CDK8s Applications

Define Kubernetes applications using Python instead of YAML. cdk8s (Cloud Development Kit for Kubernetes) is a CNCF Sandbox project that provides type-safe, programmable infrastructure for Kubernetes.

Overview

What is cdk8s?

• Define K8s resources using Python, TypeScript, JavaScript, Java, or Go
• Synthesizes to standard Kubernetes YAML manifests
• Works with any Kubernetes cluster (cloud-agnostic)
• Built on the same concepts as AWS CDK
• CNCF Sandbox project (GA since October 2021)

Key Benefits:

• Type Safety: Catch configuration errors at development time
• IDE Support: Autocomplete, inline docs, refactoring
• Reusability: Create custom constructs for common patterns
• Testability: Unit test infrastructure code
• Reduced Boilerplate: Intent-driven APIs vs verbose YAML
