Debugging Laravel with VSCode on Docker container using Xdebug as debugger

Question

I am trying to debug Laravel code on Visual Studio Code using Xdebug. I am using Docker container that works as server.

But I am getting this error when try to debug

You can use PHP Debug VS Code extension to connect with XDebug. PHP-FPM are run at port 9000 by default, so it's best to change the xdebug.remote_port settings to another port (e.g. 9001):

// launch.json

"version": "0.2.0",
"configurations": [
  {
    "name": "Listen for XDebug",
    "type": "php",
    "request": "launch",
    "pathMappings": { "/": "${workspaceRoot}/" },
    "port": 9001
  },
  {
    "name": "Launch currently open script",
    "type": "php",
    "request": "launch",
    "program": "${file}",
    "cwd": "${fileDirname}",
    "port": 9001
  }
]

If you are using Docker, Use these settings in your php.ini file :

//php.ini

[XDebug]
xdebug.remote_enable = 1
xdebug.remote_autostart = 1
xdebug.remote_host = host.docker.internal
xdebug.remote_port = 9001

As of Docker version 18.03, host.docker.internal points to host IP address on Mac / Windows. For Linux, you can use this workaround.

Once these settings are set, you are good to go.
