Hola Maestros, the rancher2_cloud_credential for Openstack - you only specify password. Which username does that use?

Does it use an api key from a user?

Dont believe it does. You only specify password. However in the machine pools you specify the cloud_credential together with the machine_config. I guess it uses the user from that. its the only logic i can see, dont really understand why you need to enter a cloud credential when the machine_config contain both username and password for the infrastructure.
