Using Object Storage from 3rd Party Tools

Updated by Chris Little on May 2, 2015


CenturyLink Cloud now has a robust, geo-distributed Object Storage service capable of storing any type of digital content. Perfect for data backups, media distribution, and file transfers, the Object Storage is Amazon S3-compatible and accessible from the Control Portal or via API. CenturyLink Cloud Object Storage is Amazon S3 compatible, which means that a host of tools are readily available for maintaining buckets and interacting with bucket objects.

  2. Install CyberDuck and run the program. It looks like this when it starts up without any Connections (aka: Service Points or Servers) configured. cyberduck new install

  3. In the Control Portal, navigate to the Object Storage service and view the user record that you want to configure CyberDuck to use. Record the Access Key ID and the Secret Access Key for use in the tool. Access Keys

  4. Also you will need the Service Point (aka server) where your bucket exists (or will exist). In the Control Portal, on the Object Storage bucket listing page, either create a new bucket, or click on an existing bucket. When the Bucket Info and Settings page is displayed, copy/save the portion of the bucket URL that follows the bucket name. In this example, the bucket Service Point (server name) is: object storage bucket info

  5. Back in CyberDuck, click the Open Connection icon (upper left corner) in order to configure the connection details for your Object Storage bucket. Select S3 (Amazon Simple Storage) from the drop down. In the Server field, enter the name of the Service point. Leave Port field set to 443. Populate the Username field with your Access Key ID and populate the Password field with your Secret Access key. cyberduck setup connection

  6. After you have configured the Object Storage connection, CyberDuck will list the available buckets at that Connection. You can double-click on a bucket to upload files or even drag-and-drop files into the bucket. cyberduck established connection

  7. Now that CyberDuck is configured to quickly connect to your CenturyLink Cloud Object Storage account and access the stored buckets, you should bookmark the account for easy access. Click the Bookmark icon to navigate to the Bookmark page. cyberduck bookmark page
