OpenStack Antelope : Trove 利用方法2023/03/29 |
|
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。

+-----------------------+ +-----------------------+ +-----------------------+
|
| [1] | Trove 用の VM イメージを公式サイトからダウンロードして Glance に登録します。 また、[trove.conf] で [cinder_volume_type] に設定したボリュームタイプを作成しておきます。 |

| [2] | 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 をデータストアとして登録します。 |

| [3] | Openstack システムを利用可能な任意のユーザーで認証して、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。 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。 |
