openstack.object_store.v1.container

The Container Class

The Container class inherits from Resource.

class openstack.object_store.v1.container.Container(metadata=None, **attrs)

Process and save metadata known at creation stage

base_path = '/'

The base part of the URI for this resource.

pagination_key = 'X-Account-Container-Count'

Key used for pagination links

allow_create = True

Allow create operation for this resource.

allow_fetch = True

Allow get operation for this resource.

allow_commit = True

Allow update operation for this resource.

allow_delete = True

Allow delete operation for this resource.

allow_list = True

Allow list operation for this resource.

allow_head = True

Allow head operation for this resource.

name

The name of the container.

count

The number of objects in the container.

bytes

The total number of bytes that are stored in Object Storage for the container.

object_count

The number of objects.

bytes_used

The count of bytes used in total.

timestamp

The timestamp of the transaction.

is_newest

If set to True, Object Storage queries all replicas to return the most recent one. If you omit this header, Object Storage responds faster after it finds one valid replica. Because setting this header to True is more expensive for the back end, use it only when it is absolutely needed. Type: bool

read_ACL

The ACL that grants read access. If not set, this header is not returned by this operation.

write_ACL

The ACL that grants write access. If not set, this header is not returned by this operation.

sync_to

The destination for container synchronization. If not set, this header is not returned by this operation.

sync_key

The secret key for container synchronization. If not set, this header is not returned by this operation.

versions_location

Enables versioning on this container. The value is the name of another container. You must UTF-8-encode and then URL-encode the name before you include it in the header. To disable versioning, set the header to an empty string.

history_location

Enables versioning on the container.

content_type

The MIME type of the list of names.

is_content_type_detected

If set to true, Object Storage guesses the content type based on the file extension and ignores the value sent in the Content-Type header, if present. Type: bool

storage_policy

Storage policy used by the container. It is not possible to change policy of an existing container

if_none_match

In combination with Expect: 100-Continue, specify an “If-None-Match: *” header to query whether the server already has a copy of the object before any data is sent.

meta_temp_url_key

The secret key value for temporary URLs. If not set, this header is not returned by this operation.

meta_temp_url_key_2

A second secret key value for temporary URLs. If not set, this header is not returned by this operation.

classmethod new(**kwargs)

Create a new instance of this resource.

When creating the instance set the _synchronized parameter of Resource to False to indicate that the resource does not yet exist on the server side. This marks all attributes passed in **kwargs as “dirty” on the resource, and thusly tracked as necessary in subsequent calls such as update().

Parameters:

kwargs (dict) – Each of the named arguments will be set as attributes on the resulting Resource object.

create(session, prepend_key=True, base_path=None)

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.

Returns:

This Resource instance.

Raises:

MethodNotSupported if Resource.allow_create is not set to True.

set_temp_url_key(proxy, key, secondary=False)

Set the temporary url key for a container.

Parameters:

• proxy (Proxy) – The proxy to use for making this request.

• container – The value can be the name of a container or a Container instance.

• key – Text of the key to use.

• secondary (bool) – Whether this should set the second key. (defaults to False)
