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(*args, **kwargs)
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
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 Volume objects will be returned. The default, True, will cause VolumeDetail objects 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.

Backup Operations

class openstack.block_storage.v2._proxy.Proxy(*args, **kwargs)
create_backup(**attrs)

Create a new Backup from attributes with native API

Parameters:attrs (dict) – Keyword arguments which will be used to create a Backup comprised of the properties on the Backup class.
Returns:The results of Backup creation
Return type:Backup
delete_backup(backup, ignore_missing=True)

Delete a CloudBackup

Parameters:
  • backup – The value can be the ID of a backup or a Backup instance
  • ignore_missing (bool) – When set to False ResourceNotFound will be raised when the zone does not exist. When set to True, no exception will be set when attempting to delete a nonexistent zone.
Returns:

None
get_backup(backup)

Get a backup

Parameters:backup – The value can be the ID of a backup or a Backup instance.
Returns:Backup instance
Return type:Backup
backups(details=True, **query)

Retrieve a generator of backups

Parameters:
  • details (bool) – When set to False Backup objects will be returned. The default, True, will cause BackupDetail objects 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.
restore_backup(backup, volume_id, name)

Restore a Backup to volume

Parameters:
  • backup – The value can be the ID of a backup or a Backup instance
  • volume_id – The ID of the volume to restore the backup to.
  • name – The name for new volume creation to restore.
Returns:

Updated backup instance
Return type:

Backup

Type Operations

class openstack.block_storage.v2._proxy.Proxy(*args, **kwargs)

Return type:Type
delete_type(type, ignore_missing=True)

Delete a type

Parameters:
  • type – The value can be either the ID of a type or a Type instance.
