Docker & HTTPS

Running Docker containers over HTTPS is beneficial for simulating real-world scenarios, providing more realistic Proof-of-Concept (POC) environments without browser warnings about insecure HTTP data transfer.

Steps to Set Up Docker with HTTPS

1. Set Up Docker Containers

   • Run Nginx Proxy Manager:
     • Configure default ports as needed.
     • Add volumes:
       • ./data:/data
       • ./letsencrypt:/etc/letsencrypt
   • Run Your Application Docker Container:
     • Assign any preferred port.

2. Domain Setup

   • Choose a domain to use for demonstration purposes.
   • Update the server name in your DNS settings to use Cloudflare.
   • In Cloudflare, add a new A record for the desired subdomain, pointing it to your local machine's IP. Disable Cloudflare's proxy setting for this record.

3. Configure Nginx Proxy Manager

   • Access Nginx Proxy Manager and create a new host with the following settings:
     • Protocol: HTTP
     • IP Address: Local machine IP (e.g., 192.168.2.x)
     • Port: Specify the application's port
     • Enable WebSocket support
     • Set up an SSL certificate using your Cloudflare API key.

4. Finalize Setup

   • Wait for DNS propagation from Cloudflare. Once completed, your Docker setup should be accessible over HTTPS without warnings.
