Traefik: The Cloud-Native Edge Router

Reverse proxies used to be hard. Traefik makes them magical. It discovers your services automatically.

Why Traefik?
#

Traditional proxies (Nginx/HAProxy) require a static config file. Every time you add a service, you edit the file and reload.

Traefik watches your Docker Engine. When you start a container with specific labels, Traefik starts routing traffic to it instantly.

Simple Configuration
#

In your docker-compose.yml:

services:
  my-app:
    image: my-app:latest
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.myapp.rule=Host(`myapp.localhost`)"

That’s it. Traefik sees the label and creates the route.

Automatic HTTPS (Let’s Encrypt)
#

Traefik can automatically request and renew SSL certificates for your domains.

command:
  - "--certificatesresolvers.myresolver.acme.email=your-email@example.com"
  - "--certificatesresolvers.myresolver.acme.storage=/acme.json"
Security: Traefik handles the complexities of TLS termination, so your application containers don’t have to worry about certificates.
