FAQPage Schema

How do I build production-grade Helm charts with schema validation and unit testing?▼

You can build production-grade Helm charts by following a mandatory 6-step workflow that enforces updates to values.schema.json, writes unit tests, and validates templates through helm-unittest before release.

What is the best way to add schema validation to an existing Helm chart?▼

The best way to add schema validation is updating values.schema.json within a structured development workflow that enforces strict input validation before template rendering and subsequent unit testing.

Does this Helm chart workflow support unit testing with helm-unittest?▼

Yes, this workflow explicitly supports helm-unittest for creating CI-ready validation and real-world testing strategies. Unit tests are a mandatory step in the 6-step process before any chart release.

How do I secure Helm charts for production using PodSecurityContext and OCI signing?▼

To secure Helm charts for production, apply security hardening practices including PodSecurityContext configuration, OCI signing, and RBAC integration. This ensures compliance and external secret integrations across complex charts.

Can I use this workflow to migrate complex Helm charts to OCI registries and Helm 4?▼

Yes, you can use this workflow to migrate complex Helm charts to OCI registries and Helm 4. It provides specific best practices and transition patterns for migrating existing charts.

Why do I need to update values.schema.json before writing unit tests for my Helm chart?▼

You need to update values.schema.json before writing unit tests because the 6-step workflow mandates schema validation first. This ensures all template inputs are strictly defined and validated before testing rendering logic.
