Common Expression Language (CEL) is getting increasingly popular in the Kubernetes community. This project leverages it to validate your Helm values.

Helm CEL is a plugin that allows you to write validation rules for Helm charts in CEL (via values.cel.yaml) instead of JSON schema (values.schema.json). Its features include:

- Automatic generation of rules based on your Helm values file;
- An ability to organise your validation rules into multiple files;
- Two severity levels (errors and warnings) and reusable expressions for rules.
