## What it is
A Java client library providing access to the full Kubernetes and OpenShift REST APIs via a fluent DSL. It includes extensions for Knative, Tekton, and other ecosystems, plus a mock server for testing Kubernetes interactions.

## Use cases
- manage kubernetes resources from java
- write java code to deploy pods and services on kubernetes
- interact with openshift api from a jvm application
- unit test kubernetes controllers with a mock server
- build a kubernetes operator in java
- watch and list kubernetes resources programmatically

## When to choose
- you need a pure-Java alternative to the official Kubernetes Java client with a fluent DSL
- you want built-in mocking for testing Kubernetes logic without a cluster
- you work with OpenShift or extensions like Knative and Tekton from the JVM

## When to avoid
- you are not on the JVM and need a client in another language
- you only need simple kubectl-style scripting where the CLI suffices
