Websocket not connecting - Docker

Question

I have Laravel running in a Docker environment with the packages mysql,nginx and php-fpm. I use it as an API. I want to add the websocket, the server is started via php artisan websocket:serve using supervisor. I can't connect to the statistic laravel-websockets, I don't see any ping pong on console.

What am i doing wrong ?

broadcasting.php

   'pusher' => [
        'driver' => 'pusher',
        'key' => env('PUSHER_APP_KEY'),
        'secret' => env('PUSHER_APP_SECRET'),
        'app_id' => env('PUSHER_APP_ID'),
        'options' => [
            'cluster' => env('PUSHER_APP_CLUSTER'),
            'scheme' => 'http',
            'host' => '127.0.0.1',
            'port' => 6001
        ],
    ],

ngnix.conf

map $http_upgrade $type {
default "web";
websocket "ws";
 }

}

}

    ],

The containers

As far as I can see your websocket server is not in the same container as your php server, so when you try to connect to localhost it fails.

If you want to connect to a different container you should use the name of that container instead of localhost, in your case:

'pusher' => [
    'driver' => 'pusher',
    'key' => env('PUSHER_APP_KEY'),
    'secret' => env('PUSHER_APP_SECRET'),
    'app_id' => env('PUSHER_APP_ID'),
    'options' => [
        'cluster' => env('PUSHER_APP_CLUSTER'),
        'scheme' => 'http',
        'host' => 'php-fpm-service-V2', // Name of the php server
        'port' => 6001
    ],
],
