Download Magento 2

You need to access Mageplaza to download Magento 2.
After logging in, navigate to Access Keys, and this time, please keep that window open because the keys are necessary for step 3.
Decide a location on your local machine that you want to put the website files to live.
Please open a command line terminal window. Please replace the placeholder path with the final path where you will install Magento, before copying and pasting the code below.

cd /path/to/where/you/will/download/magento && \
composer create-project --repository-url=https://repo.magento.com/ 
magento/project-community-edition

Please choose the version you want and press the download button. Afterward, you will be redirected to the directory where you installed the Magento, /path/to/magento.
At this point, please increase the PHP memory limit from the default value of 765M to 2048M.
Finally, select a domain name that you would like to access the site, then add it to your host’s file.

sudo -- sh -c "echo '127.0.0.1 local.domain.com' >> /etc/hosts"

That’s all the prerequisites. Let’s explore 3 important 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'
services:
   web:
       image: webdevops/php-apache-dev:ubuntu-16.04
       container_name: web
       restart: always
       user: application
       environment:
         - WEB_ALIAS_DOMAIN=local.domain.com
         - WEB_DOCUMENT_ROOT=/app/pub
         - PHP_DATE_TIMEZONE=EST
         - PHP_DISPLAY_ERRORS=1
         - PHP_MEMORY_LIMIT=2048M
         - PHP_MAX_EXECUTION_TIME=300
         - PHP_POST_MAX_SIZE=500M
         - PHP_UPLOAD_MAX_FILESIZE=1024M
       volumes:
         - /path/to/magento:/app:cached
       ports:
         - "80:80"
         - "443:443"
         - "32823:22"
       links:
         - mysql
   mysql:
       image: mariadb:10
       container_name: mysql
       restart: always
       ports:
         - "3306:3306"
       environment:
         - MYSQL_ROOT_PASSWORD=root
         - MYSQL_DATABASE=magento
       volumes:
         - db-data:/var/lib/mysql
   phpmyadmin:
       container_name: phpmyadmin
       restart: always
       image: phpmyadmin/phpmyadmin:latest
       environment:
         - MYSQL_ROOT_PASSWORD=root
         - PMA_USER=root
         - PMA_PASSWORD=root
       ports:
         - "8080:80"
       links:
         - mysql:db
       depends_on:
         - mysql
 
volumes:
   db-data:
       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 127.0.0.1.8080 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. 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 copying and pasting the following command into the Docker terminal. Note that you must replace the values on lines 2-6 with your own 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 \
--admin-email=johndoe@example.com \
--admin-user=admin \
--admin-password='SomePassword123' \
--base-url=https://local.domain.com \
--base-url-secure=https://local.domain.com \
--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 \
--use-sample-data

#5. Navigate to your website at https://local.domain.com 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 succeed in setting up Magento 2 on Docker. Please remember that you can repeat this process for other projects through our step-by-step guide.
