Bug 1009271

Feature enabled in https://github.com/openshift/origin-server/pull/3677

For testing you require a websocket enabled server and client...

    Add dependency to package.json:
    :
    .
      "dependencies": {
        "ws" : ">0.4.30"
      },
     
     
    Replace server.js to support web sockets:
     
    var host = process.env.OPENSHIFT_NODEJS_IP;
    var port = process.env.OPENSHIFT_NODEJS_PORT || 8080;
     
    var WebSocketServer = require('ws').Server,
        wss = new WebSocketServer({host: host, port: port});
        wss.on('connection', function(ws) {
          ws.on('message', function(message) {
            console.log('received: %s', message);
          });
          ws.send('something');
        });
     
     
    For a client:
    wscat -c ws://node001-honcenet.dev.rhcloud.com:8000/ -p 8

Every message you type, should be logged in /var/lib/openshift/<uuid>/nodejs/logs/node.log.

Merged onto master by https://github.com/openshift/origin-server/pull/3688

It's fixed, verified on devenv_3817, please refer to the following results:

1. Create a nodejs app
rhc app create nod1 nodejs-0.6
2. Replace server.js to support web sockets:
     
    var host = process.env.OPENSHIFT_NODEJS_IP;
    var port = process.env.OPENSHIFT_NODEJS_PORT || 8080;
     
    var WebSocketServer = require('ws').Server,
        wss = new WebSocketServer({host: host, port: port});
        wss.on('connection', function(ws) {
          ws.on('message', function(message) {
            console.log('received: %s', message);
          });
          ws.send('something');
        });
3. Add dependency to package.json:
    :
    .
      "dependencies": {
        "ws" : ">0.4.30"
      },
4. Push the changes
5. SSH into instance and idle this app
oo-admin-ctl-gears idlegear 52415129b723cc8c72000039
6. Access this app via websocket
wscat -c wss://nod1-cdm.dev.rhcloud.com:8443/ -p 8
or
wscat -c ws://nod1-cdm.dev.rhcloud.com:8000/ -p 8
7. Check the state of this app
# rhc app show -a nod1 --state
Cartridge nodejs-0.6 is started
