Kubewarden VS kubeval

If you're already playing with webassembly, take a look at kubewarden.io

I'm one of the developers of kubewarden, a CNCF sandbox project that operates in the same space as OPA/Gatekeeper and Kyverno.

An alternative to OPA (and Rego) is Kubewarden (kubewarden.io), which can actually run Rego policies, but really allows policy writing in any language that compiles to wasm. This opens up your options a lot.

Kubewarden is a policy engine for Kubernetes. It helps with keeping your Kubernetes clusters secure and compliant. Kubewarden policies can be written using regular programming languages or Domain Specific Languages (DSL). Policies are compiled into WebAssembly modules that are then distributed using traditional container registries.

I don't use it myself, but it seems what are you looking for. https://github.com/instrumenta/kubeval

1. Validate Using ValidKube, you can Validate your YAML files. It can help you fix the indentation also add, remove and rearrange things according to the actual YAML and Kubernetes schema. It is available as a open source repository as Kubeval . https://github.com/instrumenta/kubeval

The idea behind Validkube is to fuse together the capabilities of three other popular open-source projects (kubeval, kubectl-neat & trivy) and present them in a single view, providing users with a way to ensure YAML code hygiene and security, in one place, with just a few clicks of the button.

Kubeval - Well known, It only validates against the given Kubernetes Version but doesn’t provide a migration path

Kubeval and kubeconform are command-line tools that were developed with the intent to validate Kubernetes manifests without the requirement of having a running Kubernetes environment. Because kubeconform is based on kubeval, they operate similarly — verification is performed against pre-generated JSON schemas that are created from the OpenAPI specifications (swagger.json) for each particular Kubernetes version. All that remains to run the schema validation tests is to point the tool executable to a single manifest, directory or pattern.
