Ubuntu Linux+XDebug+VSCode

Hi, I was unable to make use of XDebug with VSCode in Linux, so after several hours of searching I finally founded what was the cause. The step by step solution is this:

1. As a precaution you need to open XDebug port in the firewall with: sudo ufw allow 9003
2. Then in VSCode you need to change the setting remote.localPortHost to allInterfaces
3. Then create a xdebug.ini file in docker/xdebug.ini with the following:

[XDebug]
zend_extension = xdebug.so
xdebug.mode = debug,profile,trace
xdebug.start_with_request = yes
xdebug.discover_client_host = 0
xdebug.client_port = 9003
xdebug.client_host=host.docker.internal

5. Then in VSCode set your launch.json with the following:

{
   "version": "0.2.0",
   "configurations": [
       {
           "name": "xDebug listen",
           "type": "php",
           "request": "launch",
           "port": 9003,
           "pathMappings": {
             "/srv/app/": "${workspaceFolder}/"
            }
        }
   ]
}

6. Finally your docker-compose.debug.yml should look like this:

# docker-compose.debug.yml
version: "3.4"

services:
  php:
    build:
      context: .
      target: symfony_php_debug
    volumes:
      # The "cached" option has no effect on Linux but improves performance on Mac
      - ./:/srv/app:rw,cached
      - ./docker/php/conf.d/symfony.dev.ini:/usr/local/etc/php/conf.d/symfony.ini
      - ./docker/xdebug.ini:/usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
    extra_hosts:
      # Ensure that host.docker.internal is correctly defined on Linux
      - host.docker.internal:host-gateway
  caddy:
    volumes:
      - ./docker/caddy/Caddyfile:/etc/caddy/Caddyfile:ro
      - ./public:/srv/app/public:ro

Thanks for that very well explained !

But I follow your solution and I have a 502 on https://localhost now, with PHP no pinging or log the DB healhcheck.
