Attention

You can now run different PHP versions per project: Release v3.0.0-beta-0.1

3.2.3.1. Docker on Windows: Xdebug for Atom

Docker for Windows requires a well known IP address in order to connect to the host operating system.

Table of Contents

3.2.3.1.1. Prerequisites

3.2.3.1.1.1. General

Ensure you know how to customize php.ini values for the Devilbox and have a rough understanding about common Xdebug options.

3.2.3.1.1.2. Gather Host IP address

On Windows you will have to manually retrieve the IP address to which Xdebug should connect to via xdebug.remote_host.

When you have done no custom configuration in your Virtual Switch manager, Docker for Windows will use the Default Switch automatically.

  1. Open command line

  2. Enter ipconfig

  3. Look for the IP4 address in Default Switch (e.g.: 192.168.0.12)

    Important

    192.168.0.12 is meant as an example and will eventually differ on your system. Ensure you substitute it with the correct IP address.

3.2.3.1.2. 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
HOST_PATH_HTTPD_DATADIR ./data/www
Resulting local project path /home/cytopia/repo/devilbox/data/www
Selected PHP version 5.6
DockerNAT IP address 192.168.0.12
Virtual Switch IP address 192.168.0.12

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.

3.2.3.1.3. Configuration

3.2.3.1.3.1. Install php-debug for Atom

Ensure you have php-debug installed for Atom.

3.2.3.1.3.2. Configure Atom

You will need to configure the path mapping in config.cson (Atom configuration file) or via UI:

config.cson
"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!

Important

On Windows you have to use \\ as directory separators for the local path mapping. E.g.: C:\\Users\\projects.

3.2.3.1.3.3. 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):

# 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:

xdebug.ini
; Defaults
xdebug.default_enable=1
xdebug.remote_enable=1
xdebug.remote_port=9000

; The Windows way
xdebug.remote_connect_back=0
xdebug.remote_host=192.168.0.12

; idekey value is specific to Atom
xdebug.idekey=xdebug.atom

; Optional: Set to true to always auto-start xdebug
xdebug.remote_autostart=false

Important

Ensure you have retrieved the correct DockerNAT IP address as stated in the prerequisites section above!

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.

3.2.3.1.3.4. 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.

# 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
