Database Operations

class openstack.database.v1._proxy.Proxy(session, statsd_client=None, statsd_prefix=None, prometheus_counter=None, prometheus_histogram=None, influxdb_config=None, influxdb_client=None, *args, **kwargs)
create_database(instance, **attrs)

Create a new database from attributes

Parameters

  • instance – This can be either the ID of an instance or a Instance

  • attrs (dict) – Keyword arguments which will be used to create a Database, comprised of the properties on the Database class.

Returns

The results of server creation

Return type

Database

delete_database(database, instance=None, ignore_missing=True)

Delete a database

Parameters

  • database – The value can be either the ID of a database or a Database instance.

  • instance – This parameter needs to be specified when an ID is given as database. It can be either the ID of an instance or a Instance
