Docker compose for Magento2 installed in an unattended way

Docker Environment

To use the docker environment clone this repo inside a folder structure like this:

some_directory <- Name is not important
  |- src <- An empty folder to be used in the automatic installation process

And copy this repo's docker-compose.yml & build.sh & .env files to the root of the base directory (some_directory in the example) so you'll have:

some_directory <- Name is not important
  |- src <- An empty folder to be used in the automatic installation process
  |- docker-compose.yml
  |- build.sh
  |- .env

Edit the copy of .env and set your tokens in the COMPOSER_AUTH environment variable. You can also set the version of Magento you wish to install.

Then run the environment by executing:

$ docker-compose up

from the base directory where the copy of docker-compose.yml is located. The installation process will take some minutes to be finished. You can follow the status logging with:

docker logs setup -f

Finally, Magento 2 with the module installed will be running at http://localhost:80.

The admin panel will be available at http://localhost:80/admin. Admin credentials are easy:

User: admin
Pass: admin123

To install sample data, with the containers running:

$ docker exec -u root -it web bash
root@...:~# cd /app
root@...:/app# gosu application php -d memory_limit=-1 ./bin/magento sampledata:deploy
root@...:/app# gosu application php -d memory_limit=-1 ./bin/magento setup:upgrade

Exposing the server to internet

To expose our local server to internet we can use, for example; the utility Ngrok: https://dashboard.ngrok.com/get-started/setup

Once we have the external ip created (and before running the docker-compose up) simply edit the .env file and set the MAGENTO_BASE_URL=ip (for example: MAGENTO_BASE_URL=7dd5-80-26-218-151.ngrok.io)

So, when the installation process finished, instead of accessing to http://localhost:80 we will use: http://ip:80 (for example: https://7dd5-80-26-218-151.ngrok.io).

Xdebug ready to use

If you wish to debug your new Magento installation, just simply set the correct values in .env and configure your IDE attending to the remote PHP docker container web. You should also bind your local source path: ./src to the docker one: /app

Last notes

Please, take care when you change in .env the MAGENTO_VERSION parameter since you'll have to change probably the PHP_VERSION & COMPOSER_VERSION ones in order to maintain the compatibility. For example, if you wish the Magento 2.4.3 version you should have:

PHP_VERSION=7.4
COMPOSER_VERSION=2.0.14
MAGENTO_EDITION=community
MAGENTO_VERSION=2.4.3

but if you want to test, let's say, the 2.3.1 version you should have something like this:

PHP_VERSION=7.2
COMPOSER_VERSION=1.4.3
MAGENTO_EDITION=community
MAGENTO_VERSION=2.3.1

And please, don't forget to copy in .env your Magento repository tokens filling the parameters:

COMPOSER_AUTH_USERNAME=
COMPOSER_AUTH_PASSWORD=
