Versions:
kubeconform 0.7.0 is an open-source Kubernetes manifest validator created by Yann Hamon that parses YAML and JSON files against upstream JSON-Schema definitions to detect syntax errors, missing required fields, deprecated API versions and schema violations before resources reach the cluster. Designed for speed, the utility can lint entire directories of manifests in milliseconds, making it suitable for both local pre-commit checks and high-throughput CI pipelines; it exits with a non-zero code when discrepancies are found, allowing build systems to fail fast and provide immediate feedback to operators. The tool ships with schemas for all stable and beta Kubernetes objects up to the latest release, yet its real utility lies in extensibility: users can point kubeconform to custom or vendor-specific CRD schemas stored in remote Git repositories, local folders, or OCI registries, enabling validation of bespoke Custom Resource Definitions from Prometheus, Istio, Argo CD or in-house operators without additional plugins. A configurable ignore list, strict mode, and output formats ranging from plain text to JUnit XML integrate easily with GitHub Actions, GitLab CI, Jenkins, Tekton, Azure DevOps or any shell script, while a small single-binary distribution simplifies installation on developer laptops, shared jump hosts, or within containerized build stages. Since its first commit four versions ago, the project has added parallel processing, better memory pooling, and continual schema updates, keeping the validator aligned with monthly Kubernetes releases. kubeconform is available for free on get.nero.com, where downloads are supplied through trusted Windows package sources such as winget, always delivering the newest build and supporting batch installation of multiple applications.
