OpenStack Victoria : Trove 利用方法2020/11/20 |
|
OpenStack Database Service（Trove）の利用方法です。
当例では以下のような環境を例に Trove をインストールしています。

| [3] | Trove API が稼働するノード (当例では Network ノード) で、使用したいデータストアを登録しておきます。 当例では、MariaDB, MySQL, PostgreSQL をデータストアとして登録します。 |

| [4] | 任意のノードで、データベースインスタンスを作成します。 例として、[admin] ユーザーで MariaDB データベースインスタンスを作成します。 (デフォルトポリシーでは [admin] ユーザーのみがインスタンス作成可) ちなみに、データベースインスタンスは VM イメージ上で Docker コンテナーとして起動します。 |
