Automated Secure Hosting with Cloudflare Tunnel & Docker

#docker #cloudflare #devops #selfhosted

πŸ“– This article is a translation of the original post published on ITpraktika.com (Bulgarian).

If you own a server β€” whether a VPS or a home machine β€” and want to host websites or monitoring tools, security and configuration can quickly become a headache. This post introduces a single Bash script that handles everything for you: from generating strong passwords to spinning up a fully isolated Docker environment.

πŸ›‘οΈ What Does This Script Do?

This tool is built for people who want a professional-grade setup with minimal effort. It automates:

  • Cloudflare Tunnel β€” Connects your server to Cloudflare's network without opening ports 80 or 443 on your router or firewall. Your server stays invisible to bots and scanners.
  • Uptime Kuma β€” Installs one of the best open-source monitoring tools for tracking your sites and services.
  • WordPress support β€” Optionally spins up to 2 independent WordPress sites, each with its own isolated database.
  • Maximum security β€” Generates unique 24-character passwords for every component and sets proper file permissions on all config files.
  • Healthchecks β€” Intelligently waits for MariaDB to be fully ready before starting your sites, preventing startup race conditions.

πŸ› οΈ How to Use It

The entire setup takes less than a minute. SSH into your Linux server and run these three commands:

1. Download the script:

wget https://gist.fedia.eu/urocibg/8edf74d152594176a1052308054ed36c/raw/HEAD/setup_hosting.sh
Enter fullscreen mode Exit fullscreen mode

2. Make it executable:

chmod +x setup_hosting.sh
Enter fullscreen mode Exit fullscreen mode

3. Run the installer:

./setup_hosting.sh
Enter fullscreen mode Exit fullscreen mode

πŸ“‹ What Happens Next?

The script will ask you a few questions β€” whether you want Uptime Kuma, how many WordPress sites you need, and your Cloudflare tunnel token. Once you answer, it generates:

  1. An .env file containing all your passwords.
  2. A docker-compose.yml with optimized settings.
  3. An initialization SQL script for your databases.

Once you've answered all the questions, the script takes care of the rest β€” including starting all the containers. Your entire infrastructure will be online automatically. πŸŽ‰

Note: This script is an ideal solution for developers and sysadmins looking for the right balance between cost, security, and ease of maintenance.
