Introduction

What is Demyx?#

Demyx is a Docker image that automates WordPress installations. It handles the full stack — from reverse proxy with automatic SSL/TLS via Traefik, to WordPress container management with NGINX-PHP or OpenLiteSpeed, plus MariaDB.

You manage everything through a single unified CLI: demyx.

Features#

• Automated WordPress — spin up a new site with one command: demyx run domain.tld --ssl
• Multiple stacks — choose between NGINX-PHP, OpenLiteSpeed, Bedrock, or OLS-Bedrock per app
• Automatic SSL — Traefik handles Let's Encrypt certificates with zero configuration
• One-command backups — demyx backup all backs up every app's files and database
• Healthchecks — built-in monitoring for app containers, disk usage, and load average with optional email/SMTP notifications
• PHP management — switch PHP version per app, configure PHP-FPM process manager
• Redis & cache — enable FastCGI cache or Redis with a single flag
• SFTP access — per-app SFTP with auto-assigned ports
• WP-CLI — run WP-CLI commands inside any app container via demyx wp domain.tld
• Developer mode — code-server (VS Code in browser) per app with demyx config domain.tld --dev

Requirements#

• A Linux server (Ubuntu 24.04+ recommended)
• Docker installed
• A domain name pointing to your server's IP
• Port 80 and 443 open in your firewall

Architecture#

Internet → Traefik (reverse proxy + SSL) → NGINX/OLS → WordPress (PHP-FPM) → MariaDB

All services run as Docker containers. Demyx orchestrates them through Docker Compose files it generates and manages automatically.
