✨Automate WordPress + MySQL Deployment Using Docker Compose & OpenTofu on Server

[MyrinNew]

💡 Introduction

OpenTofu is an open-source fork of Terraform.

It allows full automation of server provisioning even in your local machine—not just cloud infrastructure.


In this guide, we automate:

• Docker installation
• Docker Compose installation
• Creating volumes + networks
• Deploying a full WordPress + MySQL stack
• Starting the containers

All using OpenTofu and null_resource.


This is perfect for:

• DevOps practice
• Local development setup
• CI/CD environments
• Rapid application testing

🔧 Prerequisites

Ubuntu machine (local, VM, or cloud)


Install OpenTofu:






sudo apt update -y
sudo apt upgrade -y
sudo snap install --classic opentofu










📁 Project Setup





mkdir tofu-docker-wordpress
cd tofu-docker-wordpress
nano main.tf










🧱 OpenTofu Code (main.tf)





terraform {
required_providers {
null = {
source = "hashicorp/null"
}
}
}
