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.

Create a container

1. Log in to the dashboard.
2. Select the appropriate project from the drop down menu at the top left.
3. On the Project tab, open the Object Store tab and click Containers category.
4. Click Container.
5. In the Create Container dialog box, enter a name for the container, and then click Create.

You have successfully created a container.

Upload an object

2. Select the appropriate project from the drop down menu at the top left.
3. On the Project tab, open the Object Store tab and click Containers category.
4. Select the container in which you want to store your object.
5. Click the Upload File icon.The Upload File To Container: <name> dialog box appears. <name> is the name of the container to which you are uploading the object.
6. Enter a name for the object.
7. Browse to and select the file that you want to upload.
8. Click Upload File.

Manage an object

To edit an object

2. Select the appropriate project from the drop down menu at the top left.
3. On the Project tab, open the Object Store tab and click Containers category.
4. Select the container in which you want to store your object.
5. Click the menu button and choose Edit from the dropdown list.The Edit Object dialog box is displayed.

1. Log in to the dashboard.
2. Select the appropriate project from the drop down menu at the top left.
3. On the Project tab, open the Object Store tab and click Containers category.
4. Select the container in which you want to store your object.
5. Click the menu button and choose Copy from the dropdown list.
6. In the Copy Object launch dialog box, enter the following values:

   • Path: Specify a path in which the new copy should be stored inside of the selected container.
   • Destination object name: Enter a name for the object in the new container.
7. Click 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.

1. Log in to the dashboard.
2. Select the appropriate project from the drop down menu at the top left.
3. On the Project tab, open the Object Store tab and click Containers category.
4. Select the container in which you want to store your object.
5. Click Upload Object.The Upload Object To Container: <name> dialog box is displayed.<name> is the name of the container to which you are uploading the object.
6. Enter a name for the object.
7. Click 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.

1. Log in to the dashboard.
2. Select the appropriate project from the drop down menu at the top left.
3. On the Project tab, open the Object Store tab and click Containers category.
4. Select the container in which you want to store your object.
5. Click Create Pseudo-folder.The Create Pseudo-Folder in Container <name> dialog box is displayed. <name> is the name of the container to which you are uploading the object.
