openstack.block_storage.v3.attachment

The Volume Attachment Class

The Volume Attachment class inherits from Resource.

class openstack.block_storage.v3.attachment.Attachment(_synchronized=False, connection=None, **attrs)

The base resource

Parameters:

  • _synchronized (bool) – This is not intended to be used directly. See new() and existing().

  • connection (openstack.connection.Connection) – Reference to the Connection being used. Defaults to None to allow Resource objects to be used without an active Connection, such as in unit tests. Use of self._connection in Resource code should protect itself with a check for None.

create(session, prepend_key=True, base_path=None, *, resource_request_key=None, resource_response_key=None, microversion=None, **params)

Create a remote resource based on this instance.

Parameters:

  • session (Adapter) – The session to use for making this request.

  • prepend_key – A boolean indicating whether the resource_key should be prepended in a resource creation request. Default to True.

  • base_path (str) – Base part of the URI for creating resources, if different from base_path.

  • resource_request_key (str) – Overrides the usage of self.resource_key when prepending a key to the request body. Ignored if prepend_key is false.

  • resource_response_key (str) – Overrides the usage of self.resource_key when processing response bodies. Ignored if prepend_key is false.

  • microversion (str) – API version to override the negotiated one.

  • params (dict) – Additional params to pass.

Returns:

This Resource instance.

Raises:

MethodNotSupported if Resource.allow_create is not set to True.

complete(session, *, microversion=None)

Mark the attachment as completed.

update([E, ]**F) → None.  Update D from dict/iterable E and F.

If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]
