Purpose: Kubeconform validates Kubernetes manifests so users can catch broken configuration before deploying.
Performance: It validates and downloads manifests concurrently and caches downloaded files in memory.
Schemas: It uses a self-updating fork of the Kubernetes JSON schema registry by default to provide schemas for recent Kubernetes versions.
Custom resources: Users can configure remote or local schema locations to validate custom resources and support offline validation.
Output formats: The command line supports JSON, JUnit, TAP, and text output formats.
CI integrations: The documentation shows using Kubeconform with GitHub Actions and GitLab CI through its Docker images.
Docker registry: Kubeconform publishes Docker images to GitHub Container Registry for use in CI workflows.
Installation: The official installation guide documents Linux, macOS via Homebrew, and Windows downloads.
Validation limit: Kubeconform checks manifests against Kubernetes OpenAPI specifications, so additional server-side validations are outside its coverage.
Library status: The Go module interface is described as work in progress and not yet stable.
License: The GitHub repository identifies the project license as Apache-2.0.
Pricing caveat: The GitHub Action documentation says GitHub Container Registry bandwidth was free during its beta and might incur costs afterward.
