Containers
|
|
==========
|
|
|
|
Lists objects in a container. Creates, shows details for, and
|
|
deletes containers. Creates, updates, shows, and deletes container
|
|
metadata. For more information and concepts about
|
|
containers see `Object Storage API overview
|
|
<https://docs.openstack.org/swift/latest/api/object_api_v1_overview.html>`_.
|
|
|
|
|
|
Show container details and list objects
|
|
=======================================
|
|
|
|
.. rest_method:: GET /v1/{account}/{container}
|
|
|
|
Shows details for a container and lists objects, sorted by name, in the container.
|
|
|
|
Specify query parameters in the request to filter the list and
|
|
return a subset of objects. Omit query parameters to return
|
|
a list of objects that are stored in the container,
|
|
up to 10,000 names. The 10,000 maximum value is configurable. To
|
|
view the value for the cluster, issue a GET ``/info`` request.
|
|
|
|
Example requests and responses:
|
|
|
|
- ``OK (200)``. Success. The response body lists the objects.
|
|
|
|
- ``No Content (204)``. Success. The response body shows no objects.
|
|
Either the container has no objects or you are paging through a
|
|
long list of objects by using the ``marker``, ``limit``, or
|
|
``end_marker`` query parameter and you have reached the end of
|
|
the list.
|
|
|
|
If the container does not exist, the call returns the ``Not Found
|
|
(404)`` response code.
|
|
|
|
Normal response codes: 200, 204
|
|
|
|
Error response codes: 404

Create container
|
|
================
|
|
|
|
.. rest_method:: PUT /v1/{account}/{container}
|
|
|
|
Creates a container.
|
|
|
|
You do not need to check whether a container already exists before
|
|
issuing a PUT operation because the operation is idempotent: It
|
|
creates a container or updates an existing container, as
|
|
appropriate.
|
|
|
|
To create, update, or delete a custom metadata item, use the ``X
|
|
-Container-Meta-{name}`` header, where ``{name}`` is the name of
|
|
the metadata item.
|
|
|
|
.. include:: metadata_header_syntax.inc
|
|
.. include:: metadata_header_encoding.inc
|
|
|
|

Create, update, or delete container metadata
|
|
============================================
|
|
|
|
.. rest_method:: POST /v1/{account}/{container}
|
|
|
|
Creates, updates, or deletes custom metadata for a container.
|
|
|
|
To create, update, or delete a custom metadata item, use the ``X
|
|
-Container-Meta-{name}`` header, where ``{name}`` is the name of
|
|
the metadata item.
|
|
|
|
.. include:: metadata_header_syntax.inc
|
|
.. include:: metadata_header_encoding.inc
|
|
|
|
Subsequent requests for the same key and value pair overwrite the
|
|
previous value.
|
|
|
|
To delete container metadata, send an empty value for that header,
|
|
such as for the ``X-Container-Meta-Book`` header. If the tool you
|
|
use to communicate with Object Storage, such as an older version of
|
|
cURL, does not support empty headers, send the ``X-Remove-
|
|
Container-Meta-{name}`` header with an arbitrary value. For
|
|
example, ``X-Remove-Container-Meta-Book: x``. The operation ignores
|
|
the arbitrary value.
|
|
|
|
If the container already has other custom metadata items, a request
|
|
to create, update, or delete metadata does not affect those items.
|
|
|
|

|
|
|
|
