🚀 Faster than traditional setups – No manual Apache/MySQL/PHP configs.
🔒 Isolated containers – No conflicts with other dev environments.
📦 Reproducible deployments – Same setup works on any machine.
Easy scaling – Need Redis or Nginx? Just add a service.


Prerequisites

Before starting, ensure you have:

  • Docker installed (Download Docker)
  • Docker Compose (included with Docker Desktop)
  • Basic terminal knowledge (you’ll run a few commands)

Step 1: Create a docker-compose.yml File

Create a new directory for your project and add this optimized docker-compose.yml:

Key Optimizations in This Setup:

🔹 Persistent volumes (db_data, wp_data) – Prevents data loss on container restart.
🔹 Isolated network – Improves security by separating WordPress & MySQL.
🔹 Latest stable versions – Uses MySQL 8.0 and WordPress latest.

Step 2: Launch WordPress with Docker Compose

Run this command in your project directory:

  • -d runs containers in the background (detached mode).
  • Wait ~30 seconds for MySQL to initialize.

Access WordPress:
👉 Open http://localhost:8000 in your browser.
