CMS Setup - WordPress with Docker

In this section, I’ll walk you through the complete setup process of WordPress using Docker. This includes starting the necessary containers (WordPress and MySQL), configuring volumes, and verifying everything works.

Step-by-Step setup Instructions

Create a project Directory

Create a folder for your WordPress project to keep things organized.

mkdir wordpress-docker
cd wordpress-docker

Create a docker-compose.yml File

Inside your project folder, create a file named docker-compose.yml with the following content:

version: '3.9'

services:
  db:
    image: mysql:5.7
    container_name: wordpress-db
    restart: always
    environment:
      MYSQL_DATABASE: wordpress
      MYSQL_USER: wp_user
      MYSQL_PASSWORD: wp_pass
      MYSQL_ROOT_PASSWORD: root_pass
    volumes:
      - db_data:/var/lib/mysql

  wordpress:
    image: wordpress:latest
    container_name: wordpress-app
    depends_on:
      - db
    ports:
      - "8000:80"
    restart: always
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_NAME: wordpress
      WORDPRESS_DB_USER: wp_user
      WORDPRESS_DB_PASSWORD: wp_pass
    volumes:
      - wordpress_data:/var/www/html

volumes:
  db_data:
  wordpress_data:

What this does:

  • Build and runs MySQL and WordPress containers
  • Maps port 8000 on your machine to port 80 in the WordPress container
  • Uses environment variables to set up the WordPress connection to MySQL

Run the Containers

Start everything using Docker Compose:

docker-compose up -d

You should see output indicating that both containers are up and running.

Open WordPress in Your Browser

Visit http://localhost:8000 in your browser.

You should see the WordPress installation screen:

Follow the installation wizard to set your site title, admin user, and password.

Troubleshooting Tips

If you encounter issues, check the following:

  • Use docker ps to verify containers are running.
  • Use docker-compose logs to view detailed logs.
  • Make sure port 8000 isn’t in use by another service.
  • Rebuild with docker-compose down -v && docker-compose up -d to reset everything.
