Free Course

This course is sponsored by M.academy, the simplest way to learn Magento.

A free screencast course is available (which was fully refreshed in December 2021), which details the basic usage of this project:

Set Up a Magento 2 Development Environment with Docker

Course Curriculm

Intro

Initial Project Setup

The Basics of docker-magento

Docker Filesystem & Data Volumes

PhpStorm

Xdebug

Customize Server Configurations

Usage

This configuration is intended to be used as a Docker-based development environment for Magento 2.

Folders:

images: Docker images for nginx and php
compose: sample setups with Docker Compose

The Magento 1 version of this development environment has been deprecated and is no longer supported. PHP 5 was used as it's base, and that version has reached end-of-life. If you still wish to use this setup, please reference compose/magento-1 on tag 20.1.1, but please be aware these images are no longer maintained.

Prerequisites

This setup assumes you are running Docker on a computer with at least 6GB of RAM allocated to Docker, a dual-core, and an SSD hard drive. Download & Install Docker Desktop.

This configuration has been tested on Mac & Linux. Windows is supported through the use of Docker on WSL.

Setup

Automated Setup (New Project)

# Create your project directory then go into it:
mkdir -p ~/Sites/magento
cd $_

# Run this automated one-liner from the directory you want to install your project.
curl -s https://raw.githubusercontent.com/markshust/docker-magento/master/lib/onelinesetup | bash -s -- magento.test 2.4.4

The magento.test above defines the hostname to use, and the 2.4.4 defines the Magento version to install. Note that since we need a write to /etc/hosts for DNS resolution, you will be prompted for your system password during setup.

After the one-liner above completes running, you should be able to access your site at https://magento.test.

Install sample data

After the above installation is complete, run the following lines to install sample data:

bin/magento sampledata:deploy
bin/magento setup:upgrade

Manual Setup

Same result as the one-liner above. Just replace magento.test references with the hostname that you wish to use.

New Projects

# Create your project directory then go into it:
mkdir -p ~/Sites/magento
cd $_

# Download the Docker Compose template:
curl -s https://raw.githubusercontent.com/markshust/docker-magento/master/lib/template | bash

# Download the version of Magento you want to use with:
bin/download 2.4.4

# or for Magento core development:
# docker-compose -f docker-compose.yml up -d
# bin/setup-composer-auth
# bin/cli git clone git@github.com:magento/magento2.git .
# bin/cli git checkout 2.4-develop
# bin/composer install

# Run the setup installer for Magento:
bin/setup magento.test

open https://magento.test

Existing Projects

# Take a backup of your existing database:
bin/mysqldump > ~/Sites/existing/magento.sql

# Create your project directory then go into it:
mkdir -p ~/Sites/magento
cd $_

# Download the Docker Compose template:
curl -s https://raw.githubusercontent.com/markshust/docker-magento/master/lib/template | bash

# Replace with existing source code of your existing Magento instance:
cp -R ~/Sites/existing src
# or: git clone git@github.com:myrepo.git src

# Start some containers, copy files to them and then restart the containers:
docker-compose -f docker-compose.yml up -d
bin/copytocontainer --all ## Initial copy will take a few minutes...

# Import existing database:
bin/mysql < ../existing/magento.sql

# Update database connection details to use the above Docker MySQL credentials:
# Also note: creds for the MySQL server are defined at startup from env/db.env
# vi src/app/etc/env.php

# Import app-specific environment settings:
bin/magento app:config:import

# Create a DNS host entry and setup Magento base url
bin/setup-domain yoursite.test

bin/restart

open https://magento.test

Updates

To update your project to the latest version of docker-magento, run:

bin/update

We recommend keeping your docker config files in version control, so you can monitor the changes to files after updates. After reviewing the code updates and ensuring they updated as intended, run bin/restart to restart your containers to have the new configuration take effect.

It is recommended to keep your root docker config files in one repository, and your Magento code setup in another. This ensures the Magento base path lives at the top of one specific repository, which makes automated build pipelines and deployments easy to manage, and maintains compatibility with projects such as Magento Cloud.

Custom CLI Commands

bin/bash: Drop into the bash prompt of your Docker container. The phpfpm container should be mainly used to access the filesystem within Docker.
bin/cache-clean: Access the cache-clean CLI. Note the watcher is automatically started at startup in bin/start. Ex. bin/cache-clean config full_page
bin/cli: Run any CLI command without going into the bash prompt. Ex. bin/cli ls
bin/clinotty: Run any CLI command with no TTY. Ex. bin/clinotty chmod u+x bin/magento
bin/cliq: The same as bin/cli, but pipes all output to /dev/null. Useful for a quiet CLI, or implementing long-running processes.
bin/composer: Run the composer binary. Ex. bin/composer install
bin/copyfromcontainer: Copy folders or files from container to host. Ex. bin/copyfromcontainer vendor

bin/xdebug: Disable or enable Xdebug. Accepts params disable (default) or enable. Ex. bin/xdebug enable

Misc Info

Caching

For an improved developer experience, caches are automatically refreshed when related files are updated, courtesy of cache-clean. This means you can keep all of the standard Magento caches enabled, and this script will only clear the specific caches needed, and only when necessary.

To disable this functionality, uncomment the last line in the bin/start file to disable the watcher.

Database

The hostname of each service is the name of the service within the docker-compose.yml file. So for example, MySQL's hostname is db (not localhost) when accessing it from within a Docker container. Elasticsearch's hostname is elasticsearch.

To connect to the MySQL CLI tool of the Docker instance, run:

bin/mysql

You can use the bin/mysql script to import a database, for example a file stored in your local host directory at magento.sql:

bin/mysql < magento.sql

You also can use bin/mysqldump to export the database. The file will appear in your local host directory at magento.sql:

bin/mysqldump > magento.sql

Getting an "Access denied, you need (at least one of) the SUPER privilege(s) for this operation." message when running one of the above lines? Try running it as root with:
bin/clinotty mysql -hdb -uroot -pmagento magento < src/backup.sql
You can also remove the DEFINER lines from the MySQL backup file with:
sed 's/\sDEFINER=`[^`]*`@`[^`]*`//g' -i src/backup.sql

Composer Authentication

First setup Magento Marketplace authentication (details in the DevDocs).

Copy src/auth.json.sample to src/auth.json. Then, update the username and password values with your Magento public and private keys, respectively. Finally, copy the file to the container by running bin/copytocontainer auth.json.

Email / Mailcatcher

View emails sent locally through Mailcatcher by visiting http://{yourdomain}:1080. During development, it's easiest to test emails using a third-party module such as [https://github.com/mageplaza/magento-2-smtp](Mageplaza's SMTP module). Set the mailserver host to mailcatcher and port to 1080.

Redis

Redis is now the default cache and session storage engine, and is automatically configured & enabled when running bin/setup on new installs.

Use the following lines to enable Redis on existing installs:

Enable for Cache:

bin/magento setup:config:set --cache-backend=redis --cache-backend-redis-server=redis --cache-backend-redis-db=0

Enable for Full Page Cache:

bin/magento setup:config:set --page-cache=redis --page-cache-redis-server=redis --page-cache-redis-db=1

Enable for Session:

bin/magento setup:config:set --session-save=redis --session-save-redis-host=redis --session-save-redis-log-level=4 --session-save-redis-db=2

You may also monitor Redis by running: bin/redis redis-cli monitor

For more information about Redis usage with Magento, see the DevDocs.

Xdebug & VS Code

Install and enable the PHP Debug extension from the Visual Studio Marketplace.

Otherwise, this project now automatically sets up Xdebug support with VS Code. If you wish to set this up manually, please see the .vscode/launch.json file.

Xdebug & PhpStorm

First, install the Chrome Xdebug helper. After installed, right click on the Chrome icon for it and go to Options. Under IDE Key, select PhpStorm from the list to set the IDE Key to "PHPSTORM", then click Save.
Next, enable Xdebug debugging in the PHP container by running: bin/xdebug enable.
Then, open PhpStorm > Preferences > PHP and configure:
- CLI Interpreter
  - Create a new interpreter from the From Docker, Vagrant, VM... list.
  - Select the Docker Compose option.
  - For Server, select Docker. If you don't have Docker set up as a server, create one and name it Docker.
  - For Configuration files, add both the docker-compose.yml and docker-compose.dev.yml files from your project directory.
  - For Service, select phpfpm, then click OK.
  - Name this CLI Interpreter phpfpm, then click OK again.
- Path mappings
  - There is no need to define a path mapping in this area.
Open PhpStorm > Preferences > PHP > Debug and ensure Debug Port is set to 9000,9003.
Open PhpStorm > Preferences > PHP > Servers and create a new server:
- For the Name, set this to the value of your domain name (ex. magento.test).
- For the Host, set this to the value of your domain name (ex. magento.test).
- Keep port set to 80.
- Check the "Use path mappings" box and map src to the absolute path of /var/www/html.
Go to Run > Edit Configurations and create a new PHP Remote Debug configuration.
- Set the Name to the name of your domain (ex. magento.test).
- Check the Filter debug connection by IDE key checkbox, select the Server you just setup.
- For IDE key, enter PHPSTORM. This value should match the IDE Key value set by the Chrome Xdebug Helper.
- Click OK to finish setting up the remote debugger in PHPStorm.
Open up pub/index.php and set a breakpoint near the end of the file.
- Start the debugger with Run > Debug 'magento.test', then open up a web browser.
- Ensure the Chrome Xdebug helper is enabled by clicking on it and selecting Debug. The icon should turn bright green.
- Navigate to your Magento store URL, and Xdebug should now trigger the debugger within PhpStorm at the toggled breakpoint.

SSH

Since version 40.0.0, this project supports connecting to Docker with SSH/SFTP. This means that if you solely use either PhpStorm or VSCode, you no longer need to selectively mount host volumes in order to gain bi-directional sync capabilities from host to container. This will enable full speed in the native filesystem, as all files will be stored directly in the appdata container volume, rather than being synced from the host. This is especially useful if you'd like to sync larger directories such as generated, pub & vendor.

Copy docker-compose.dev-ssh.yml to docker-compose.dev.yml before installing Magento to take advantage of this setup. Then, create an SFTP connection at Preferences -> Build, Execution, Deployment -> Deployment. Connect to localhost and use app for the username & password. You can set additional options for working with Magento in PhpStorm at Preferences -> Build, Execution, Deployment -> Deployment -> Options.

Note that you must use your IDE's SSH/SFTP functionality, otherwise changes will not be synced. To re-sync your host environment at any time, run:

bin/copyfromcontainer --all

Linux

Running Docker on Linux should be pretty straight-forward. Note that you need to run some post install commands as well as installing Docker Compose before continuing. These steps are taken care of automatically with Docker Desktop, but not on Linux.

Copy docker-compose.dev-linux.yml to docker-compose.dev.yml before installing Magento to take advantage of this setup.

The host.docker.internal hostname

The host.docker.internal hostname is used on Docker for Mac/Windows to reference the Docker daemon. On Linux, this hostname does not exist.

This hostname is hard-coded in the php.ini file. To make this hostname resolve, add "host.docker.internal:172.17.0.1" to the app.extra_hosts parameter of docker-compose.yml, replacing 172.17.0.1 with the result of:

docker run --rm alpine ip route | awk 'NR==1 {print $3}'

You must also create a new entry in your /etc/hosts file using the same IP:

172.17.0.1 host.docker.internal

Extra settings

To enable Xdebug on Linux, you may also need to open port 9003 on the firewall by running:

sudo iptables -A INPUT -p tcp --dport 9003 -j ACCEPT

You may also have to increase a virtual memory map count on the host system which is required by Elasticsearch.

Add the following line to the /etc/sysctl.conf file on your host:

vm.max_map_count=262144

Blackfire.io

These docker images have built-in support for Blackfire.io. To use it, first register your server ID and token with the Blackfire agent:

bin/root blackfire-agent --register --server-id={YOUR_SERVER_ID} --server-token={YOUR_SERVER_TOKEN}

Next, open up the bin/start helper script and uncomment the line:

#bin/root /etc/init.d/blackfire-agent start

Finally, restart the containers with bin/restart. After doing so, everything is now configured and you can use a browser extension to profile your Magento store with Blackfire.

MFTF

To work with MFTF you will need to first enable the selenium image in the docker-compose.dev.yml file. Then, you will need to run the following.

Run mftf build process bin/mftf build:project. This should build the basic setup for mftf in your project.
Update the extra_host values to match your Magento URL and IP in docker-compose.dev.yml.
Update the values in src/dev/tests/acceptance/.env, including adding the new line SELENIUM_HOST=selenium to define the host Codeception should connect to.
Run a sample test bin/mftf run:test AdminLoginSuccessfulTest.
Update your nginx.conf file to allow access to the dev section with the following, before the final deny all section:

location ~* ^/dev/tests/acceptance/utils($|/) {
    root $MAGE_ROOT;
    location ~ ^/dev/tests/acceptance/utils/command.php {
        fastcgi_pass   fastcgi_backend;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

For debugging, you can connect to the selenium image using a VCN client.

Connect with the VCN option and 127.0.0.1:5900, (default password: secret)
Run bin/mftf doctor to validate all sections are setup correctly.

Find more info here about mftf configuration.
