Kubernetes Operators: A Practical Dive Using Go and Kustomize
Kubernetes has revolutionized the way we deploy and manage containerized applications. However, as applications grow in complexity, managing their lifecycle becomes increasingly challenging. Enter Kubernetes Operators—a powerful pattern that extends Kubernetes’ capabilities to manage complex applications seamlessly. In this article, we’ll explore what Operators are, why they’re beneficial, and how to build one using Go and Kustomize, drawing insights from the kube-operator project. What Is a Kubernetes Operator? A Kubernetes Operator is a method of packaging, deploying, and managing a Kubernetes application. It extends the Kubernetes API to create, configure, and manage instances of complex applications on behalf of a Kubernetes user. Operators encode operational knowledge into software, automating tasks like deployment, scaling, and recovery. ...
