PHPSTORM XDEBUG DOCKER HOW TO
PHPSTORM XDEBUG DOCKER INSTALL

These two settings allow PHPStorm and Xdebug to communicate. The 'remote_port' is the port that PHPStorm will be listening for incoming Xdebug connections. The 'remote host' is the private ip of your host machine (the one your PHPStorm is running).

XDEBUG_CONFIG - This variable allows to define some Xdebug configurations.

PHP_IDE_CONFIG - This variable defines the server configuration associated with the application.

We will define the following environment variables:

If you prefer in you can also add directly to the docker-compose file using the 'environment' section. We will use that file to add some required environment variables for Xdebug. The important bit is the 'env_file' instruction which tells Compose to load environment variables from a '.env' file, which is the standard way for Symfony 4 applications. Here is the relevant excerpt of the Dockerfile that installs Xdebug:Įnter fullscreen mode Exit fullscreen mode You can follow along with the Dockerfile included in the demo repository.

PHPSTORM XDEBUG DOCKER HOW TO

I wont enter in detail about how to Dockerize a Symfony application. The way to do this, will depend of your base image.

PHPSTORM XDEBUG DOCKER INSTALL

Of course, to be able to use Xdebug you must install it on your Docker container.

You can clone this repository as base to follow this gude as it contains a basic Symfony Flex application with all the Docker stuff explained in this article included.

I assume you have a basic Knowledge of Docker, PHP and XDebug.

Some things might work a little different in other Operating Systems.

This was tested on an Ubuntu 18.04 machine with PHPStorm 2018.1.4 and latest versions of Docker and Docker Compose.

It will guide you to step by step through the process of installing and configuring Xdebug and PHPStorm with a Dockerized Symfony 4 application. Thats why I decided to write this article. I couldn't find a single guide that have all the steps from start to finish. And in case of getting Xdebug to work, its not an easy task. Also some things that were very easy in a normal development environment running locally, like debugging your application from your IDE, now requires some extra configuration. There is an extra complexity of maintaining all the Docker stuff. Docker make it such much easier, faster and consistent.īut everything comes with a price.

I still remember being like the first 3 days when I joined my current company, configuring the project and all the related libraries and tools. These advantages are even greater when working on a team or enterprise context. Thanks to it, it is really easy for everyone to run a complex application with a single command, without having to worry about the inner details like dependencies. Docker has changed dramatically the way we develop applications.
