Kusteval - K8s Kustomize + Kubeval Github Action

Allows for the evaluation of kustomize files "in-memory", so that you don't have to generate, store or continually update generated Kubernetes files in Git.

Usage

Locally

docker run {image}

TODO

Please feel welcome to open a PR for anything - with a priority on:

• I could use some help "testing" a failure and having it return successful if it fails (see my workflow)
• General review for best practice
