initial-traefik

Initialize and configure Traefik reverse proxy with Docker. Install Traefik, configure Docker Compose, set up service routing via path prefix or host-based routing, enable features like dashboard metrics logging tracing, configure Dashboard access via nip.io or path prefix

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"

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

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
