Docker Xdebug Php

Xdebug is an extension for debugging your PHP code. Magento Cloud Docker provides a separate container to handle Xdebug requests in the Docker environment. Use this container to enable Xdebug and debug PHP code in your Docker environment without affecting your.

Open bar service for wedding. On this post we are setting up a Docker Container for Centos 7 and PHP 7.3 with an installation of Xdebug.

The docker host IP (ie the IP of the laptop seen from Docker) is hard coded in the docker image. This IP should match with yours. The IP in your docker image can be found in the php.ini docker exec -it doku bash cat /usr/local/etc/php/php.ini grep -i xdebug.remotehost xdebug.remotehost=host.docker.internal.

If you compare this Dockerfile with our previous one for PHP 7.3 you will notice that we have included the php-devel package. This is required since we will be using pecl to install Xdebug, which will build, install and load it.
Additionally we will need to install the make package.

  • Note that we have specified host.docker.internal as the IP address of our host machine, instead of an actual IP address. That is a docker variable that will be translated into the IP address of the machine running the docker container.

Create the Docker Image and Container

Now we create the Docker Image.


Then we create the Docker Container.

Notice that we need to indicate the path of our local folder that will be served as the root of the Apache Web Server, which in this example is /path_to/my_website. Replace it with the location of your site's root folder.


After the Docker Container is created, you can go to the url http://localhost:4000 to open the local website.


To check Xdebug has been correctly installed and configured, open a terminal window into the Docker Container with the following command:

Phpstorm Docker Xdebug Path Mappings

Docker Xdebug Php

Then, on the terminal window inside the container, we will use the php -i instruction to get information about our PHP installation. We will also use the grep utility to display only the information relevant to Xdebug:
