Setting up Nginx with Certbot using Docker Compose

Setting up Nginx with Certbot (Let's Encrypt) can be a complex task, especially if you want to use Docker. Many guides on the internet require multiple steps and a good understanding of how the components should work together. This setup is designed to simplify the configuration of Nginx with Certbot using Docker Compose, working right out of the box.

How It Works

• Copy and Run: Simply copy the provided setup to your server and run docker compose up.
• First Run Setup:
  • Certificates will be requested from Let's Encrypt.
  • The certificates will be passed into the Nginx container.
  • Nginx will start without any hassle.
• Automatic Renewal: A separate container with Certbot will automatically renew SSL certificates and restart Nginx as needed.

Features

• Minimalist Build: The setup consists of just a few files.
• Security Focused: Maximizes the use of internal mechanisms of Certbot and Nginx for improved security in the configuration (no hard-to-understand shell scripts that need verification).

Steps to Get Started

• Clone this repository to your server:

git clone https://github.com/seliverstov-maxim/docker-nginx-certbot.git
cd docker-nginx-certbot
cp .env.example .env

• Update DOMAIN and EMAIL in .env file:

DOMAIN='example.com'
EMAIL='test@example.com'

• Start the Docker containers:
  • Load domain and email from .env variables.
  • Run Docker Compose.

docker compose up -d

That's it! Your Nginx server with automatic SSL certificate management should now be up and running.
