Create and manage object containers
|
|
===================================
|
|
|
|
OpenStack Object Storage (swift) is used for redundant, scalable data storage
|
|
using clusters of standardized servers to store petabytes of accessible data.
|
|
It is a long-term storage system for large amounts of static data which can be
|
|
retrieved and updated.
|
|
|
|
OpenStack Object Storage provides a distributed, API-accessible storage
|
|
platform that can be integrated directly into an application or used to
|
|
store any type of file, including VM images, backups, archives, or media
|
|
files. In the OpenStack dashboard, you can only manage containers and
|
|
objects.
|
|
|
|
In OpenStack Object Storage, containers provide storage for objects in a
|
|
manner similar to a Windows folder or Linux file directory, though they
|
|
cannot be nested. An object in OpenStack consists of the file to be
|
|
stored in the container and any accompanying metadata.

|
|
|
|
#. On the :guilabel:`Project` tab, open the :guilabel:`Object Store` tab and

|
|
|
|
#. Select the appropriate project from the drop down menu at the top left.
|
|
|

|
|
|

|
|
|
|
#. Click the menu button and choose :guilabel:`Copy` from the dropdown list.
|
|
|
|
#. In the :guilabel:`Copy Object` launch dialog box, enter the following
|
|
values:
|
|
|
|
* :guilabel:`Destination Container`: Choose the destination container from
|
|
the list.
|
|
* :guilabel:`Path`: Specify a path in which the new copy should be stored
|
|

|
|
new container.
|
|
|
|
#. Click :guilabel:`Copy Object`.
|
|
|
|
**To create a metadata-only object without a file**
|
|
|
|
You can create a new object in container without a file available and
|
|
can upload the file later when it is ready. This temporary object acts a
|
|
place-holder for a new object, and enables the user to share object
|
|
metadata and URL info in advance.
|
|
|
|
#. Log in to the dashboard.
|
|
|
|
#. Select the appropriate project from the drop down menu at the top left.

|
|
click :guilabel:`Containers` category.

``<name>`` is the name of the container to which you are uploading
|
|
the object.
|
|
|
|
#. Enter a name for the object.
|
|
|
|
#. Click :guilabel:`Update Object`.
|
|
|
|
**To create a pseudo-folder**
|
|
|
|
Pseudo-folders are similar to folders in your desktop operating system.
|
|
They are virtual collections defined by a common prefix on the object's
|
|
name.
|
|
|
|
#. Log in to the dashboard.

|
|
