Use Websocket with Google Compute Engine, HTTP(S) Load balancer

[maxime dhalluin]

Hi,

I'm trying to use Websocket with my app powered by GCE.

I'm using HTTPS load balancing and it's seems the load balancer does not like the https because it work on HTTP but not on HTTPS.

You can try my snake test game here (In simple HTTP) =>  http://www.writecontrol.fr/websocket/snake.html

There is an error if you test the same URL with HTTPS =>  https://www.writecontrol.fr/websocket/snake.html

I'm using ingress load balancer extensions/v1beta1

The SSL is based on a "secret tls" => https://cloud.google.com/endpoints/docs/openapi/enabling-ssl

So there is SSL between client and HTTPS load balancer, but not between load balancer and application instances

Logs into the application instance seems correct (No Exception) :

2017-12-20 20:07:04.986  INFO 5 --- [tp1875108260-24] monitoring                               : remoteAddr = 10.240.0.4, forwardedFor = 176.170.4.209, 35.190.37.177, request = /websocket/snake/info GET: 3 ms, 0 Ko

This is the log in GCE load balancing logging

 

 

 

 

 

 

 

 

}

 

 

 

}

 

 

 

 

 

 

 

 

}

 

}

 

 

Do you have any suggestions ?
