Lint and Template Gates in CI

Failing the build on invalid charts early.

Catch Bugs Before the Cluster

A broken chart should fail your pipeline, not your production cluster. CI gates let you reject bad charts the moment a pull request opens. 🛡️

helm lint Is Your First Gate

The command helm lint runs static checks on a chart: it verifies the structure, required fields, and common best-practice issues without touching any cluster.

helm lint ./mychart
