GitHub Action
Monokle Validation
Monokle Action is a GitHub Action for static analysis of Kubernetes resources.
Use it to prevent misconfigurations within Kustomize, Helm or default Kubernetes resources. The output is available as a SARIF file which you can upload to GitHub CodeScan.
Under the hood it uses @monokle/validation which allows you to configure validation rules extensively.
The action will find problems for you.
You can configure the validator whether a problem is an error or a warning.
The action fails when at least one error is found. Only warnings will not result in a failure and allow you to still merge. This allows for transition periods in your policies.
