- The restful API request will be routed to V1Controller from RootController for the version is 'v1.0':
- tricircle/tricircle/api/controllers/root.py
class RootController(object):
@expose()
def _lookup(self, version, *remainder):
if version == 'v1.0':
return V1Controller(), remainder
- In V1Controller, because the request is to create pod, so the request will be forwarded to PodsController: https://github.com/openstack/tricircle/blob/master/tricircle/api/controllers/root.py#L76
- The pod creation will be handled in the post function: https://github.com/openstack/tricircle/blob/master/tricircle/api/controllers/pod.py#L44~#L116
