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

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

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

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.

MYSQL_DATABASE: Database name

environment:
	LANG: es_ES.UTF-8
	MYSQL_ROOT_PASSWORD: root
	MYSQL_DATABASE: nameproject
	MYSQL_USER: user
	MYSQL_PASSWORD: p@ssw0rd

Password: root

phpMyAdmin is a tool written in PHP with the intention of managing MySQL administration through web pages, using a web browser.

environment:
	- PMA_ARBITRARY=1

Password : admin

This table list which version of Xdebug is still supported.

https://xdebug.org/docs/compat

https://matthewsetter.com/setup-step-debugging-php-xdebug3-docker/

The configuration file for Xdebug is located at ./config/php/xdebug.ini.

#----------------------#
# Custom Xdebug config #
#----------------------#

zend_extension=xdebug

[xdebug]
xdebug.mode=develop,debug
xdebug.client_host=host.docker.internal
xdebug.start_with_request=yes
xdebug.client_port= 9003

By default, Xdebug is configured to use port 9003 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.

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

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Listen for XDebug",
      "type": "php",
      "request": "launch",
      "port": 9003,
      "pathMappings": {
        "/apps": "${workspaceFolder}/apps"
      }
    }
  ]
}

There are several versions of the Compose file format – 1, 2, 2.x, and 3.x. The table below is a quick look. For full details on what each version includes and how to upgrade, see About versions and upgrading.
