Configuring Traefik

Now that we've grasped the basics of Traefik, let's dive into its configuration. Traefik's simplicity shines in its configuration file, often written in YAML. 

Below is a basic configuration file:

# traefik.yml
    address: :80
    address: :443
    endpoint: "unix:///var/run/docker.sock"
    exposedByDefault: false
  dashboard: true
  • `entryPoints` define where incoming traffic will be accepted (HTTP, HTTPS in this example).

  • `providers` specify how Traefik should discover services. Here, we're using Docker as the provider.

  • `api` enables the web dashboard.

To run Traefik with this configuration:

 docker run -d -p 80:80 -p 443:443 -v /path/to/traefik.yml:/etc/traefik/traefik.yml traefik:v2.5

This simple setup lets Traefik start routing traffic based on Docker container labels.

Below are some more custom ways to configure Traefik.

2. Routers and Services

  • Define routers that specify how incoming requests should be routed.

  • Define services that define where traffic should be directed.

  • Attach routers to services.

Let's look at a sample router and service configuration.

         rule: "Host(``)"
         service: my-service
             - url: "http://backend-service"

3. Middlewares

Middlewares allow you to apply additional processing to requests and responses. They can be used for authentication, rate limiting, rewriting, etc. Define middlewares and attach them to routers.

Let's look at a sample middleware configuration.

             - "user:hashed_password"
         rule: "Host(``)"
         service: my-service
           - my-middleware

4. TLS/HTTPS Configuration

If you want to enable HTTPS, configure TLS certificates, define a certificate resolver, and attach it to routers.

Let's look at a sample TLS configuration.

         email: ""
         storage: "/acme.json"
           entryPoint: "http"
         rule: "Host(``)"
         service: my-service
           certResolver: myresolver

5. Access Control

Secure access to the Traefik dashboard using basic authentication or other methods.

Here is an example of dashboard access control.

           username: "admin"
           password: "hashed_password"

6. Load Balancing

Customize load-balancing algorithms and settings as needed.

Here's a sample load balancing configuration.

           method: "drr"  # Dynamic Round Robin

7. Logging and Metrics

Configure logging to various outputs (file, console, etc.) and enable metrics for monitoring.

Here is a sample logging and metrics configuration.

     filePath: "/var/log/traefik.log"
       entryPoint: "metrics"

8. Custom Error Pages

Define custom error pages for specific HTTP status codes.

Here's an example of a custom error page configuration.

          rule: "Host(``)"
          service: my-service
            status: 404
            service: error-service

9. TCP and UDP Services

Traefik can handle TCP and UDP traffic, not just HTTP. Configure routers and services accordingly.

Let's look at a sample TCP configuration.

          rule: "HostSNI(``)"
          service: tcp-service
              - address: "backend-service:8080"

Use Cases of Traefik

Traefik excels in various use cases. Let's explore a few practical scenarios.

1. Load Balancing Microservices

Imagine you have a microservices architecture with multiple backend services. 

Traefik can distribute incoming traffic evenly among these services, ensuring optimal resource utilization and fault tolerance. 

Here's an example of Docker Compose configuration:

    version: "3"
       image: my-web-app
         - "traefik.http.routers.web.rule=Host(``)"
       image: my-api-service
         - "traefik.http.routers.api.rule=Host(``)"

In this setup, Traefik routes web traffic to the `web` service and API requests to the `api` service.

2. Automatic SSL Termination

Ensuring secure communication is crucial. Traefik can automatically obtain and renew SSL certificates from Let's Encrypt, simplifying the process of securing your services. 

Just add the following labels to your services:

  • "traefik.http.routers.web.tls=true"

  • "traefik.http.routers.web.tls.certresolver=myresolver"

Traefik handles the rest, making sure your traffic is encrypted without manual certificate management. Handy!

3. Middleware and Request Routing

Traefik supports middlewares for advanced request handling. You can implement authentication, rate limiting, and URL rewriting. 

For instance, to add basic authentication:


  • "traefik.http.routers.web.middlewares=auth"

  • "traefik.http.middlewares.auth.basicauth.users=user:hashed-password"

We have talked about Traefik, now let’s talk about another popular open-source tool “Nginx”.

Step 2: Install Nginx Proxy Manager

1. Create a directory for Nginx Proxy Manager and navigate to it:

   mkdir ~/nginx-proxy-manager
   cd ~/nginx-proxy-manager

2. Create a `docker-compose.yml` file for Nginx Proxy Manager:

   version: '3'
       image: jc21/nginx-proxy-manager:latest
         - 80:80
         - 81:81
         - 443:443
         DB_MYSQL_HOST: "db"
         DB_MYSQL_PORT: 3306
         DB_MYSQL_USER: "npm"
         DB_MYSQL_PASSWORD: "npm"
         DB_MYSQL_NAME: "npm"
         - ./data:/data
         - ./letsencrypt:/etc/letsencrypt

3. Create the `docker-compose.override.yml` file to customize your installation (if needed):

   version: '3'
         TZ: "Your_Timezone"

4. Start the Nginx Proxy Manager containers:

   docker-compose up -d

Step 3: Configure Nginx Proxy Manager

1. Access the Nginx Proxy Manager web interface by visiting `https://your_domain_or_ip:81` in your web browser.

2. Login using the default username `` and password `changeme`. It is highly recommended to change the password immediately.

3. Once logged in, you can start configuring proxy hosts, SSL certificates, and more through the web interface.

4. Add a proxy host by clicking on the "Proxy Hosts" tab and then the "Add Proxy Host" button. Fill in the necessary details, including the domain name, target IP, and port of the backend service.

5. Set up SSL certificates for your domains using the built-in Let's Encrypt integration for HTTPS.

6. Customize advanced settings as needed, such as HTTP to HTTPS redirection, security headers, and more.

Step 4: Update DNS Records

Ensure that your domain or subdomain's DNS records point to your server's IP address.

Here's a basic example of an Nginx server block configuration for serving a static website:

server {
    listen 80;
    root /var/www/html;
    index index.html;
    location / {
        try_files $uri $uri/ =404;

In this configuration:

  • `listen` defines the port (80 for HTTP) and `server_name` specifies the domain names.

  • `root` points to the directory containing the website's files.

  • `location` block handles URL routing and serves `index.html` for requests to the root URL.

After saving the configuration, you can test it and reload Nginx with these commands:

sudo nginx -t         	   
# Test the configuration

sudo systemctl reload nginx   
# Reload Nginx with the new configuration
