Dockerized WordPress Setup for Beginners: Step-by-Step

Running WordPress on Docker is one of the easiest ways to create a portable, scalable, and consistent development or production environment.

Instead of installing PHP, MySQL, and Apache/Nginx manually, Docker allows you to containerize everything and run WordPress with just a few commands.

This guide will walk beginners through setting up a Dockerized WordPress environment using Docker and Docker Compose.

Why Use Docker for WordPress?

• ⚡ Quick Setup – Run WordPress in minutes without complex server configuration.

• 🔒 Isolated Environment – Avoid conflicts with existing software on your machine.

• 🔄 Portability – Move your entire setup between machines or cloud providers easily.

• 📦 Scalability – Perfect for local development, testing, or even production.

Prerequisites

Before starting, make sure you have:

• Docker Desktop installed (Windows, macOS, or Linux).

• Docker Compose (comes with Docker Desktop by default).

• Basic knowledge of command-line usage.

Step 1: Create a Project Directory

Step 2: Create a docker-compose.yml File

Inside your project folder, create a file named docker-compose.yml:

version: '3.9'

services:
  wordpress:
    image: wordpress:latest
    ports:
      - "8080:80"
    environment:
      WORDPRESS_DB_HOST: db
      WORDPRESS_DB_USER: wordpress
      WORDPRESS_DB_PASSWORD: wordpress
      WORDPRESS_DB_NAME: wordpress
    volumes:
      - ./wp-data:/var/www/html

  db:
    image: mysql:5.7
    environment:
      MYSQL_DATABASE: wordpress
      MYSQL_USER: wordpress
      MYSQL_PASSWORD: wordpress
      MYSQL_ROOT_PASSWORD: rootpassword
    volumes:
      - ./db-data:/var/lib/mysql

  phpmyadmin:
    image: phpmyadmin/phpmyadmin
    ports:
      - "8081:80"
    environment:
      PMA_HOST: db
      MYSQL_ROOT_PASSWORD: rootpassword

Explanation:

• WordPress container runs the WordPress site.
• MySQL container stores your WordPress database.
• phpMyAdmin container lets you manage the database via a web UI.

Step 3: Start the Containers

Run the following command inside your project folder:

• WordPress will be available at: http://localhost:8080

• phpMyAdmin will be available at: http://localhost:8081

Step 4: Install WordPress

1. Open http://localhost:8080 in your browser.

2. Choose your language.

3. Enter site details (title, username, password, email).

4. Complete the installation.

You now have a fully working Dockerized WordPress site! 🎉

Step 5: Manage Your Containers

• Stop containers:

  docker-compose down


• Restart containers:

  docker-compose up -d


• Check logs:

  docker-compose logs -f


Optional: Persistent Data

In the example above, WordPress files are stored in ./wp-data and database files in ./db-data. This ensures your content and database survive container restarts.

Best Practices for Beginners

• Always use volumes to persist your data.

• Keep your docker-compose.yml file under version control (e.g., Git).

• Use different ports if running multiple WordPress instances.

• For production, consider using Docker Swarm or Kubernetes.

FAQ

1. Do I need coding skills to use Docker for WordPress?
Not much — basic command-line knowledge is enough.

2. Can I use Dockerized WordPress for production?
Yes, but it’s more common for local development. For production, add reverse proxy, SSL, and backups.

3. How do I access my WordPress database?
Use phpMyAdmin at http://localhost:8081 or connect via MySQL client.

4. Can I run multiple WordPress sites with Docker?
Yes, just create separate project directories with unique ports.

5. What happens if I delete the containers?
Your site will remain intact if you use volumes (wp-data, db-data).
