Docker - Traefik Configuration
Intro
Install Docker
Ensure you have a working Docker installation on your server. If not, follow my guide on Docker - Install and Configure.
Set up Traefik
Create a new file named docker-compose.yml for Traefik. Refer to the official Traefik documentation for additional configuration options.
Example Docker-Compose File:

version: "3"
services:
traefik:
image: "traefik:v2.5"
command:
- "--api.insecure=true"
- "--providers.docker=true"
ports:
- "80:80"
- "443:443"
- "8080:8080"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock"
Start Traefik
1
docker-compose up -d
Access Traefik Dashboard
You can now access the Traefik dashboard by navigating to http://your-server-ip:8080 in your browser. Note that the --api.insecure=true flag is used for simplicity; in a production environment, consider securing the API.
Configuration
Now, let’s set up a sample service using Traefik. Create a new file named whoami.yml:

version: "3.3"
services:
whoami:
image: "containous/whoami"
labels:
- "traefik.http.routers.whoami.rule=Host(`whoami.yourdomain.com`)"
Replace yourdomain.com with your actual domain.
Deploy the Whoami Service
1
docker-compose -f whoami.yml up -d
Visit http://whoami.yourdomain.com to see the Traefik-managed service.
Conclusion
Congratulations! You’ve successfully set up Traefik as a reverse proxy using Docker. Explore the Traefik documentation for advanced configuration options and security measures.
