How to Install WordPress with Docker Compose

To install WordPress with Docker Compose, you will need to have Docker and Docker Compose installed on your system.

Create a new directory for your WordPress project, and navigate to it in the terminal.

Create a docker-compose.yml file in the project directory and add the following configuration:

version: '3'

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

  wordpress:
    depends_on:
      - db
    image: wordpress:latest
    ports:
      - "8080:80"
    restart: always
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_USER: wordpress
      WORDPRESS_DB_PASSWORD: wordpress
      WORDPRESS_DB_NAME: wordpress
volumes:
  db_data:

This configuration file specifies two Docker containers: one for the MySQL database, and one for WordPress. It also defines a volume for the MySQL data to ensure that it is persisted even if the container is stopped or removed.

Run the following command to start the containers:

docker-compose up -d

This will download the necessary images and start the containers in the background.

4. Open a web browser and go to http://localhost:8080 to complete the WordPress installation. You will be prompted to enter your database details, which should be as follows:

• Database name: wordpress
• User name: wordpress
• Password: wordpress
• Host: db

5. Follow the on-screen instructions to complete the installation.

That’s it! You should now have WordPress installed and running in Docker using Docker Compose.
