The Tricircle Admin API¶

This Admin API documentation describes the ways of interacting with the Tricircle service via HTTP protocol using Representational State Transfer(ReST).

API Versions¶

In order to bring new features to users over time, versioning is supported by the Tricircle. The latest version of the Tricircle is v1.0.

The Version APIs work the same as other APIs as they still require authentication.

GET

/

/{api_version}

List All Major versions

Show Details of Specific API Version

Service URLs¶

All API calls through the rest of this document require authentication with the OpenStack Identity service. They also require a base service url that can be got from the OpenStack Tricircle endpoint. This will be the root url that every call below will be added to build a full path.

For instance, if the Tricircle service url is http://127.0.0.1/tricircle/v1.0 then the full API call for /pods is http://127.0.0.1/tricircle/v1.0/pods.

As such, for the rest of this document we will leave out the root url where GET /pods really means GET {tricircle_service_url}/pods.

Pod¶

A pod represents a region in Keystone. When operating a pod, the Tricircle decides the correct endpoints to send request based on the region of the pod. Considering the architecture of the Tricircle, we have two kinds of pods: pod for central Neutron and pod for local Neutron.

GET

/pods

Retrieve Pod List

This fetches all the pods, including pod for central Neutron and pod(s) for local Neutron.

Normal Response Code: 200

Response

Pods contains a list of pod instances whose attributes are described in the following table.

Name	In	Type	Description
pod_id	body	string	pod_id is a uuid attribute of the pod object.
region_name	body	string	region_name is specified by user but must match the region name registered in Keystone.
az_name	body	string	When az_name is empty, it means this is a pod for central Neutron. If az_name is not empty, it means the pod will belong to this availability zone. Multiple pods with the same az_name means that these pods are under the same availability zone.
pod_az_name	body	string	pod_az_name is the az name used in the pod for local Neutron when creating network, router objects. It could be empty. If it’s empty, then no az parameter will be added to the request forwarded to the pod for local Neutron. If the pod_az_name is different from az_name, then the az parameter will be replaced with the pod_az_name when the request is forwarded to relevant pod for local Neutron.
dc_name	body	string	dc_name is the name of the data center where the pod is located.

Response Example

This is an example of response information for GET /pods.

pod_id	path	string	pod_id is a uuid attribute of the pod object.

Response

Here are two kinds of pods, including pod for central Neutron and pod for local Neutron. az_name is one of its attributes. A pod with empty az_name is for central Neutron, otherwise a pod with az_name specified is for local Neutron. All of its attributes are described in the following table.

pod_az_name	body	string	pod_az_name is the az name used in the pod for local Neutron when creating network, router objects. It could be empty. If it’s empty, then no az parameter will be added to the request forwarded to the pod for local Neutron. If the pod_az_name is different from az_name, then the az parameter will be replaced with the pod_az_name when the request is forwarded to relevant pod for local Neutron.

Normal Response Code: 200

Request

Name	In	Type	Description
pod_id	path	string	pod_id is a uuid attribute of the pod object.

Response

There is no response. But we can list all the pods to verify whether the specific pod has been deleted or not.

Resource Routing¶

The Tricircle is responsible for resource(for example, network, subnet, port, router, etc) creation both in local Neutron and central Neutron.

In order to dispatch resource operation request to the proper local Neutron, we need a resource routing table, which maps a resource from the central Neutron to local Neutron where it’s located.

When user issues a resource update, query or delete request, central Neutron will capture this request and extract resource id from the request, then dispatch the request to target local Neutron on the basis of the routing table.

GET

/routings

Retrieve All Resource Routings

This fetches all the resource routing entries by default, but we can apply filter(s) on the returned values to only show the specific routing entries. Accordingly the filtering condition(s) will be added to the tail of the service url separated by question mark. For example, the default service url is GET /routings, when filtering is applied, the service url becomes GET /routings?attribute=attribute_value. One or multiple conditions are supported.

Normal Response Code: 200

Response

The resource routing set contains a list of resource routing entries whose attributes are described in the following table.

Name	In	Type	Description
id	body	biginteger	id is the unique identification of the resource routing.
top_id	body	string	top_id denotes the resource id on central Neutron.
bottom_id	body	string	bottom_id denotes the resource id on local Neutron.
pod_id	body	string	pod_id is the uuid of one pod(i.e., one region).
project_id	body	string	project_id is the uuid of a project object in KeyStone. “Tenant” is an old term for a project in Keystone. Starting in API version 3, “project” is the preferred term. They are identical in the context.
resource_type	body	string	resource_type denotes one of the available resource types, including network, subnet, port, router and security_group.
created_at	body	timestamp	created time of the resource routing.
updated_at	body	timestamp	updated time of the resource routing.

Response Example

DELETE

/routings/{id}

Delete a Resource Routing

This deletes a resource routing entry. But deleting an existing routing entry created by Tricircle itself may cause problem: Central Neutron may make wrong judgement on whether the resource exists or not without this routing entry. Moreover, related request can’t be forwarded to the proper local Neutron either.

Normal Response Code: 200

Request

Response

There is no response. But we can list all the resource routing entries to verify whether the specific routing entry has been deleted or not.

PUT

/routings/{id}

Update a Resource Routing

This updates an existing resource routing entry. But updating an existing routing entry created by Tricircle itself may cause problem: Central Neutron may make wrong judgement on whether the resource exists or not without this routing entry. Moreover, related request can’t be forwarded to the proper local Neutron either.

Normal Response Code: 200
