Block Storage API

For details on how to use block_storage, see Using OpenStack Block Storage

The BlockStorage Class

The block_storage high-level interface is available through the block_storage member of a Connection object. The block_storage member will only be added if the service is detected.

Volume Operations

class openstack.block_storage.v2._proxy.Proxy(session, statsd_client=None, statsd_prefix=None, prometheus_counter=None, prometheus_histogram=None, influxdb_config=None, influxdb_client=None, *args, **kwargs)

get_volume(volume)

Get a single volume

Parameters

volume – The value can be the ID of a volume or a Volume instance.

Returns

One Volume

Raises

ResourceNotFound when no resource can be found.

volumes(details=True, **query)

Retrieve a generator of volumes

Parameters

• details (bool) – When set to False no extended attributes will be returned. The default, True, will cause objects with additional attributes to be returned.

• query (kwargs) –

  Optional query parameters to be sent to limit the volumes being returned. Available parameters include:

  • name: Name of the volume as a string.

  • all_projects: Whether return the volumes in all projects

  • status: Value of the status of the volume so that you can filter

    on “available” for example.

Returns

A generator of volume objects.

create_volume(**attrs)

Create a new volume from attributes

Parameters

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

Returns

The results of volume creation

Return type

Volume

delete_volume(volume, ignore_missing=True)

Delete a volume

Parameters

• volume – The value can be either the ID of a volume or a Volume instance.

• ignore_missing (bool) – When set to False ResourceNotFound will be raised when the volume does not exist. When set to True, no exception will be set when attempting to delete a nonexistent volume.

Returns

None

Backup Operations

class openstack.block_storage.v2._proxy.Proxy(session, statsd_client=None, statsd_prefix=None, prometheus_counter=None, prometheus_histogram=None, influxdb_config=None, influxdb_client=None, *args, **kwargs)

backups(details=True, **query)

Retrieve a generator of backups

Parameters

• details (bool) – When set to False no additional details will be returned. The default, True, will cause objects with additional attributes to be returned.

• query (dict) –

  Optional query parameters to be sent to limit the resources being returned:

  • offset: pagination marker

  • limit: pagination limit

  • sort_key: Sorts by an attribute. A valid value is

    name, status, container_format, disk_format, size, id, created_at, or updated_at. Default is created_at. The API uses the natural sorting direction of the sort_key attribute value.

  • sort_dir: Sorts by one or more sets of attribute and sort

    direction combinations. If you omit the sort direction in a set, default is desc.

Returns

A generator of backup objects.
