Can't run php-xdebug in docker(WSL2)

[slps970093]

I tried to set up a PHP development environment in Docker in WSL 2 mode, and it does not work with Xdebug

Could you please supply more details of what you did, what you expected, the symptoms, and include a diagnostics id. Thank you.

I execute docker-compose
The yml format is as follows

version: '2.0'

services:
  buylive_redis:
    container_name: buylive_redis
    image: redis:5
    ports:
      - 6379:6379
    networks:
      - buylive_network
    volumes:
      - D:\dockerToolbox\share\php\buylive\docker_compose\dev\php74\redis.conf:/usr/local/etc/redis/redis.conf
    command: [ "redis-server", "/usr/local/etc/redis/redis.conf" ]
  buylive:
    build:
      context: images
      dockerfile: Dockerfile
    container_name: "buylive_dev_web"
    volumes:
      - D:\dockerToolbox\share\php\buylive\:/var/www/html
      - D:\dockerToolbox\share\php\buylive\docker_compose\dev\php74\php.ini:/usr/local/etc/php/php.ini
    ports:
      - 80:80
    depends_on:
      - buylive_db
      - buylive_redis
    networks:
      - buylive_network
  buylive_db:
    container_name: "buylive_dev_db"
    image: "mysql:5.7"
    ports:
      - 3306:3306
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: "my2276"
    networks:
      - buylive_network
networks:
  buylive_network:
    driver: bridge

i'm having the same issue. somehow xdebug never seems to pick up on the request from the browser.
I'm trying to follow this guide currently to see if it's any help: https://www.silverf0x00.com/setting-up-xdebug-for-phpstorm-on-windows-wsl2/ so far i'm not having much luck.

I've tried setting xdebug.remote_host= manually to the IP of my wsl2 instance, and i've tried host.docker.internal which doesn't seem to work either. dunno if it's port 9000 that isn't making it all the way through or what. will keep digging...

Update: made some progress using this guide:

• https://gcompagnon.github.io/wsl2/xdebug/vscode/php-fpm/2019/09/17/WSL2_php_VSCode_Xdebug.html
  and this troubleshooting reference
• https://riimu.net/2019/02/troubleshooting-xdebug-remote-debugging/

I ended up adding a portproxy from *:9009 to my WSL's IP:9009 in PowerShell (run as Admin)

PS C:\Windows\System32> netsh interface portproxy add v4tov4 listenport=9009 connectaddress=172.19.0.78 connectport=9009

PS C:\Windows\System32> netsh interface portproxy show all

Listen on ipv4:             Connect to ipv4:

Address         Port        Address         Port
--------------- ----------  --------------- ----------
*               9009        172.19.0.78     9009

now i'm finally getting output in my /var/log/xdebug.log "remote_log" file in my WSL2 Ubuntu > Docker Ubuntu container

my xdebug.ini:

xdebug.remote_enable=1
xdebug.remote_autostart=1
xdebug.remote_handler=dbgp
xdebug.remote_port=9009
xdebug.remote_host=172.20.0.1
xdebug.remote_log = /var/log/xdebug.log

my workspace launch.json:

{
	"folders": [
		{
			"path": "./"
		}
	],
	"settings": {},
	"launch": {
		"version": "0.2.0",
		"configurations": [
			{
				"log": true,
				"name": "Listen for XDebug",
				"type": "php",
				"request": "launch",
				"hostname": "0.0.0.0",
				"port": 9009,
				"pathMappings": {
					"/var/www/": "./src/"

			},
		]
	}
}
