How to Install and use Docker Compose on Debian 12

Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a Compose file to configure your application's services. Then, using a single command, you create and start all the services from your configuration.

Installing Docker Compose on Ubuntu

Use curl to download the Compose file into the /usr/local/bin directory.

curl -L "https://github.com/docker/compose/releases/download/v2.18.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

Output:

root@server:~# curl -L "https://github.com/docker/compose/releases/download/v2.18.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0

Next, set the correct permissions so that the docker-compose command is executable.

chmod +x /usr/local/bin/docker-compose

To verify that the installation was successful, you can run following command.

docker-compose --version

Output:

root@server:~# docker-compose --version
Docker Compose version v2.18.1

(Optionally) Setting Up a docker-compose.yml File

In this section, we’ll use Docker Compose to construct a multi-container WordPress utility.

creating a new directory in your home folder, and then moving into it.

mkdir my_app

cd my_app

Next, create the docker-compose.yml file.

nano docker-compose.yml

Paste the following content on your docker-compose.yml file.

version: '3'

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

  wordpress:
    image: wordpress
    restart: always
    volumes:
      - ./wp_data:/var/www/html
    ports:
      - "8080:80"
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_NAME: wordpress
      WORDPRESS_DB_USER: root
      WORDPRESS_DB_PASSWORD: password
    depends_on:
       - db

volumes:
    db_data:
    wp_data:

In this example, we have services, db, and wordpress. Each service runs one image, and creates a separate container when docker-compose is run.

Start up the WordPress application by running the following command.

docker-compose up
