Docker image for Magento 2
For documentation, please refer to the Magento 1.x repo. These two Docker images follow the same instructions.
Note This docker image uses the Contributing developer profile to install Magento, so it has limitations. See more details here.
Please note: this Docker image is for development and testing only, not for production use. Setting up a Magento 2 production server requires more configurations. Please refer to official documentations.
Magento 2 installation types
Magento 2 has three different ways to install, for users, integrators and developers. This Docker image uses integrator as the default installation type, so the Web Setup Wizard can be used. For each version, both integrator and developer installation types are available. The user installation type is not currently supported.
For example, Magento 2 version
2.2.2 has tag
2.2.2 is the same as
Below are some basic instructions.
The easiest way to start Magento 2 with MySQL is using Docker Compose. Just clone this repo and run following command in the root directory. The default
docker-compose.yml uses MySQL and phpMyAdmin.
$ docker-compose up -d
For admin username and password, please refer to the file
env. You can also update the file
env to update those configurations. Below are the default configurations.
MYSQL_HOST=db MYSQL_ROOT_PASSWORD=myrootpassword MYSQL_USER=magento MYSQL_PASSWORD=magento MYSQL_DATABASE=magento MAGENTO_LANGUAGE=en_GB MAGENTO_TIMEZONE=Pacific/Auckland MAGENTO_DEFAULT_CURRENCY=NZD MAGENTO_URL=http://local.magento MAGENTO_BACKEND_FRONTNAME=admin MAGENTO_USE_SECURE=0 MAGENTO_BASE_URL_SECURE=0 MAGENTO_USE_SECURE_ADMIN=0 MAGENTO_ADMIN_FIRSTNAME=Admin MAGENTO_ADMIN_LASTNAME=MyStore MAGENTO_ADMIN_EMAILemail@example.com MAGENTO_ADMIN_USERNAME=admin MAGENTO_ADMIN_PASSWORD=magentorocks1
For example, if you want to change the default currency, just update the variable
You can find all available options in the official setup guide. If you need more options, fork this repo and add them in
Please see the following video for a quick demo.
After starting the container, you'll see the setup page of Magento 2. You can use the script
install-magento to quickly install Magento 2. The installation script uses the variables in the
$ docker exec -it <container_name> install-magento
$ docker exec -it <container_name> install-sampledata
Please note: Sample data for Magento 2.2.2 doesn't work at the moment, see this issue.
docker-compose.yml uses MySQL as the database and starts phpMyAdmin. The default URL for phpMyAdmin is
http://localhost:8580. Use MySQL username and password to log in.
Where is the database?
Magento 2 cannot run with a database. This image is for Magento 2 only. It doesn't contain MySQL server. MySQL server should be started in another container and linked with Magento 2 container. It's recommended to use Docker Compose to start both containers. You can also use Kubernetes or other tools.
Why accessing http://local.magento?
For development and testing in the local environment, using
localhost as Magento 2 URL has some issues. The default
env file use
http://local.magento as the value of
MAGENTO_URL. You need to edit your
hosts file to add the mapping from
localhost. You can use any domain names as long as it looks like a real domain, not
localhost doesn't work, try using
How to update Magento 2 installation configurations?
Depends on how the container is used,
- When using the GUI setup page of Magento 2, update configurations in the UI.
- When using the script, update configurations in the
- When starting Magento 2 as a standalone container, use
-eto pass environment variables.
Why getting access denied error after changing the default DB password?
If you change the default DB password in
env file and get the access denied error when installing Magento 2, see this issue comment.
Develop and test using this Docker image
As I mentioned before, this Docker image is primarily used for development and testing. Depends on the tasks you are trying to do, there are different ways to use this Docker image.
Extensions and themes
You can keep the extensions and themes directories on your local host machine, and use Docker Compose volumes to install the extensions and themes. For example, if you have a theme in the directory
/dev/mytheme, you can install it by specifying it in the
docker-composer.yml file. Then you can see the theme in Magento admin UI.
version: '3.0' services: web: image: alexcheng/magento2 ports: - "80:80" links: - db env_file: - env volumes: - /dev/mytheme:/var/www/html/app/design/frontend/mytheme/default db: image: mysql:5.6.23 volumes: - db-data:/var/lib/mysql/data env_file: - env phpmyadmin: image: phpmyadmin/phpmyadmin ports: - "8580:80" links: - db volumes: db-data:
Modify Magento core files
If you want to modify Magento core files, you cannot modify them directly in the container. Those changes will be lost. It's also not recommended to update Magento core files directly, which makes upgrading Magento a painful process. Actually, Docker makes the process much easier if you absolutely need to modify some core files. You can use volumes to overwrite files.
For example, if you want to overwrite the file
app/code/Magento/Catalog/Block/Product/Price.php, you can copy the content to a new file in your local directory
/dev/mycode/magento_2_2 and make the changes, then use
volumes to overwrite it.
volumes: - /dev/mycode/magento_2_2/app/code/Magento/Catalog/Block/Product/Price.php:/var/www/html/app/code/Magento/Catalog/Block/Product/Price.php
By using Docker, we can make sure that all your changes to Magento core files are kept in one place and tracked in source code repository. These changes are also correctly aligned with different Magento versions.
When deploying those changes to production servers, we can simply copy all files in the
/dev/mycode/magento_2_2 directory to Magento installation directory and overwrite existing files.
Test Magento compatibilities
This Docker images has different tags for corresponding Magento versions, e.g.
2.2.2. You can switch to different Magento versions very easily when testing extensions and themes.
