How do get ILPIP (PIP) from within a Node.JS application running ona VM in Azure? - node.js

Question

I need to get the DNS name (ILPIP DNS name) in a Node.JS application (an IoT gateway) that is running on a VM in Azure.
Background details.
I need this so the application can inform the web frontend where to open the socket.io connection to when the web based client wish to communicate with the IoT gateway.
I have been looking in Microsofts Azure modules for Node.JS but I haven't found anything that gives the ILPIP (assigned dns name)

You can try to use RoleEnvironment.getCurrentRoleInstance() function in Azure SDK for Node.js, run the following code snippet in a classic VM:
var azure = require('azure');
azure.RoleEnvironment.getCurrentRoleInstance(function (error, instance) {
if (!error && instance['endpoints']) {
//You can get information about "endpoint1" such as its address and port via
console.log(instance)
} else {
console.log(error);
}
});
You may get the following similar info of role instance:
{ id: 'WorkerRole1_IN_0',
roleName: 'WorkerRole1',
faultDomain: '0',
updateDomain: '0',
endpoints:
{ 'Microsoft.WindowsAzure.Plugins.RemoteAccess.Rdp':
{ name: 'Microsoft.WindowsAzure.Plugins.RemoteAccess.Rdp',
address: '100.104.92.19',
port: '3389',
publicPort: '0',
protocol: 'tcp',
roleInstanceId: 'WorkerRole1_IN_0' },
'Microsoft.WindowsAzure.Plugins.RemoteForwarder.RdpInput':
{ name: 'Microsoft.WindowsAzure.Plugins.RemoteForwarder.RdpInput',
address: '100.104.92.19',
port: '20000',
publicPort: '3389',
protocol: 'tcp',
roleInstanceId: 'WorkerRole1_IN_0' }
}
}
