Single pod installation with DevStack

Now the Tricircle can be played with all-in-one single pod DevStack. For the resource requirement to setup single pod DevStack, please refer to All-In-One Single Machine for installing DevStack in bare metal server or All-In-One Single VM for installing DevStack in virtual machine.

1 Install DevStack. Please refer to DevStack document on how to install DevStack into single VM or bare metal server.
2 In DevStack folder, create a file local.conf, and copy the content of https://github.com/openstack/tricircle/blob/master/devstack/local.conf.sample to local.conf, change password in the file if needed.
3 Run DevStack. In DevStack folder, run :
```
./stack.sh
```
4 After DevStack successfully starts, we need to create environment variables for the user (admin user as example in this document). In DevStack folder :
```
source openrc admin demo
```
5 Unset the region name environment variable, so that the command can be issued to specified region in following commands as needed :
```
unset OS_REGION_NAME
```

6 Check if services have been correctly registered. Run :

openstack --os-region-name=RegionOne endpoint list

you should get output looks like as following :

+----------------------------------+---------------+--------------+----------------+
| ID                               | Region        | Service Name | Service Type   |
+----------------------------------+---------------+--------------+----------------+
| 3944592550764e349d0e82dba19a8e64 | RegionOne     | cinder       | volume         |

| e0a5530abff749e1853a342b5747492e | CentralRegion | neutron      | network        |
+----------------------------------+---------------+--------------+----------------+

"CentralRegion" is the region you set in local.conf via CENTRAL_REGION_NAME, whose default value is "CentralRegion", we use it as the region for the central Neutron server and Tricircle Admin API(ID is 2ce48c73cca44e66a558ad69f1aa4436 in the above list). "RegionOne" is the normal OpenStack region which includes Nova, Cinder, Neutron.

7 Create pod instances for the Tricircle to manage the mapping between availability zone and OpenStack instances :
```
openstack multiregion networking pod create --region-name CentralRegion

openstack multiregion networking pod create --region-name RegionOne --availability-zone az1
```
Pay attention to "region_name" parameter we specify when creating pod. Pod name should exactly match the region name registered in Keystone. In the above commands, we create pods named "CentralRegion" and "RegionOne".

8 Create necessary resources in central Neutron server :

neutron --os-region-name=CentralRegion net-create --availability-zone-hint RegionOne net1
neutron --os-region-name=CentralRegion subnet-create net1 10.0.0.0/24

Please note that the net1 ID will be used in later step to boot VM.

9 Get image ID and flavor ID which will be used in VM booting :

glance --os-region-name=RegionOne image-list
nova --os-region-name=RegionOne flavor-list

10 Boot a virtual machine :

nova --os-region-name=RegionOne boot --flavor 1 --image $image_id --nic net-id=$net_id vm1

11 Verify the VM is connected to the net1 :
```
neutron --os-region-name=CentralRegion port-list
neutron --os-region-name=RegionOne port-list
nova --os-region-name=RegionOne list
```
The IP address of the VM could be found in local Neutron server and central Neutron server. The port has same uuid in local Neutron server and central Neutron Server.
