title: Laradock: Laravel queue worker can't connect to RabbitMQ
body: <p>I've set up a Laravel (5.6) application with RabbitMQ (3.7.6) using the latest Laradock and composer-installed
  <a href="https://github.com/vyuldashev/laravel-queue-rabbitmq" rel="nofollow noreferrer">https://github.com/vyuldashev/laravel-queue-rabbitmq</a> . When I start the Laravel message worker with <code>php artisan queue:work</code> I'm getting the following error</p>
  
  <pre><code>local.ERROR: AMQP error while attempting pop: stream_socket_client(): 
  unable to connect to tcp://127.0.0.1:5672 (Connection refused)  
  </code></pre>
  
  <p>However, I can connect to Rabbit using <code>telnet 127.0.0.1 5672</code> (the connection is closed after 10 seconds of inactivity). The listeners seem to be working correctly:</p>
  
  <pre><code>{listeners,[{clustering,25672,"::"},{amqp,5672,"::"},{http,15672,"::"}]}
  </code></pre>
  
  <p>I've also checked the RabbitMQ logs, but nothing shows up there. So I assume it's a problem on the client side but I'm not sure where to look.</p>
  
  <p>RabbitMQ settings in Laravel <code>.env</code></p>
  
  <pre><code>QUEUE_DRIVER=rabbitmq
  RABBITMQ_QUEUE=default
  RABBITMQ_DSN=amqp:
  </code></pre>
  
  <p>Laradock <code>.env</code></p>
  
  <pre><code>RABBITMQ_NODE_HOST_PORT=5672
  RABBITMQ_MANAGEMENT_HTTP_HOST_PORT=15672
  RABBITMQ_MANAGEMENT_HTTPS_HOST_PORT=15671
  RABBITMQ_DEFAULT_USER=guest
  RABBITMQ_DEFAULT_PASS=guest
  </code></pre>
  
  <p>Any ideas?</p>
