How to Configure Magento 2.4 with Docker

Setting up Magento 2.4 with Docker can be a game-changer for developers and businesses looking for a flexible and scalable e-commerce solution. Docker allows you to encapsulate the entire Magento environment, making it easy to deploy, manage, and scale your online store. In this article, we will guide you through the process of configuring Magento 2.4 with Docker, providing step-by-step instructions and useful commands to ensure a smooth setup.

1. Prerequisites:
   Before diving into the configuration process, ensure you have Docker and Docker Compose installed on your system. You can download them from the official Docker website (https://www.docker.com/). Additionally, make sure you have Git installed for easy retrieval of Docker configurations.

2. Clone Magento Repository:
   Open your terminal and use the following command to clone the official Magento repository from GitHub:

   git clone https://github.com/magento/magento2.git
   

3. Create Docker Compose File:
   Navigate to the Magento directory and create a docker-compose.yml file for defining your Docker services. Here's a basic example to get you started:

   version: '3'
   services:
     web:
       image: nginx:alpine
       ports:
         - "80:80"
     php:
       image: php:7.4-fpm
     db:
       image: mysql:5.7
       environment:
         MYSQL_DATABASE: magento
         MYSQL_USER: magento
         MYSQL_PASSWORD: magento
         MYSQL_ROOT_PASSWORD: root
   

4. Magento Configuration:
   Inside the Magento directory, copy the env.php.dist file to env.php. Open env.php and configure your database connection settings:

   'db' => [
       'connection' => [
           'default' => [
               'host' => 'db',
               'dbname' => 'magento',
               'username' => 'magento',
               'password' => 'magento',
               'model' => 'mysql4',
               'engine' => 'innodb',
               'initStatements' => 'SET NAMES utf8;'
           ]
       ]
   ],
   

5. Build and Run Docker Containers:
   Execute the following commands to build and run your Docker containers:

   docker-compose up -d --build
   

6. Install Magento:
   Access the Magento container and run the setup commands to install Magento:

   docker exec -it <magento_container_id> /bin/bash
   bin/magento setup:install --base-url=http://localhost/ \
   --db-host=db --db-name=magento --db-user=magento --db-password=magento \
   --admin-firstname=admin --admin-lastname=admin --admin-email=admin@example.com \
   --admin-user=admin --admin-password=admin123 --language=en_US --currency=USD \
   --timezone=America/New_York --use-rewrites=1
   

More Examples:

• Useful Commands:

  • To stop containers: docker-compose down
  • To view container logs: docker-compose logs

• Scaling Magento:

  • Docker allows easy scaling. Use the --scale flag with docker-compose to run multiple instances of a service, e.g. docker-compose up -d --scale web=2.
