How to Install and Configure Magento 2 Docker

1. Build a project by using Composer.

To start setting up Magento 2, the first step is to create a directory. After that, you can proceed with running the code below:

composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition <install-directory-name>

The provided command above will install the most recent release of Magento. If you wish to install a particular version of Magento, input the corresponding version number. For instance:

magento/project-community-edition=2.4.2

2. Switch to the Project directory.

For <install-directory-name>, you might have given a name like example.com. Navigate to the project directory on the server before executing the next set of instructions. cd <install-directory-name>

3. Include the ece-tools and Cloud Docker in the setup.

Cloud Docker allows easy deployment of Magento 2.4 in a Docker environment, serving purposes like development, testing, and automation. To include the ece-tools and cloud docker for community packages, execute the command b. composer require --no-update --dev magento/ece-tools magento/magento-cloud-docker

4. Create a default configuration source file

We now generate the default configuration source file called .magento.docker.yml. This file is utilized to construct the Docker containers for the local environment.

Here's the configuration for Magento 2: -

system:
    mode: 'production'
services:
    php:
        version: '7.4'
        extensions:
            enabled:
                - xsl
                - json
                - redis
    mysql:
        version: '10.4'
        image: 'mariadb'
    redis:
        version: '6.0'
        image: 'redis'
    elasticsearch:
        version: '7.9.0'
        image: 'magento/magento-cloud-docker-elasticsearch'
hooks:
    build: |
        set -e
        php ./vendor/bin/ece-tools run scenario/build/generate.xml
        php ./vendor/bin/ece-tools run scenario/build/transfer.xml
    deploy: 'php ./vendor/bin/ece-tools run scenario/deploy.xml'
    post_deploy: 'php ./vendor/bin/ece-tools run scenario/post-deploy.xml'
mounts:
    var:
        path: 'var'
    app-etc:
        path: 'app/etc'
    pub-media:
        path: 'pub/media'
    pub-static:
        path: 'pub/static'
        

5. Use the Magento Installation Script

During installation, the script will include the necessary template dependencies and set up the default hostname in your /etc/hosts file.

curl -sL https://github.com/magento/magento-cloud-docker/releases/download/1.2.3/init-docker.sh | bash -s -- --php 7.4

6. Update the project dependencies

To update the project dependencies, use the following command:

composer update

7. Generate the Docker Compose Configuration file

./vendor/bin/ece-docker build:compose --mode="developer"

Once the script finishes, you'll come across a file named docker-compose.yml. This file serves as the configuration file for Docker Compose.

Occasionally, the docker image may be generated improperly. Modifying and rectifying the file based on the corresponding Magento version is necessary in such cases. Additionally, please update the Tags image version on the Magento Docker hub.

8. Add auth.json file

To access the Magento Marketplace, first log in to your account. Then, navigate to your profile and choose the option for Access Keys. If needed, you can also create a new access key.

The and must be accessible from the panel. Create a file named auth.json with the following content in your project directory:

   {
    "http-basic": {
        "repo.magento.com": {
            "username": "<public-key>",
            "password": "<private-key>"
        }
    }
}
    

9. Build files to the container.

To build files into the container and run them in the background, use the command below: docker-compose up -d

10. Deploy Magento as a Docker container

docker-compose run --rm deploy cloud-deploy
docker-compose run --rm deploy magento-command deploy:mode:set developer
docker-compose run --rm deploy cloud-post-deploy
    

11. Configure and Connect Varnish

Next, set up varnish and connect it with Magento.

docker-compose run --rm deploy magento-command config:set system/full_page_cache/caching_application 2 --lock-env
    
docker-compose run --rm deploy magento-command setup:config:set --http-cache-hosts=varnish
    

12. Clear the Cache

To complete the process, clear the cache and verify the results. Use the command below to clear the cache:

docker-compose run --rm deploy magento-command cache:clean
    

Access the local Magento Cloud template using Magento 2 docker.

Log in to the Admin panel using the default credentials:

• Username = Admin

• Password = 123123qWe have finished installing Magento 2 Docker and can now use it on any operating system.

Tips to Optimize Docker Performance with Magento 2

Optimizing Docker performance with Magento 2 is crucial for smooth and efficient development. Here are some helpful tips to enhance your Docker setup:

• Use a lightweight base image: Choose a minimalistic and optimized Docker base image specific to Magento 2. This reduces the container's size and improves startup time.

• Optimize caching mechanisms: Use Redis for Magento's full-page cache, session storage, and metadata caching. This significantly enhances performance by reducing database queries.

• Adjust memory limits: Allocate sufficient memory resources to your Docker containers based on the requirements of Magento 2 and any Magento extensions or modules being used.

• Implement volume mounting strategies: Mount frequently accessed directories such as pub/media, var/log, var/session, etc., as separate volumes outside the container for better I/O performance.

• Enable OPCache: Configure PHP's OPCache extension to store precompiled script bytecode in shared memory, resulting in faster execution times.

• Fine-tune MySQL settings: Modify MySQL configuration parameters like innodb_buffer_pool_size, key_buffer_size based on your application needs to optimize database performance.

• Monitor resource utilization: Use tools like Grafana or Prometheus to regularly track CPU, memory usage, and disk I/O metrics to identify bottlenecks and make necessary adjustments.

By optimizing your Docker environment for Magento 2 development, you can improve performance and efficiency throughout the development lifecycle.
