Create a folder where you're going to keep your project
mkdir ~/test
Move inside of the folder
cd ~/test
Create a docker-compose.yml file in that folder with this content
version: "3.4"
services:
php:
image: webcu/symfony-installer:latest
restart: always
working_dir: /symfony
volumes:
- .:/symfony
command: tail -f /dev/null
ports:
- 8000:8000
environment:
XDEBUG_HOST_SETTING: host.docker.internal
PHP_IDE_CONFIG: "serverName=localhost"
Start the container
docker-compose up -d
Enter the container
docker-compose exec php bash
Create a new symfony project
symfony new test-project
If you want to avoid the warning message about your git identity, you can add your git config to your container adding this line to your docker-compose.yml file:
volumes:
...
# To add your git info to the container
- ~/.gitconfig:/etc/gitconfig
If you added the .gitconfig file after have created the container don't forget to recreate it ;)
# Exit your container
root@4725a7a23464:/symfony exit
# Recreate your container
docker-compose up -d --force-recreate
# Enter the new container
docker-compose exec php bash
# Create a new Symfony project
symfony new test-project
Start the Built-in web server of PHP
php -S 0.0.0.0:8000 -t test-project/public
php -S 0.0.0.0:8000
This allows that the web server can be accessed from outside the container.
-t test-project/public
Specifies the Document root of the server.
For more information about the Built-in web server of PHP check its documentation:

Now start writing your amazing application!
To simplify the process of the creation of the Dev Env for Symfony using Docker I created an image based on the Official PHP images that include some functionalities/extensions needed/recommended for Symfony 5. Those functionalities/extensions are:
You can find this image in Docker Hub. To use it you need to reference it in your docker-compose.yml file
services:
php:
image: webcu/symfony-installer
...
Use the official PHP images
There is a great team behind them to make those images the best possible.
Use the helper scripts: docker-php-ext-configure,docker-php-ext-install, docker-php-ext-enable. They are available in the Official PHP images to install more easily the PHP extensions.
To add a PHP development config add this line to your Dockerfile
...
RUN mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini"
...
Add your custom php ini config
Configure the php.ini options according to your needs.
Check this project if you don't want to deal directly with the installation of the php extensions:
