Traefik Has a Free Cloud-Native Reverse Proxy — Auto-Discovery for Docker and Kubernetes

Traefik Auto-Discovers Services in Docker and Kubernetes

Nginx needs manual config updates every time you add a service. Traefik watches your Docker containers and Kubernetes pods — routes traffic automatically.

What Makes Traefik Special

• Auto-discovery — detects new containers/pods automatically
• Lets Encrypt — automatic TLS certificates
• Middleware — rate limiting, auth, headers, compression
• Load balancing — round-robin, weighted, sticky sessions
• Dashboard — real-time traffic visibility
• Multi-provider — Docker, K8s, Consul, file

Docker Compose Example

services:
  traefik:
    image: traefik:v3.0
    command:
      - --providers.docker=true
      - --entrypoints.web.address=:80
    ports:
      - "80:80"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

  app:
    image: myapp:latest
    labels:
      - traefik.http.routers.app.rule=Host(`app.example.com`)

Add a new service with labels — Traefik picks it up instantly.
