Kopf is a Python framework and library for building Kubernetes operators with minimal boilerplate, using decorator-based handlers for custom and built-in resources. It maps Kubernetes concepts to Pythonic constructs, handling API communication, status updates, and event logging automatically.

Use cases

• write a kubernetes operator in python
• automate management of custom kubernetes resources
• react to pod or namespace events with custom logic
• build a kubernetes admission webhook
• sync external systems with kubernetes resource state
• implement domain logic on top of k8s custom resources

When to choose

• you want to build Kubernetes operators quickly in Python with minimal boilerplate
• you need both sync and async handlers for resource events
• you want a stable, production-ready operator framework with semantic v1 guarantees

When to avoid

• you need a framework with active development of major new features
• your team standardizes on Go for Kubernetes controllers
• you require cutting-edge operator capabilities beyond what Kopf expresses
