Traefik Reverse Proxy Example with Docker Compose

This example demonstrates how to use Traefik as a reverse proxy for a web service defined in a Docker Compose file. Traefik routes incoming requests based on specified rules and forwards the traffic to the web service.

Prerequisites

• Docker
• Docker Compose
• Traefik installed and configured (e.g., as a container service)

Setup Overview

• Traefik acts as a reverse proxy for the web service.
• Incoming requests are routed based on hostnames and custom headers.
• Traefik uses defined middlewares for additional request processing.

How It Works

• Traefik listens for incoming requests on specified entry points (e.g., websecure for HTTPS).
• Requests matching defined routing rules are forwarded to the web service.
• Middleware can be applied to handle authentication, whitelisting, etc.

Example Docker Compose Configuration

The following docker-compose.yml file shows the service configuration with Traefik labels.

Quick Start

1. Copy docker-compose.yml to your project directory.
2. Adjust the volumes and environment variables as needed.
3. Run docker-compose up -d to start the services.
