1.What is the problem? Devstack plugin only supports the first region installation, for the second region installation with Tricircle local plugin, need to install the tricircle package manually (please refer to the multi-pod-installation-devstack.rst in doc/source). 2.What is the solution to the problem? If we want to support multi-region gate/check test job (https://blueprints.launchpad.net/tricircle/+spec/multi-region-job-for-gate-and-check-test), the second region in the gate/check job can only be installed through devstack plugin and local.conf. So we have to improve the devstack plugin to support the second region installation. Tricircle AdminAPI and XJob shouldn't be started in the second region, there is no need to generate database schema for the second region too. only the plugin needs to be installed and configured in local Neutron. So TRICIRCLE_START_SERVICES is introduced in devstack local.conf. The TRICIRCLE_START_SERVICES variable needs to be enabled in the first region and disabled in the second one. At the same time, remove the variable Q_ENABLE_TRICIRCLE judgement and configuration, if the Tricircle DevStack plugin is enabled, that means the plugin itself will run by default. 3.What the features need to be implemented to the Tricircle to realize the solution? No new features. Change-Id: Ib66a22f9e4889d131e5e481e9dec98efca5ed6fe Signed-off-by: joehuang <joehuang@huawei.com>

# Sample DevStack local.conf.
|
|
#
|
|
# This sample file is intended to be used for your typical Tricircle DevStack
|
|
# multi-node environment. This file has the configuration values for DevStack
|
|
# to result in Central Neutron service and Tricircle Admin API service
|
|
# registered in CentralRegion, and local Neutron service and remaining
|
|
# services(e. g. Nova, Cinder, etc.) will be placed in RegionOne, but Keystone
|
|
# will be registered in RegionOne and is shared by services in all the
|
|
# regions.
|
|
#
|
|
# This file works with local.conf.node_2.sample to help you build a two-node
|
|
# three-region Tricircle environment(Central Region, RegionOne and RegionTwo).
|
|
#
|
|
# Some options need to be changed to adapt to your environment, see README.rst
|
|
# for detail.
