"""Context for specifying OpenStack clients versions and service types.
|
|
|
|
Some OpenStack services support several API versions. To recognize
|
|
the endpoints of each version, separate service types are provided in
|
|
Keystone service catalog.
|
|
|
|
Rally has the map of default service names - service types. But since
|
|
service type is an entity, which can be configured manually by admin(
|
|
via keystone api) without relation to service name, such map can be
|
|
insufficient.
|
|
|
|
Also, Keystone service catalog does not provide a map types to name
|
|
(this statement is true for keystone < 3.3 ).
|
|
|
|
This context was designed for not-default service types and not-default
|
|
API versions usage.
|
|
|
|
An example of specifying API version:
|
|
|
|
.. code-block:: json
|
|
|
|
# In this example we will launch NovaKeypair.create_and_list_keypairs
|
|
# scenario on 2.2 api version.

|
}
|
|
]
|
|
}
|
|
|
|
An example of specifying API version along with service type:
|
|
|
|
.. code-block:: json
|
|
|
|
# In this example we will launch CinderVolumes.create_and_attach_volume
|
|
# scenario on Cinder V2

"times": 5,

"concurrency": 1
|
|
},

}
|
|
}
|
|
}
|
|
}
|
|
]
|
|
}
|
|
|
|
Also, it possible to use service name as an identifier of service endpoint,
|
|
but an admin user is required (Keystone can return map of service
|
|
names - types, but such API is permitted only for admin). An example:
|
|
|
|
.. code-block:: json
|
|
|
|
# Similar to the previous example, but `service_name` argument is used
|
|
# instead of `service_type`
