Docker Proxy Network

A Docker-based reverse proxy setup using nginx-proxy and Let's Encrypt for automatic SSL certificate management.

Overview

This project provides a containerized nginx reverse proxy that automatically routes traffic to Docker containers and manages SSL certificates using Let's Encrypt. It's designed to simplify the deployment of multiple web applications on a single server.

Features

• Automatic reverse proxy configuration for Docker containers
• Automatic SSL certificate generation and renewal via Let's Encrypt
• Support for custom virtual host configurations
• HTTP Basic Authentication support
• Shared network for container communication

Prerequisites

• Docker
• Docker Compose

Installation

1. Clone the repository:

git clone https://github.com/takashiraki/docker_proxy_network.git
cd docker_proxy_network

2. Start the services:

docker-compose up -d

Usage

Setting up a web application

To use this proxy with your web application, add the following to your application's docker-compose.yml:

version: "3"

services:
  your-app:
    image: your-app-image
    environment:
      - VIRTUAL_HOST=yourdomain.com
      - LETSENCRYPT_HOST=yourdomain.com
      - LETSENCRYPT_EMAIL=your-email@example.com
    networks:
      - my_proxy_network

networks:
  my_proxy_network:
    external: true

Custom Virtual Host Configuration

Place custom nginx configuration files in the ./vhost.d/ directory. The filename should match your domain name.

HTTP Basic Authentication

To add password protection to a domain, create an htpasswd entry in the ./.htpasswd file:

htpasswd -c .htpasswd yourdomain.com username

Directory Structure

• ./certs/ - SSL certificates storage
• ./vhost.d/ - Custom virtual host configurations
• ./.htpasswd - HTTP Basic Authentication credentials
• ./infra/nginx/ - Custom nginx-proxy build files

Ports

• 80 - HTTP
• 443 - HTTPS

Networks

The proxy creates a network named my_proxy_network that other containers can join to be proxied.
