docker_image = your-registry/your-repo/mysql
backup_docker_image = your-registry/your-repo/db-backup-mysql
* Setting username, uid, gid for each datastore
Currently, when a database container is running, it is owned by user:
database (UID: 1001) and group: database (GID: 1001).
In some cases, you may need to set the owner of files,
directories or container to adapt to your own datastore image.
To achieve this, you can configure the option
database_service_uname, database_service_uid, database_service_gid
in trove-guestagent.conf with following:
.. code-block:: ini
[<datastore_manage>]
database_service_uid = 1001
database_service_gid = 0
database_service_uname = postgres
Make Trove work with multiple versions for each datastore
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When Trove do a backup/restore actions, The Trove guest agent pulls container
