## What it is
Kubeval is a command-line tool that validates Kubernetes YAML or JSON configuration files against schemas generated from the Kubernetes OpenAPI specification, supporting multiple Kubernetes versions. The project is no longer maintained, with kubeconform recommended as its replacement.

## Use cases
- validate kubernetes yaml manifests before applying them
- catch invalid resource definitions in ci pipeline
- check kubernetes config files against a specific k8s version schema
- lint helm template output for schema errors
- validate json kubernetes manifests

## When to choose
- you need a lightweight, fast kubernetes manifest validator in a legacy pipeline already using it
- you cannot use newer tools and only need basic schema validation

## When to avoid
- starting a new project - use kubeconform instead
- you need validation of custom resource definitions
- you need actively maintained tooling with support for newer Kubernetes versions
