==========
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
Example requests and responses:
- Create a container with no metadata:
::
curl -i $publicURL/steven -X PUT -H "Content-Length: 0" -H "X-Auth-Token: $token"
::
HTTP/1.1 201 Created
Content-Length: 0
Content-Type: text/html; charset=UTF-8

- Create a container with metadata:
::

::
HTTP/1.1 201 Created

- Create a container with an ACL to allow anybody to get an object in the
marktwain container:
::
curl -i $publicURL/marktwain -X PUT -H "X-Auth-Token: $token" -H "X-Container-Read: .r:*"
::

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.
Example requests and responses:
- Create container metadata:
::
curl -i $publicURL/marktwain -X POST -H "X-Auth-Token: $token" -H "X-Container-Meta-Author: MarkTwain" -H "X-Container-Meta-Web-Directory-Type: text/directory" -H "X-Container-Meta-Century: Nineteenth"
