Docker configuration to run a Symfony app.
docker-compose up -d --build
docker-compose run php composer install
You can now visit http://localhost:8080 and you will see the default Symfony page.
Symfony commands:
docker-compose exec php bin/console
The official Nginx image is used with a slight addition for permissions.
The virtual host is defined in the app.conf file. This file is shared with the container
as defined in the docker-compose.yml file. I prefer to share the host like this instead of using COPY in the Dockerfile
as there is no need to build a new image if the host changes. A simple docker-compose up -d will take
the new host into account.
PHP-FPM 7.4 is installed with the following configuration:
- Necessary extensions for Symfony
- MySQL
- GD
- Composer
- PHPUnit
- Xdebug
Making Xdebug working with Docker is quite tricky as there is currently a limitation to Docker for Mac that prevents a container to make a request to the the host, which is exactly what we would like to do with Xdebug.
To make Xdebug debugging work, you will first need to run this command on the host:
sudo ifconfig lo0 alias 10.200.10.1/24
This IP address is configured in the environment variables of the PHP container, in the docker-compose.yml file:
services:
php:
# ...
environment:
XDEBUG_REMOTE_HOST: 10.200.10.1
No extra configuration is needed in your IDE (tested on Sublime Text, Visual Studio Code and Atom), apart the usual.
