create/modify/delete.
