We hope this post helped you to find out  How to Install and Use Docker Compose on Debian 10

Docker is a containerization platform that means that you can rapidly construct, check, and deploy functions as transportable, self-sufficient containers that may run nearly wherever.

Docker Compose is a instrument that means that you can outline and orchestrate multi-container Docker functions. It makes use of a YAML file to configure the applying’s containers, networks, and volumes.

Compose can be utilized for numerous functions. Single host utility deployments, automated testing, and native growth are the most well-liked use instances for Docker Compose.

This tutorial explains the way to set up the most recent model of Docker Compose on Debian 10, Buster. We’ll additionally discover the essential Docker Compose ideas and instructions.

Stipulations #

Earlier than you proceed, just be sure you have met the next conditions:

Step 1. Installing in Docker Compose on Debian 10 #

The Docker Compose set up bundle is out there within the official Debian 10 repositories, however it might not at all times be the most recent model. The really useful method is to put in Docker Compose from the Docker’s GitHub repository.

On the time of writing this text, the most recent secure model of Docker Compose is model 1.23.1. Earlier than downloading the Compose binary, go to the Compose repository release page on GitHub and examine if there’s a new model obtainable for obtain.

Use the following steps to install the latest version of Docker Compose on Debian 10:

Step 2. Download the Docker Compose binary into the /usr/local/bin directory with

wget or curl: sudo curl -L "https://github.com/docker/compose/releases/download/1.23.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

Step 3. Use chmod to make the Compose binary executable:

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

Step 4. To verify the installation, use the following command which prints the Compose version:

docker-compose --version

The output will look something like this:

docker-compose version 1.23.1, build b02f1306

Step 5. Getting Started with Docker Compose #

In this section, we will show how to set up a local WordPress development environment with Docker Compose.

Create a directory for the project and navigate into it:

mkdir wordpress_app && cd wordpress_app

Open your text editor and create a file named docker-compose.yml:

nano docker-compose.yml

Paste the following content:

docker-compose.yml
version: '3.7'

services:
  db:
    image: mysql:8.0
    command: --default-authentication-plugin=mysql_native_password
    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:

Let’s explain the code line by line

The primary line specifies the Compose file version. There are a number of completely different variations of the Compose file format with help for particular Docker releases.

Subsequent, we’re defining two companiesdb and wordpress. Every service creates a separate container when Docker Compose is run.

The db service:

  • The picture is ready to mysql:8.0 picture. If the picture will not be current, Compose will pull it from the Docker Hub public repository. The road beginning with command overrides the default command.
  • The restart: at all times coverage instructs Compose to restart the container if it goes down.
  • The container will use a named quantity db_data to persist the database.
  • Defines the surroundings variables for the mysql:8.0 picture.

The wordpress service:

  • Makes use of the wordpress picture.
  • Mounts the wp_data listing on the host to /var/lib/mysql contained in the container.
  • Forwards the uncovered port 80 on the container to port 8080 on the host machine.
  • Defines the surroundings variables for the wordpress picture.
  • The depends_on instruction defines the dependency between the 2 companies. On this instance, db shall be began earlier than wordpress.

From the undertaking listing, begin up the WordPress stack by operating the next command:

docker-compose up

The output should look something like this:

...
] /usr/sbin/mysqld: ready for connections. Version: '8.0.18'  socket: '/var/run/mysqld/mysqld.sock'  port: 3306  MySQL Community Server - GPL.
db_1_99946702ac7e | 2019-12-15T21:37:29.109255Z 0 [System] [MY-011323] [Server] X Plugin ready for connections. Socket: '/var/run/mysqld/mysqlx.sock' bind-address: '::' port: 33060
...

Docker Compose will pull the photographs, begin the containers, and create the wp_data listing in your undertaking listing.

Enter http://0.0.0.0:8080/ in your browser, and you will note the usual WordPress set up display screen.

At this level, the WordPress utility is up and operating, and you can begin engaged on it.

To cease Compose press CTRL+C.

You may as well begin the Compose in a indifferent mode by utilizing the -d choice:

docker-compose up -d

To view the running docker containers use the following command:

docker-compose ps
                 Name                               Command               State          Ports        
------------------------------------------------------------------------------------------------------
wordpress_app_db_1_99946702ac7e          docker-entrypoint.sh --def ...   Up      3306/tcp, 33060/tcp 
wordpress_app_wordpress_1_a428d8408817   docker-entrypoint.sh apach ...   Up      0.0.0.0:8080->80/tcp 

To stop the services when Compose is running in detached mode, use:

docker-compose stop

If you want to remove the containers entirely use the down option:

docker-compose down

Passing the --volumes switch also remove the data volumes:

docker-compose down --volumes

Uninstalling Docker Compose #

If you need to uninstall Docker Compose you can simply remove the binary by typing:

sudo rm /usr/local/bin/docker-compose

Conclusion #

To put in Docker Compose on a Debian 10, merely obtain the binary in a listing within the system path and make it executable.
