OpenStack Xena : How to use Trove2021/11/25 |
|
This is how to use Trove.
This example is based on the environment like follows.

| [1] | Download a VM image for Trove and add it to Glance. Also Create a Cinder volume type configured in [trove.conf]. |

| [2] | Add Datastore you'd like to use on the Node Trove API is running. (it's Network Node on this example) For example, add MariaDB, PostgreSQL on here. |

| [3] | Create a Database instance on a Node. For example, create a MariaDB Database instance with [admin] user on here. (by default policy, only [admin] user can create Trove instances) By the way, Database instance runs as a Dockder container inside a VM instance. |
