Building Platform Custom Resource Definitions
Learn to extend Kubernetes with Custom Resource Definitions (CRDs) for platform abstractions.
Lab Overview
This hands-on lab teaches you to build Custom Resource Definitions that enable platform-level abstractions in Kubernetes.
You'll learn to:
- Understand CRD structure and schema validation with OpenAPI v3
- Create platform-specific CRDs for common infrastructure patterns
- Implement validation webhooks for custom resources
- Test and iterate on CRD designs for developer experience
Custom Resource Definitions are foundational to building platform abstractions that simplify infrastructure for development teams.
What You'll Learn
Understand CRD structure and OpenAPI validation schemas
Create platform CRDs with proper versioning
Implement validation for custom resources
Test CRD behavior with kubectl and client tools
