********************************

Docker on Linux: Xdebug for Atom
|
|
********************************
|
|
|
|
Docker on Linux allows Xdebug to automatically connect back to the host system without the need
|
|
of an explicit IP address.

Prerequisites
|
|
=============
|
|
|
|
Ensure you know how to customize ``php.ini`` values for the Devilbox and have a rough understanding
|
|
about common Xdebug options.
|
|
|
|
.. seealso::
|
|
* :ref:`php_ini`
|
|
* :ref:`configure_php_xdebug_options`
|
|
|
|
|
|
Assumption
|
|
==========
|
|
|
|
For the sake of this example, we will assume the following settings and file system paths:
|
|
|
|
+------------------------------+------------------------------------------+
|
|
| Directory | Path |
|
|
+==============================+==========================================+
|
|
| Devilbox git directory | ``/home/cytopia/repo/devilbox`` |
|
|
+------------------------------+------------------------------------------+
|
|
| :ref:`env_httpd_datadir` | ``./data/www`` |
|
|
+------------------------------+------------------------------------------+
|
|
| Resulting local project path | ``/home/cytopia/repo/devilbox/data/www`` |
|
|
+------------------------------+------------------------------------------+
|
|
| Selected PHP version | ``5.6`` |
|
|
+------------------------------+------------------------------------------+
|
|
|
|
The **Resulting local project path** is the path where all projects are stored locally on your
|
|
host operating system. No matter what this path is, the equivalent remote path (inside the Docker
|
|
container) is always ``/shared/httpd``.
|
|
|
|
.. important:: Remember this, when it comes to path mapping in your IDE/editor configuration.
|
|
|
|
|
|
Configuration
|
|
=============
|
|
|
|
Install php-debug for Atom
|
|
--------------------------
|
|
|
|
Ensure you have ``php-debug`` installed for Atom.
|
|
|
|
.. seealso:: |ext_lnk_xdebug_ide_atom_php_debug|
|
|
|
|
Configure Atom
|
|
--------------
|
|
|
|
You will need to configure the path mapping in ``config.cson`` (Atom configuration file) or via UI:
|
|
|
|
.. code-block:: js
|
|
:caption: config.cson
|
|
:emphasize-lines: 6
|
|
|
|
"php-debug":
|
|
{
|
|
ServerPort: 9000
|
|
PathMaps: [
|
|
"remotepath;localpath"
|
|
"/shared/httpd;/home/cytopia/repo/devilbox/data/www"
|
|
]
|
|
}
|
|
|
|
.. important::
|
|
Recall the path settings from the *Assumption* section and adjust if your configuration differs!
|
|
|
|
Configure php.ini
|
|
-----------------
|
|
|
|
.. note:: The following example show how to configure PHP Xdebug for PHP 5.6:
|
|
|
|
Create an ``xdebug.ini`` file (must end by ``.ini``):
|
|
|
|
.. code-block:: bash
|
|
|
|
# Navigate to the Devilbox git directory
|
|
host> cd path/to/devilbox
|
|
|
|
# Navigate to PHP 5.6 ini configuration directory
|
|
host> cd cfg/php-ini-5.6/
|
|
|
|
# Create and open debug.ini file
|
|
host> vi xdebug.ini
|
|
|
|
Copy/paste all of the following lines into the above created ``xdebug.ini`` file:
|
|
|
|
.. code-block:: ini
|
|
:caption: xdebug.ini
|
|
:emphasize-lines: 7,10
|
|
|
|
; Defaults
|
|
xdebug.default_enable=1
|
|
xdebug.remote_enable=1
|
|
xdebug.remote_port=9000
|
|
|
|
; The Linux way
|
|
xdebug.remote_connect_back=1
|
|
|
|
; idekey value is specific to Atom
|
|
xdebug.idekey=xdebug.atom
|
|
|
|
; Optional: Set to true to always auto-start xdebug
|
|
xdebug.remote_autostart=false
|
|
|
|
.. note:: Host os and editor specific settings are highlighted in yellow and are worth googling to get a better understanding of the tools you use and to be more efficient at troubleshooting.
|
|
|
|
|
|
Restart the Devilbox
|
|
--------------------
|
|
|
|
Restarting the Devilbox is important in order for it to read the new PHP settings.
|
|
Note that the following example only starts up PHP, HTTPD and Bind.
|
|
|
|
.. code-block:: bash
|
|
|
|
# Navigate to the Devilbox git directory
|
|
host> cd path/to/devilbox
|
|
|
|
# Stop, remove stopped container and start
|
|
host> docker-compose stop
|
|
host> docker-compose rm
|
|
host> docker-compose up php httpd bind
|
|
|
|
|
|
