# Initial Traefik Initialize and configure Traefik v3 reverse proxy with Docker Compose for service routing and load balancing. ## Quick Start ### 1. Create Configuration ```bash mkdir -p ~/.docker/compose cd ~/.docker/compose ``` ### 2. Create docker-compose.yml Use `assets/docker-compose.yml` as template. Key configuration: ```yaml services: traefik: image: traefik:v3.0 container_name: traefik ports: - "80:80" - "443:443" volumes: - /var/run/docker.sock:/var/run/docker.sock:ro - ./traefik-dynamic.yml:/etc/traefik/dynamic.yml:ro command: - --api=true - --api.dashboard=true - --providers.docker=true - --providers.docker.exposedbydefault=false - --providers.file.directory=/etc/traefik - --providers.file.watch=true - --entrypoints.web.address=:80 - --accesslog=true - --metrics.prometheus=true ``` ### 3. Create Dynamic Configuration Use `assets/traefik-dynamic.yml` as template for service routing. ### 4. Start Traefik ```bash docker compose up -d ``` ### 5. Connect Services to Network ```bash for container in <service-names>; do docker network connect compose_default $container done ``` ## Routing Options ### Option A: Path Prefix Routing (IP + Path) Access services via `http://<IP>/<service>`: ```yaml http: routers: n8n: rule: "PathPrefix(`/n8n`)" service: n8n entryPoints: - web middlewares: - n8n-stripprefix middlewares: n8n-stripprefix: stripPrefix: prefixes: - /n8n services: n8n: loadBalancer: servers: - url: "http://n8n:5678" ``` Access: `http://192.168.9.192/n8n` ### Option B: Host-Based Routing (.nip.io) Access services via `http://<service>.<IP>.nip.io`: ```yaml http: routers: n8n: rule: "Host(`n8n.192.168.9.192.nip.io`)" service: n8n entryPoints: - web services: n8n: loadBalancer: servers: - url: "http://n8n:5678" ``` Access: `http://n8n.192.168.9.192.nip.io` ### Option C: Docker Labels Configure routing directly in docker-compose.yml labels: ```yaml services: traefik: labels: - "traefik.enable=true" - "traefik.http.routers.dashboard.rule=Host(`traefik.192.168.9.192.nip.io`)" - "traefik.http.routers.dashboard.service=api@internal" - "traefik.http.routers.dashboard.entrypoints=web" ``` ## Enable Features See `references/features.md` for complete feature list and configuration. ## Common Tasks ### Add New Service 1. Connect container to network: ```bash docker network connect compose_default <container-name> ``` 2. Add router to `traefik-dynamic.yml`: ```yaml routers: myservice: rule: "PathPrefix(`/myservice`)" service: myservice entryPoints: - web middlewares: - myservice-stripprefix services: myservice: loadBalancer: servers: - url: "http://<container-name>:<port>" ``` Traefik auto-reloads configuration. ### Check Status ```bash docker logs traefik | grep -E "router|error" docker exec traefik wget -q -O - http://localhost:8080/api/http/routers ``` ### Restart Traefik ```bash docker restart traefik ``` ## References - **Features**: See `references/features.md` for all available features - **Examples**: See `references/examples.md` for common configurations - **Templates**: See `assets/` for configuration templates ## Troubleshooting - **404 errors**: Check container is connected to `compose_default` network - **Configuration not loading**: Check `traefik-dynamic.yml` YAML syntax - **Service not accessible**: Verify container name and port in service configuration - **Dashboard not working**: Ensure `--api.dashboard=true` is in command
