Question:
Access Fiware objectstorage from Ruby: how do I connect without using password

Description:
I have an ruby-on-rails app which should store and retrieve images from Fiware objectstorage (which is based on Openstack swift).
There is gem called ruby-openstack that semm to do everything I need.

It works when I hardcode my email and fiware-password. But this seem not to be the right thing to do. The connection method gives me two other options:

1. :auth_method - Type of authentication - 'password', 'key', 'rax-kskey' - defaults to 'password'"
2. :username - Your OpenStack username or public key, depending on auth_method. required
3. :api_key - Your OpenStack API key required (either private key or password, depending on auth_method)

Should I choose "key" or "rax-kskey", and where do I get these keys from?
Is the private key the same I use to log in via ssh?
Or has it something to do with the "app" I can create in the Fiware-Backend?
