Trying to move my development environment to run on minikube.

The page loads but my page uses websockets on the same port/protocol that the index.html is loaded with (https in this case), and the websockets do no seem to be working correctly.

Here is an example of the correct output when run through nginx / python on my local development box.

Notice how there is a GET every 5 seconds (that's a timer running on the page)

When running on Kubernetes, The page loads and the timer shows up as if the websocket has worked, however I show no logs where the websocket is having a GET or POST after the initial one.

The Ingress is setup as follows:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-service
  annotations:
    kubernetes.io/ingress.class: nginx
spec:
  rules:
    - http:
        paths:
          - path: /
            backend:
              serviceName: websitev2-cluster-ip-service
              servicePort: 8080

As mentioned before, the websocket does not reside on a different port and it is instanciated in javascript as:

namespace = '/socket';
var socket = io.connect(location.protocol + '//' + document.domain + ':' + location.port + namespace);

Are there any special requirements to get websockets to work? I do not believe i need a special route because the URI needs to be sent to the same location as everything else, and on the same port.

EDIT: MORE DETAILS

My website has a form, that when submitted, executes the following code:

    $('form#job').submit(function(event) {
        var nameValue = JSON.stringify($(event.target).serializeArray());
        console.log(nameValue)
        socket.emit('job_submit', {data: nameValue});
        return false;
    });

On the python side, I have my socket code, which should get hit once a user clicks the submit button.

@socketio.on('job_submit', namespace='/socket')
def job_submit(message):
    print('recieved job_submit message from client')
    # kick off subjob in celery task
    data = unstringify(message)
    print('data = {0}'.format(data))
    sessiondata = dict(session)
    print('sessiondata = {}'.format(sessiondata))
    subjobstart.delay(sessiondata, request.sid, data)

In my logs I am not receiving any "recieved job_submit message from client" messages when the submit button is clicked, which means the javascript is trying to send a websocket emit to the python server, but the message is never getting there.

Emits from python to the client page are working as the time is getting updated on the site.
