That’s all the prerequisites. Let’s explore 3 important Magento 2 docker setup steps !

Step 1: Generate a docker-composer.yml file

#1. You need to select a place to put your Docker configuration files. Refer this location as /path/to/docker.

#2. Next, open a new document.

#3. Now, click on “copy” and paste the following code into a new file:

version: '3'
       image: webdevops/php-apache-dev:ubuntu-16.04
       container_name: web
       restart: always
       user: application
         - WEB_DOCUMENT_ROOT=/app/pub
         - PHP_MEMORY_LIMIT=2048M
         - PHP_POST_MAX_SIZE=500M
         - /path/to/magento:/app:cached
         - "80:80"
         - "443:443"
         - "32823:22"
         - mysql
       image: mariadb:10
       container_name: mysql
       restart: always
         - "3306:3306"
         - MYSQL_ROOT_PASSWORD=root
         - MYSQL_DATABASE=magento
         - db-data:/var/lib/mysql
       container_name: phpmyadmin
       restart: always
       image: phpmyadmin/phpmyadmin:latest
         - MYSQL_ROOT_PASSWORD=root
         - PMA_USER=root
         - PMA_PASSWORD=root
         - "8080:80"
         - mysql:db
         - mysql
       external: false

#4. Navigate to line 8 and replace the domain name with the created domain before.

#5. On line 17, please replace /path/to/magento with the absolute path to the Magento files that you have downloaded before.

#6. Finally, in step 1, remember to save the new file as /path/to/docker/docker-compose.yml.

Step 2: Ready to start with your virtual machine

#1. In this step, you still need to open your terminal to /path/to/docker.

#2. It’s time to fire up your virtual machine. As soon as you spin up, it takes some minutes so that Dockers can download the images. After that, spin-ups in the future will take a few seconds.

docker-compose up -d --build

#3. Please make sure that everything is set up and run as per your plan. Then, you need to go to in your web browser, and you will see phpMyAdmin. Congrats, it’s successful if you can see it.

Step 3: Install Magento 2 in detail

It’s time to do the most important step in Magento 2 Docker setup. Let’s get going!

#1. Access your command line that contains your Docker web: docker exec -it web bash

#2. Please go ahead to the web document root: cd /app

#3. Although this is an optional step, highly recommended: deploy sample data: php bin/magento sampledata:deploy

#4. Install Magento 2. Remember to copy and paste the following command into the Docker terminal. Note that you must replace the values on lines 2-6 with your details. On lines 7-8, please replace the placeholder domain with your created domain name before.

php bin/magento setup:install \
--admin-firstname=John \
--admin-lastname=Doe \
[email protected] \
--admin-user=admin \
--admin-password='SomePassword123' \
--base-url= \
--base-url-secure= \
--backend-frontname=admin \
--db-host=mysql \
--db-name=magento \
--db-user=root \
--db-password=root \
--use-rewrites=1 \
--language=en_US \
--currency=USD \
--timezone=America/New_York \
--use-secure-admin=1 \
--admin-use-security-key=1 \
--session-save=files \

#5. Navigate to your website at or whatever domain you select. You need to spend some minutes loading the page when you access the website for the first time. The reason for this is that nothing is cached and the Magento system will automatically create files when loading the pages. Don’t worry, as the loading process will be quicker next time.

Additionally, as the web container applies a self-signed SSL certificate, you can get a security alert from the browser when visiting the URL for the first time.

#6. Congratulations! You succeeded in setting up Magento 2 on Docker. Please remember that you can repeat this process for other projects through our step-by-step guide.

While the benefits of running Magento 2 on Docker are numerous, mastering some key details and commands can take your project to the next level. Here’s a concise guide to essential Docker information and commands for a smooth experience:

1. Docker Information

  • Docker Data Persistence: Even after you restart the virtual machine, your database will remain unchanged. This is because the docker-compose.yml file contains a data volume.
  • Database Access: Need to connect to other databases or tools like Sequel Pro? Simply access your Magento database at using the credentials username: root, password: root, database name: magento.

2. Docker Commands

  • Spin Up: docker-compose up -d --build
  • Tear Down: docker-compose down
  • Web Container CLI Access: docker exec -it web bash
  • Database Container CLI Access: docker exec -it mysql bash
