About:
Kubeconform is a lightning-fast Kubernetes manifest validator designed to validate resources against OpenAPI schemas. Unlike older tools, it supports CustomResourceDefinitions (CRDs) and can be configured to fetch schemas from your cluster, ensuring your YAML files adhere to the specific versions and definitions of your environment before deployment.

Key Features:

High performance and parallel processing for large repositories
Support for CustomResourceDefinitions (CRDs)
Strict validation against OpenAPI schemas
Configurable remote schema fetching

Use Cases:

Validating Kubernetes manifests in CI/CD pipelines
Pre-deployment checks to prevent cluster errors
Ensuring version compatibility for CRDs

Alternatives:

kubeval – Kubeconform is significantly faster and actively maintained, with better support for newer Kubernetes versions and CRDs.
kubectl --dry-run – Kubeconform is standalone and does not require cluster access, making it ideal for static analysis in CI environments.
