Maintained Helm chart serving a Cloudflare-style diagnostic page while preserving upstream HTTP status codes. The chart owns its ConfigMap, Nginx Deployment and Service, Traefik Errors middleware, and optional ForwardAuth chain.

The brunner.ninja branding and Authentik integration are cluster-specific and live in the separate homelab-gitops application. No credentials, PVCs, certificates, or public Ingress are required by this chart. The global Traefik error-page plugin is configured separately by the Traefik installation.

Install elsewhere

helm repo add brunner.ninja https://brunner.ninja/charts
helm repo update brunner.ninja
helm upgrade --install traefik-error-pages brunner.ninja/traefik-error-pages \
  --namespace default --wait --timeout 5m

Main-branch CI validates the chart, publishes a Git-describe-derived chart version to the public Helm repository, and promotes that exact version in homelab-gitops. It has no Kubernetes credential. The workflow uses PACKAGE_USERNAME, PACKAGE_TOKEN, and GITOPS_TOKEN repository secrets.

Run ./test.sh for local lint/render tests. The image version is the chart's appVersion; the chart's own Git tag versions the Helm package.
