user in cloudmesh is as far as i remember not the username of the cloud, but the user on the local systems, so it coudl ebused in a multiuser environment. I forgot what the name is for the login
but maybe as multiple people developed some of them forgot and an inconsitence was introduced.

CloudmeshDatabase.refresh causes the username field (and perhaps others) to be overwritten. I noticed this when trying to deploy hadoop to chameleon which uses cc instead of ubuntu as the user. The deployment autodetects the node usernames but deployment was failing due to incorrect username. I traced the error to the refresh() method by stepping through the code and monitoring the table.
The relevant code snipped is below.
# get provider for specific cloud provider = CloudProvider(name).provider elements = cls.find(category=name, kind=kind, output='dict') current_elements = {} if elements: for element in elements: current_elements[element["name"]] = element # pprint(current_elements) # if purge: # cls.clear(kind=kind, category=name) elements = provider.list(kind, name) for element in list(elements.values()): element["uuid"] = element['id'] element['type'] = 'string' element["category"] = name # element["user"] = user element["kind"] = kind element["provider"] = provider.cloud_type if current_elements is not None: for index in current_elements: current = current_elements[index] for attribute in ["username", "image", "flavor", "group"]: if attribute in current and current[attribute] is not None: element[attribute] = current[attribute] # print ("CCC", index, element["name"], element["flavor"]) cls.add(element) return True
