OpenStack Mitaka (三鷹) : Heat 利用方法
2016/06/08
 
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。

                            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。
