# Traefik Deployment Repository

Traefik is excellent as a reverse proxy within Docker environments, boasting
features like automatic service discovery and automated HTTPS via Let's
Encrypt. While similar, the docker-compose files available here cater to
different use cases for deploying Traefik.

## Add services to Traefik

1. Define the external traefik network on the top-level networks key

```
networks:
  traefik:
    external: true
```

2. Attach your web container to Traefik's network via the service-level `networks` key

```
    networks:
      - traefik
```

3. Define routing for Traefik in labels, replacing "examplerouter" with something unique

```
    labels:
      traefik.http.routers.examplerouter.rule: Host(`www.example.org`)
      traefik.http.routers.examplerouter.entrypoints: websecure
      traefik.http.routers.examplerouter.tls: true
      traefik.http.services.examplerouter.loadbalancer.server.port: 80
      traefik.docker.network: traefik
```
