Code Issues Proposed changes

Move statless design from experiment to master branch

Browse Source 
The statless design was developed in the experiment branch, the experiment
shows advantage in removing the status synchronization, uuid mapping
compared to the stateful design, and also fully reduce the coupling with
OpenStack services like Nova, Cinder. The overhead query latency for
resources also acceptable. It's time to move the statless design to the
master branch

# Tricircle
(Attention Please, Stateless Design Proposal is being worked on the ["experiment"](https://github.com/openstack/tricircle/tree/experiment) branch).
(The original PoC source code, please switch to
["poc"](https://github.com/openstack/tricircle/tree/poc) tag, or
["stable/fortest"](https://github.com/openstack/tricircle/tree/stable/fortest)
branch)

Tricircle is an OpenStack project that aims to deal with multiple OpenStack
deployment across multiple data centers. It provides users a single management
view by having only one Tricircle instance on behalf of all the involved
OpenStack instances.
Tricircle is a openstack project that aims to deal with OpenStack deployment across multiple sites. It provides users a single management view by having only one OpenStack instance on behalf of all the involved ones. It essentially serves as a communication bus between the central OpenStack instance and the other OpenStack instances that are called upon.
Tricircle presents one big region to the end user in KeyStone. And each
OpenStack instance, which is called a pod, is a sub-region of Tricircle in
KeyStone, and not visible to end user directly.
Tricircle acts as OpenStack API gateway, can accept all OpenStack API calls
and forward the API calls to regarding OpenStack instance(pod), and deal with
cross pod networking automaticly.
The end user can see avaialbility zone (AZ in short) and use AZ to provision
VM, Volume, even Network through Tricircle.
Similar as AWS, one AZ can includes many pods, and a tenant's resources will
be bound to specific pods automaticly.

## Play with DevStack
Now stateless design can be played with DevStack.
- 1 Git clone DevStack.
- 2 Git clone Tricircle, or just download devstack/local.conf.sample
- 3 Copy devstack/local.conf.sample to DevStack folder and rename it to
local.conf, change password in the file if needed.
- 4 Run DevStack.
- 5 After DevStack successfully starts, check if services have been correctly
registered. Run "openstack endpoint list" and you should get similar output
as following:
```
+----------------------------------+-----------+--------------+----------------+
| ID | Region | Service Name | Service Type |
+----------------------------------+-----------+--------------+----------------+
| 230059e8533e4d389e034fd68257034b | RegionOne | glance | image |
| 25180a0a08cb41f69de52a7773452b28 | RegionOne | nova | compute |
| bd1ed1d6f0cc42398688a77bcc3bda91 | Pod1 | neutron | network |
| 673736f54ec147b79e97c395afe832f9 | RegionOne | ec2 | ec2 |
| fd7f188e2ba04ebd856d582828cdc50c | RegionOne | neutron | network |
| ffb56fd8b24a4a27bf6a707a7f78157f | RegionOne | keystone | identity |
| 88da40693bfa43b9b02e1478b1fa0bc6 | Pod1 | nova | compute |
| f35d64c2ddc44c16a4f9dfcd76e23d9f | RegionOne | nova_legacy | compute_legacy |
| 8759b2941fe7469e9651de3f6a123998 | RegionOne | tricircle | Cascading |
+----------------------------------+-----------+--------------+----------------+
```
"RegionOne" is the region you set in local.conf via REGION_NAME, whose default
value is "RegionOne", we use it as the region for top OpenStack(Tricircle);
"Pod1" is the region set via "POD_REGION_NAME", new configuration option
introduced by Tricircle, we use it as the bottom OpenStack.
- 6 Create pod instances for Tricircle and bottom OpenStack
```
curl -X POST http://127.0.0.1:19999/v1.0/pods -H "Content-Type: application/json" \
-H "X-Auth-Token: $token" -d '{"pod": {"pod_name": "RegionOne"}}'
curl -X POST http://127.0.0.1:19999/v1.0/pods -H "Content-Type: application/json" \
-H "X-Auth-Token: $token" -d '{"pod": {"pod_name": "Pod1", "az_name": "az1"}}'
```
Pay attention to "pod_name" parameter we specify when creating pod. Pod name
should exactly match the region name registered in Keystone since it is used
by Tricircle to route API request. In the above commands, we create pods named
"RegionOne" and "Pod1" for top OpenStack(Tricircle) and bottom OpenStack.
Tricircle API service will automatically create a aggregate when user creates
a bottom pod, so command "nova aggregate-list" will show the following result:
```
+----+----------+-------------------+
| Id | Name | Availability Zone |
+----+----------+-------------------+
| 1 | ag_Pod1 | az1 |
+----+----------+-------------------+
```
- 7 Create necessary resources to boot a virtual machine.
```
nova flavor-create test 1 1024 10 1
neutron net-create net1
neutron subnet-create net1 10.0.0.0/24
glance image-list
```
Note that flavor mapping has not been implemented yet so the created flavor is
just a database record and actually flavor in bottom OpenStack with the same id
will be used.
- 8 Boot a virtual machine.
```
nova boot --flavor 1 --image $image_id --nic net-id=$net_id --availability-zone az1 vm1
```
- 9 Create, list, show and delete volume.
```
cinder --debug create --availability-zone=az1 1
cinder --debug list
cinder --debug show $volume_id
cinder --debug delete $volume_id
cinder --debug list
```

=======================
A site represents a region in Keystone. When operating a site, Tricircle
decides the correct endpoints to send request based on the region of the site.
A pod represents a region in Keystone. When operating a pod, Tricircle
decides the correct endpoints to send request based on the region of the pod.
Considering the 2-layers architecture of Tricircle, we also have 2 kinds of
sites: top site and bottom site. A site has the following attributes:
pods: top pod and bottom pod. A pod has the following attributes:
- site_id
- site_name
- az_id
- pod_id
- pod_name
- pod_az_name
- dc_name
- az_name
**site_id** is automatically generated when creating a site. **site_name** is
specified by user but **MUST** match the region name registered in Keystone.
When creating a bottom site, Tricircle automatically creates a host aggregate
and assigns the new availability zone id to **az_id**. Top site doesn't need a
host aggregate so **az_id** is left empty.
**pod_id** is automatically generated when creating a site.
**pod_name** is specified by user but **MUST** match the region name
registered in Keystone. When creating a bottom pod, Tricircle automatically
creates a host aggregate and assigns the new availability zone id to
**az_name**. When **az_name** is empty, that means this pod is top region,
no host aggregate will be generated. If **az_name** is not empty, that means
this pod will belong to this availability zone. Multiple pods with same
**az_name** means that these pods are under same availability zone.
**pod_az_name** is the az name in the bottom pod, it could be empty, if empty,
then no az parameter will be added to the request to the bottom pod. If the
**pod_az_name** is different than **az_name**, then the az parameter will be
replaced to the **pod_az_name** when the request is forwarded to regarding
bottom pod.
**dc_name** is the name of the data center where the pod is located.
