Docker php+mysql+xdebug

Steps to create configuration:

  • Create docker-compose.yml
version: "2"

services:
    web:
        image: nginx:latest
        ports:
            - "80:80"
        volumes:
            - ./apps/default:/apps/default
            - ./logs/nginx:/logs/nginx
            - ./config/nginx/xdebug:/etc/nginx/xdebug
            - ./config/nginx/hosts:/etc/nginx/hosts
            - ./config/nginx/init.conf:/etc/nginx/conf.d/default.conf

    php:
        build:
            dockerfile: Dockerfile
            context: ./
        volumes:
            - ./apps/default:/apps/default
            - ./logs/xdebug:/logs/xdebug
            - ./config/php/custom.conf:/usr/local/etc/php-fpm.d/zz-custom.conf
            - ./config/php/xdebug.ini:/usr/local/etc/php/conf.d/zz-xdebug.ini
            - ./logs/php-fpm/:/tmp/xdebug_log
  • Create apps/default/index.php file:
<?php
$a=1;
$b=2;
$c=$a+$b;
echo($c);
  • Create configuration files:
-----------------------
config/php/custom.conf:

php_admin_flag[log_errors] = on
php_flag[display_errors] = off

----------------------
config/php/xdebug.ini:
; Custom Xdebug config

; xdebug.remote_log="/logs/xdebug/remote.log"
xdebug.remote_enable=1
xdebug.remote_autostart=0
xdebug.remote_connect_back=0
xdebug.remote_port=9000
; xdebug.remote_host=DYNAMICALLY SET IN config/nginx/xdebug/remote.conf

xdebug.profiler_enable_trigger=1
xdebug.profiler_enable=0
xdebug.profiler_output_dir="/logs/xdebug"

xdebug.var_display_max_children=-1
xdebug.var_display_max_data=-1
xdebug.var_display_max_depth=-1

-----------------------
config/nginx/init.conf:
include hosts/*.conf;

--------------------------------
config/nginx/hosts/default.conf:
server {
    listen 80;
    index index.php index.html;
    server_name localhost;
    error_log  /logs/nginx/error.log;
    access_log /logs/nginx/access.log;
    root /apps/default;


    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        include fastcgi_params;

        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;

        include xdebug/remote.conf;
    }
}

--------------------------------
config/nginx/xdebug/remote.conf:
set $xdebug_remote_host 'xdebug.remote_host=docker.for.mac.localhost';

if ($http_user_agent ~* 'windows') {
        set $xdebug_remote_host 'xdebug.remote_host=docker.for.win.localhost';
}

fastcgi_param PHP_VALUE $xdebug_remote_host;

Use Netbeans to create new php project with sources from apps/default directory. Set breakpoint to any string within code and run project in debug mode.

Done.
