Overview

Update k8s.io/kube-openapi from digest c8a335a to 589584f.

Dependency Information

• Package: k8s.io/kube-openapi
• Type: Indirect dependency (pulled in by k8s.io/api, k8s.io/apiextensions-apiserver, k8s.io/apimachinery, and other Kubernetes packages)
• Old version: v0.0.0-20250318190949-c8a335a9a2ff
• New version: v0.0.0-20250910181357-589584f1c912
• Location: go.mod, api/go.mod, contrib/gomaxprocs-webhook/go.mod, hack/tools/go.mod

Usage in hypershift

k8s.io/kube-openapi is a core Kubernetes library that provides OpenAPI schema generation and validation capabilities. It is used throughout the project via Kubernetes client libraries.

• Primary usage: OpenAPI schema generation and validation for Kubernetes APIs
• Impact: Runtime - This library is used by core Kubernetes packages for API schema handling
• Files affected: Extensive vendor/ directory updates across multiple go.mod files

Changes in Update

This update includes several improvements and fixes:

• Add k8s-short-name and k8s-long-name formats for better Kubernetes resource naming
• Add OpenAPIModelNamer and opt-in generator support for improved code generation
• Bugfix: walk on parameter references for proper OpenAPI spec handling
• Drop usage of forked copies of goyaml.v2, migrating to go.yaml.in/yaml/v3
• Drop go 1.21 from supported versions (now requires go 1.22+)
• Bump gnostic-models dependency
• Update to latest structured-merge-diff and gengo libraries

How to Test

Since this is an indirect dependency used by Kubernetes core libraries, testing should focus on ensuring proper Kubernetes API interactions:

1. 1. Run unit tests:

         make test
         

2. Run integration tests:

   make e2e
   

3. Verify API server functionality:

• Test cluster creation and deletion
• Verify API schema validation works correctly
• Check that CRD operations function properly

4. Run linter and code generation:

   make verify
   

Expected behavior: All tests should pass, and Kubernetes API interactions should function normally without schema validation errors.
