OpenStack Liberty : Heat 利用方法2015/11/19 |
|
OpenStack Orchestration Service（Heat）の利用方法です。
ここでは以下のような環境を例に設定しています。
|
+------------------+ | +------------------------+
| [ Control Node ] | | | [ Network Node ] |
| Keystone |10.0.0.30 | 10.0.0.50| DHCP,L3,L2 Agent |
| Glance |------------+------------| Metadata Agent |
| Nova API |eth0 | eth0| Heat API,API-CFN |
| Neutron Server | | | Heat Engine |
+------------------+ | +------------------------+
eth0|10.0.0.51
+--------------------+
| [ Compute Node ] |
| Nova Compute |
| L2 Agent |
+--------------------+
|
| [1] | 構築した Heat サービスとテンプレートを利用してインスタンスをデプロイします。 作業は、どこでもよいですが、ここではコントロールノード上で行います。 |
