Neutron and some other services support number of service extensions. It would be good to make resources available based on the available service extensions.
ex. Make router, security-group, vpnaas, lbaas and other resources available based on the service extensions.
We can have 'has_extension' method on the client_plugins and then check it in 'is_service_available' of the Resource class.
ex.
os/neutron.py
---------------------
def has_extension(self, alias):
"""Check if specific extension is present."""
extensions = self.client().list_extensions().get('extensions')
return alias in [extension.get('alias') for extension in extensions]
engine/resource.py
-----------------------------
def is_service_available(cls, context):
......
for service_type in service_types:
endpoint_exists = client_plugin.does_endpoint_exist(
service_type=service_type,
service_name=cls.default_client_name)
req_extension = cls.required_service_extension
is_ext_available = (
not req_extension or client_plugin.has_extension(
req_extension))
if endpoint_exists and is_ext_available:
return True
router.py
-------------
required_service_extension = 'router'
