Traefik Cookbook & Recipes

Production blueprints and ready-to-run configurations for deploying RouteWarden on Traefik Proxy.

---

1. Global EntryPoint Shield (Docker Compose)

Protect every microservice, API, and container automatically at Traefik's web or websecure entrypoints without needing to attach middleware labels to individual containers:

services:  traefik:    image: traefik:v3.0    command:      - "--api.insecure=true"      - "--providers.docker=true"      - "--entrypoints.web.address=:80"      - "--entrypoints.web.http.middlewares=traefik-warden@docker"      - "--experimental.plugins.routewarden.modulename=github.com/routewarden/traefik-warden"      - "--experimental.plugins.routewarden.version=v1.2.1"    labels:      - "traefik.enable=true"      - "traefik.http.middlewares.traefik-warden.plugin.routewarden.enabled=true"      - "traefik.http.middlewares.traefik-warden.plugin.routewarden.enableDefaultPatterns=true"      - "traefik.http.middlewares.traefik-warden.plugin.routewarden.response.mode=json"      - "traefik.http.middlewares.traefik-warden.plugin.routewarden.response.statusCode=404"      - 'traefik.http.middlewares.traefik-warden.plugin.routewarden.response.body={"error":"Not Found"}'

2. Service-Specific Defense with Allowlist Exceptions

Apply custom regex filters and safe whitelists on an individual web application:

TraefikRouteWarden CLI

services:  webapp:    image: nginx:alpine    labels:      - "traefik.enable=true"      - "traefik.http.routers.webapp.rule=Host(`app.example.com`)"      - "traefik.http.routers.webapp.middlewares=app-warden"      - "traefik.http.middlewares.app-warden.plugin.routewarden.enabled=true"      - "traefik.http.middlewares.app-warden.plugin.routewarden.pathPatterns=(?i)^/admin(/.*)?$,(?i)^/metrics$"      - "traefik.http.middlewares.app-warden.plugin.routewarden.allowPatterns=(?i)^/admin/health$"      - "traefik.http.middlewares.app-warden.plugin.routewarden.allowedIps=10.0.0.0/8,192.168.1.100"

3. Kubernetes IngressRoute (Traefik CRD)

Deploy RouteWarden in Kubernetes clusters using Traefik's Custom Resource Definitions:
