## What it is
kube is a Rust client for Kubernetes, modeled after client-go, with an async controller runtime inspired by controller-runtime and derive macros for CRDs inspired by kubebuilder. It is a CNCF Sandbox project providing generic abstractions for reflectors, controllers, and custom resource interfaces.

## Use cases
- write a Kubernetes controller in Rust
- interact with Kubernetes resources from Rust code
- build a Kubernetes operator for a custom resource
- watch and reflect cluster state like deployments or pods
- manage CRDs with typed Rust structs
- patch or delete pods programmatically

## When to choose
- you are building Kubernetes operators or controllers in Rust
- you need a typed, async client for the Kubernetes API
- you want kubebuilder-style CRD derive macros in Rust

## When to avoid
- you need a Go-based controller with the full controller-runtime ecosystem
- you only need to run kubectl commands from a shell
- your project does not use Rust

## Facets
- artifact type: library
- maturity: stable
- function: database-driver, middleware, configuration-management, developer-tools
- domain: cloud-computing, infrastructure-as-code, developer-tools
- platform: rust, windows, cross-platform
