I note that there is a check whether the cluster is deployed into Azure Cloud .. see below.

I don't have a problem with that per se except that in a corporate environment I don't want to request a proxy whitelist exception with my CISO for an endpoint that we have no use for (http://www.azurespeed.com). Moreover, whilst this test will eventually timeout and the checks resume, it delays the process by whatever our default timeout is (120 secs I think) which is not ideal.

Could you make this check optional using something like this ...

parser.add_argument('--azurechk', action="store_true", help="whether to check if the cluster is deployed on azure cloud - defaults to true")
...
class HostDiscoveryHelpers:
    @staticmethod
    def get_cloud(host):
        if config.azurechk:
            ...

Kind Regards

Fraser.

            except requests.ConnectionError as e:
                logging.info("- unable to check cloud: {0}".format(e))
                return
        if "cloud" in metadata:
            return json.loads(metadata)["cloud"]
