Description

Adds a standalone nbs-ingress Helm chart that decouples all NBS7 ingress routing from the application charts. Supports both NGINX and Traefik ingress providers via feature flags (nginx.enabled / traefik.enabled), allowing STLTs to migrate to Traefik independently of their NBS7 application version. Also includes Traefik controller Helm values for AWS (EKS) and Azure (AKS) deployments.

Adds a separate nbs6-ingress Helm chart for CDC and Montana environments that run NBS6 (Classic/WildFly) in a container. This decouples the NBS6 ingress routing from the nbs6 application chart, supporting both NGINX and Traefik providers with the same flag pattern.

Creating a new Helm chart?

Yes — charts/nbs-ingress/ is a full Helm chart containing templates for all NBS7 ingress resources (main app routes, cached static assets, data ingestion, middlewares, and optional NiFi). charts/nbs6-ingress/ is a full Helm chart for NBS6 Classic ingress routing (main routes, cached static assets, and middlewares). charts/traefik/ contains only Helm values files used with the upstream traefik/traefik chart.

Notes

• Replaces the embedded Traefik templates previously added to modernization-api and dataingestion-service — those templates have been removed and the traefikIngress.enabled values reset to false
• Existing NGINX configuration in charts/nginx-ingress/ and existing Helm templates in application charts are unchanged
• Image tag is managed by the chart's appVersion — not pinned in values files
