Docker Deployment with Nginx HTTPS

Quick Start

For Docker web application deployment with HTTPS support:

•Configure Nginx with SSL certificates (see nginx-https.md)
•Set up docker-compose.yml with certificate volume mounting
•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

code

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
