Build this structure:

• /myfolder/nginx/default.conf
• /myfolder/src/index.php
• /myfolder/docker-compose.yml

Steps:

1. Buy a domain (GoDaddy, Google Domains, ...) and make it point to the public IP of your server
2. On your server (AWS EC2, Azure, ...), build this file structure
3. In docker-compose.yml change alarmsworld.com to your domain name (from GoDaddy, Google Domains, ...)
4. Run docker-compose up -d in /myfolder path
