How to Install WordPress with Docker Compose

WordPress is a powerful and popular content management system (CMS) used by millions of websites. Docker Compose simplifies the process of setting up a WordPress environment by handling WordPress and its dependencies in containers. This guide will walk you through installing WordPress with Docker Compose.

Step 1: Install Docker and Docker Compose

First, ensure that Docker and Docker Compose are installed on your server. You can install Docker and Docker Compose with the following commands:

sudo apt update
sudo apt install docker.io
sudo apt install docker-compose

Step 2: Create a Docker Compose File

Create a directory for your WordPress installation and navigate into it:

mkdir wordpress && cd wordpress

Next, create a docker-compose.yml file. This file will define the services (WordPress and MySQL) that Docker will run:

nano docker-compose.yml

Add the following content to the docker-compose.yml file:

version: '3.3'
services:
  wordpress:
    image: wordpress
    restart: always
    ports:
      - "8080:80"
    environment:
      WORDPRESS_DB_HOST: db
      WORDPRESS_DB_USER: exampleuser
      WORDPRESS_DB_PASSWORD: examplepass
      WORDPRESS_DB_NAME: exampledb
    volumes:
      - ./wordpress:/var/www/html

  db:
    image: mysql:5.7
    restart: always
    environment:
      MYSQL_DATABASE: exampledb
      MYSQL_USER: exampleuser
      MYSQL_PASSWORD: examplepass
      MYSQL_ROOT_PASSWORD: rootpassword
    volumes:
      - ./db_data:/var/lib/mysql

Step 3: Start WordPress

Now, you can start your WordPress and MySQL containers using Docker Compose. Run the following command to pull the necessary images and start the services:

sudo docker-compose up -d

This will download the WordPress and MySQL images and start the containers in the background.

Step 4: Access WordPress

After the containers are up and running, you can access your WordPress site by visiting http://your_server_ip:8080 in a web browser. You will see the WordPress installation screen, where you can choose your language and proceed with the setup.

Step 5: Configure WordPress

Follow the on-screen instructions to complete the WordPress installation:

• Enter the site title
• Create an admin username and password
• Provide your email address

Once the setup is complete, you can log in to your WordPress admin dashboard.

Step 6: Manage Containers

To check the status of your containers, you can use the following command:

sudo docker-compose ps

To stop the WordPress and MySQL containers, use:

sudo docker-compose down

Conclusion

Congratulations! You have successfully installed WordPress using Docker Compose on your server. Docker Compose makes it easy to manage and deploy WordPress along with its dependencies in a containerized environment. With your WordPress site up and running, you can start creating content and managing your site.
