Move statless design from experiment to master branch
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 BP: https://blueprints.launchpad.net/tricircle/+spec/implement-stateless Change-Id: I51bbb60dc07da5b2e79f25e02209aa2eb72711ac Signed-off-by: Chaoyi Huang <joehuang@huawei.com>changes/93/267293/2

# 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)
|

|
||||
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 |
|
||||
+----------------------------------+-----------+--------------+----------------+
|
||||

||||
| 25180a0a08cb41f69de52a7773452b28 | RegionOne | nova | compute |
|

|
||||

|
||||

|
||||

|
||||
| 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
|
||||
```
