This tutorial explains what a Kubernetes Operator is, walks through setting up the development environment, creating a simple Foo operator with Kubebuilder, defining CRDs and controllers in Go, testing the operator on a local Kind cluster, and suggests further enhancements.
This article explains how to define and execute performance testing workflows for Kubernetes using declarative YAML files, covering the design of custom CRDs, task orchestration, example manifests, and the implementation of core operations and monitoring.
This article traces the rapid rise of Kubernetes Operators from a niche PoC to a de‑facto standard for deploying and managing distributed stateful applications, explains how they extend the controller pattern to provide declarative, dynamic lifecycle management, compares them with StatefulSets, and details the technical evolution from TPR to CRD with concrete code examples.
