When creating a instance, is good to have the option of an instance-profile ARN so some policies con be applied ( for example as in https://aws.amazon.com/premiumsupport/knowledge-center/iam-policy-restrict-vpc/ )

the config file should have instance_profile_arn that is something similar to: "arn:aws:iam::ACCOUNTNUMBER:instance-profile/ROLENAME"

Reading nodemanager's code I noticed this bit on services/nodemanager/arvnodeman/config.py:

def new_cloud_client(self):
        module = importlib.import_module('arvnodeman.computenode.driver.' +
                                         self.get('Cloud', 'provider'))
        driver_class = module.ComputeNodeDriver.DEFAULT_DRIVER
        if self.has_option('Cloud', 'driver_class'):
            d = self.get('Cloud', 'driver_class').split('.')
            mod = '.'.join(d[:-1])
            cls = d[-1]
            driver_class = importlib.import_module(mod).__dict__[cls]
        auth_kwargs = self.get_section('Cloud Credentials')
        if 'timeout' in auth_kwargs:
            auth_kwargs['timeout'] = int(auth_kwargs['timeout'])
        return module.ComputeNodeDriver(auth_kwargs,
                                        self.get_section('Cloud List'),
                                        self.get_section('Cloud Create'),

It seems that simply adding the following at the [Cloud Create] config file section, will do the trick:

ex_iamprofile = arn:aws:iam::ACCOUNTNUMBER:instance-profile/ROLENAME
