Docker Deployment with Nginx HTTPS

Quick Start

For Docker web application deployment with HTTPS support:

1. Configure Nginx with SSL certificates (see nginx-https.md)
2. Set up docker-compose.yml with certificate volume mounting
3. Configure Cloudflare Tunnel to connect external domain to local container

Common Tasks

Task	Reference
Nginx HTTPS configuration	nginx-https.md
Cloudflare Origin Certificate	cf-origin-cert.md
Docker data persistence	data-persistence.md
Cloudflare Tunnel setup	cf-tunnel.md

Architecture Overview

Internet → Cloudflare Edge (HTTPS) → Cloudflare Tunnel → Ubuntu/Docker (Nginx)

Key Principles

• Always use named Docker volumes for persistent data
• Nginx should redirect HTTP (80) to HTTPS (443) in production
• Cloudflare Origin Certificates are for CF-to-origin encryption only
• Tunnel connects to HTTP or HTTPS - configure based on nginx setup

Troubleshooting

HTTPS not working after enabling Cloudflare force HTTPS?

• Check if nginx listens on port 443
• Verify SSL certificates are mounted correctly
• Ensure Cloudflare Tunnel service URL matches (http:// or https://)

Data lost after container restart?

• Check docker-compose.yml uses named volumes, not bind mounts for critical data
• Verify database path points to mounted volume directory
