Nginx Setup with SSL for Docker Containers on Ubuntu

This repository provides a collection of scripts to automate the setup of Nginx with SSL certificates for Docker containers running on Ubuntu. The tools help you install dependencies, configure Nginx, and set up SSL certificates using Let's Encrypt.

Prerequisites

Ubuntu operating system
SSH access to your server
A domain name pointed to your server's IP address
Root or sudo privileges

Installation

Clone the repository:

git clone https://github.com/code4mk/nginx-setup-with-ssl-on-ubuntu-for-docker-container
cd nginx-setup-with-ssl-on-ubuntu-for-docker-container

Make the scripts executable:

chmod +x run.sh
chmod +x script/*.sh

Usage

Run the setup script:

./run.sh

The script provides four options:

Docker Install on Ubuntu
- Installs Docker and Docker Compose on your Ubuntu system
Nginx Install on Ubuntu
- Installs and configures Nginx
- Sets up firewall rules for HTTP/HTTPS traffic
- Enables Nginx to start on boot
Add SSL Certificate
- Installs Certbot and its Nginx plugin
- Obtains SSL certificates from Let's Encrypt
- Configures automatic renewal
- Verifies DNS configuration
Set SSL Nginx Config
- Creates Nginx configuration for your domain
- Sets up SSL certificate paths
- Configures proxy settings for your Docker container
- Creates necessary symbolic links
- Validates and reloads Nginx configuration

Configuration

When running the SSL setup scripts, you'll need to provide:

Your domain name
The port number where your Docker container is running
Confirmation for various setup steps

The Nginx configuration will:

Redirect all HTTP traffic to HTTPS
Set up SSL certificate paths
Configure proxy settings to your Docker container
Set appropriate headers for proxy communication

SSL Certificate Renewal

SSL certificates from Let's Encrypt are valid for 90 days. The setup includes automatic renewal configuration, but you can manually test the renewal process:

sudo certbot renew --dry-run

Directory Structure

script/ - Contains individual setup scripts
nginx-config/ - Contains Nginx configuration templates
temp/ - Temporary files created during setup
run.sh - Main script to orchestrate the setup process

Troubleshooting

If SSL certificate acquisition fails:
- Verify your domain's DNS settings
- Ensure your domain points to the correct IP address
- Check that ports 80 and 443 are accessible
If Nginx configuration fails:
- Check the Nginx error logs: sudo tail -f /var/log/nginx/error.log
- Verify the configuration: sudo nginx -t
