Hi,  
I’am trying to add an exernal REST service for testing purpose.

So first question : Is it possible to do that (calling an external rest service through this “external service” functionality instead of a direct call ?).

If yes, I’d like to add [openweathermap.org](http://openweathermap.org) free weather API.  
So I created a new stack, create the external service pointing to [openweathermap.org](http://openweathermap.org) (“hostname” mode)

Then I deployed a dummy service (in nodeJS) linked to openweathermap (with openweathermap alias).

So in my node code I try to call this external service like this :

```
var options = {
	method: 'GET',
	uri: 'http://openweathermap/data/2.5/weather?q=London&APPID={APIKEY}',
	headers: {
		"Content-type":"application/json"
	},
	json: true
};
...

```

but I have the following error :

```
{
name: "RequestError",
message: "Error: getaddrinfo EIO",
    cause: {
    code: "EIO",
    errno: "EIO",
    syscall: "getaddrinfo"
   },
}

```

I though I could use http://[alias\_name\_of\_external\_service]/xxx to call my external service from another container in stack.

Did I missed something?

Thank you for your help.
