OpenStack kolla 多 region 部署配置

region one：

 cat /etc/kolla/globals.yml

 openstack_region_name: "RegionOne"
 multiple_regions_names:
     - "{{ openstack_region_name }}"
     - "RegionTwo"

 enable_keystone: "yes"

region two：（region_one_vip：regionOne的keystone IP）

 cat /etc/kolla/globals.yml

 openstack_region_name: "RegionTwo"

 kolla_internal_fqdn_r1: region_one_vip
 keystone_admin_url: "{{ admin_protocol }}://{{ kolla_internal_fqdn_r1 }}:{{ keystone_admin_port }}"
 keystone_internal_url: "{{ internal_protocol }}://{{ kolla_internal_fqdn_r1 }}:{{ keystone_public_port }}"

 openstack_auth:
     auth_url: "{{ admin_protocol }}://{{ kolla_internal_fqdn_r1 }}:{{ keystone_admin_port }}"
     username: "admin"
     password: "{{ keystone_admin_password }}"
     project_name: "admin"
     domain_name: "default"

 enable_keystone: "no"

region two：

 [root@controller ~]# cat /etc/kolla/config/global.conf
 [keystone_authtoken]
 auth_uri = {{ keystone_internal_url }}
 auth_url = {{ keystone_admin_url }}

 [root@controller ~]# cat /etc/kolla/config/mistral.conf
 [keystone_authtoken]
 auth_uri = {{ keystone_internal_url }}/v3
 auth_url = {{ keystone_admin_url }}/v3
 [openstack_actions]
 default_region = RegionTwo  

 [root@controller ~]# cat /etc/kolla/config/heat.conf
 [DEFAULT]
 region_name_for_services = RegionTwo
 [trustee]
 auth_uri = {{ keystone_internal_url }}
 auth_url = {{ keystone_internal_url }}
 [ec2authtoken]
 auth_uri = {{ keystone_internal_url }}
 [clients_keystone]
 auth_uri = {{ keystone_internal_url }}

 [root@controller ~]# cat /etc/kolla/config/nova.conf
 [placement]
 auth_url = {{ keystone_admin_url }}

两个region节点都要执行kolla-ansible deploy
