Object Storage - Get Started

Enable Object Storage

Object Storage is not enabled for a Linode account by default. All that is required to enable Object Storage is to create a bucket or an Object Storage access key. To cancel Object Storage, see the Cancel Object Storage guide.

Generate an Access Key

1. Log into the Linode Cloud Manager.

   Note

   Object Storage is not available in the Linode Classic Manager.

2. Click on the Object Storage link in the sidebar, click the Access Keys tab, and then click the Create an Access Key link.

3. A prompt appears asking you to confirm that you’d like to enable Object Storage. Click Enable Object Storage.

4. The Create an Access Key menu appears.

5. Enter a label for the key pair. This label is how you reference your key pair in the Linode Cloud Manager. Then, click Submit.

6. A window appears that contains your access key and your secret key. Write these down somewhere secure. The access key is visible in the Linode Cloud Manager, but you are not be able to retrieve your secret key again once you close the window.

7. You now have the credentials needed to connect to Linode Object Storage.

Create a Bucket

The Cloud Manager provides a web interface for creating buckets. To create a bucket:

1. If you have not already, log into the Linode Cloud Manager.

2. Click on the Object Storage link in the sidebar, and then click on Create Bucket.

   Note

   If you have not created an access key or a bucket before, you are prompted to enable Object Storage.

3. The Create a Bucket menu appears.

4. Add a label for your bucket. See the Bucket Name section for rules on naming your bucket.

5. Choose a cluster location for the bucket to reside in.

   Note

   A cluster is defined as all buckets hosted by a unique URL; for example: us-east-1.linodeobjects.com, ap-south-1.linodeobjects.com, or eu-central-1.linodeobjects.com.

6. Click Submit. You are now ready to upload objects to your bucket.

Upload an Object to a Bucket

1. If you have not already, log into the Linode Cloud Manager.

2. Click on the Object Storage link in the sidebar. A list of all your buckets appears. Click on the bucket you’d like to begin uploading objects to.

3. Your bucket’s Objects Listing Page appears. In the example, the my-example-bucket does not yet contain any objects. You can use the Upload Files Pane to drag and drop a file from your computer to your object storage bucket.

   Note

   You can drag and drop multiple files to the Upload Files Pane at one time.

   You can also click on the Browse Files button to bring up your computer’s file browser and select a file to upload to your bucket.

4. When the upload has completed, your object is visible on the Objects Listing Page.

   Note

   Individual object uploads are limited to a size of 5GB each, though larger object uploads can be facilitated with multipart uploads. s3cmd and cyberduck do this for you automatically if a file exceeds this limit as part of the uploading process.
   Note

   You can add an AbortIncompleteMultipartUpload lifecycle policy to the buckets to automatically abort unfinished multipart uploads after a certain amount of time. For more information about adding the AbortIncompleteMultipartUpload lifecycle policy, see [Additional Actions] (/docs/guides/how-to-manage-objects-with-lifecycle-policies/#additional-actions).

Control Permissions with ACLs and Bucket Policies

Linode Object Storage allows users to share access to objects and buckets with other Object Storage users. There are two mechanisms for setting up sharing: Access Control Lists (ACLs), and bucket policies. These mechanisms perform similar functions: both can be used to restrict and grant access to Object Storage resources. ACLs can also restrict or grant access to individual objects, but they don’t offer as many fine-grained access modes as bucket policies.

• ACLs (Access Control Lists)

• Bucket Policies

If you can organize objects with similar permission needs into their own buckets, then it’s strongly suggested that you use bucket policies. However, if you cannot organize your objects in this fashion, ACLs are still a good option.

ACLs offer permissions with less fine-grained control than the permissions available through bucket policies. If you are looking for more granular permissions beyond read and write access, choose bucket policies over ACLs.

Additionally, bucket policies are created by applying a written bucket policy file to the bucket. This file cannot exceed 20KB in size. If you have a policy with a lengthy list of policy rules, you may want to look into ACLs instead.

Object Storage Tools

There are a number of tools that are available to help manage Linode Object Storage. This guide explains how to install and use the following options:

• The Linode Cloud Manager can be used to create buckets, and upload and delete objects, as well as create access keys for use with the S3 compatible clients.

• The Linode CLI has an Object Storage plugin and can be used to create and remove buckets, add and remove objects, and convert a bucket into a static site from the command line.

• s3cmd is a powerful command line utility that can be used with any S3-compatible object storage service, including Linode’s. s3cmd can be used to create and remove buckets, add and remove objects, convert a bucket into a static site from the command line, plus other functions like syncing entire directories up to a bucket.

• Cyberduck is a graphical utility available for Windows and macOS and is a great option if you prefer a GUI tool.
