Intro

A basic Docker setup, with zero initial configuration, for a development environment using Docker, Nginx, PHP-FPM, Xdebug.

Quickstart

Place your code in the apps/default folder, then run docker-compose up and your app will be available on http://localhost, port 80.

Things to know:

The document root of the server is in the ./apps/default folder.
Configuration files are located in the ./config folder
Log files will be placed in the ./logs folder

Nginx

If you need to customize the Nginx configuration (and you most probably will), make sure that you include in your configuration the ./nginx/xdebug/remote.conf file. That sets the remote_host setting needed by Xdebug to be able to connect back to your IDE.

To add more hosts or edit existing ones, add/edit the files located in ./config/nginx/hosts.

Xdebug

The configuration file for Xdebug is located at ./config/php/xdebug.ini. By default, Xdebug is configured to use port 9000 and autostart is off. You can set it to on or you can use a browser extension such as Xdebug helper for Chrome to only enable debugging when necessary (for performance reasons).

xdebug.remote_connect_back is disabled and xdebug.remote_host is automatically set by Nginx to one of the special hostnames provided by Docker (docker.for.win.localhost or docker.for.mac.localhost) after sniffing the client's operating system. (see ./config/nginx/xdebug/remote.conf)

To see the debug log, un-comment the xdebug.remote_log setting in the config file.

Other

Sample debug configuration for VS Code (using the default settings):

{
	"version": "0.2.0",
	"configurations": [
		{
			"name": "Listen for XDebug",
			"type": "php",
			"request": "launch",
			"port": 9000,
			"pathMappings": {
				"/": "${workspaceFolder}/",
			}
		}
	]
}
