Configuring bucket access permissions in Amazon Lightsail

Last updated: July 14, 2021

Use bucket access permissions to control public (unauthenticated) read-only access to objects in a bucket. You can make a bucket private or public (read-only). You can also make a bucket private, while having the option to make individual objects public (read-only).

Important

When you make a bucket public (read-only), you make all objects in the bucket readable by anyone on the internet through the bucket's URL (for example, https://DOC-EXAMPLE-BUCKET.us-east-1.amazonaws.com/media/sailbot.jpg). Don't make a bucket public (read-only) if you don't want anyone on the internet to have access to your objects.

For more information about permission options, see Understanding bucket permissions in Amazon Lightsail. For more information about security best practices, see Security Best Practices for Amazon Lightsail object storage. For more information about buckets, see Object storage in Amazon Lightsail.

Configure bucket access permissions

Complete the following procedure to configure access permissions for a bucket.

  1. Sign in to the Lightsail console.

  2. On the Lightsail home page, choose the Storage tab.

  3. Choose the name of the bucket for which you want to configure access permissions.

  4. Choose the Permissions tab.

    The Bucket access permissions section of the page displays the currently configured access permission for the bucket.

  5. Choose Change permission to change the bucket access permissions.

  6. Choose one of the following options:

    • All objects are private – All objects in the bucket are readable only by you or anyone you give access to.

    • Individual objects can be made public (read-only) – Objects in the bucket are readable only by you or anyone you give access to, unless you specify an individual object to be public (read-only). For more information about individual object access permissions, see Configuring access permissions for individual objects in a bucket in Amazon Lightsail.

      We recommend that you select the Individual objects can be made public (read-only) option only if you have a specific need to do so, such as making only some of the objects in your bucket public while keeping all other objects private. For example, some WordPress plugins require that your bucket allows individual objects to be made public. For more information, see Tutorial: Connecting a WordPress instance to an Amazon Lightsail bucket and Tutorial: Using an Amazon Lightsail bucket with a Lightsail content delivery network distribution.

    • All objects are public (read-only) – All objects in the bucket are readable by anyone on the internet.

      Important

      When you make a bucket public (read-only), you make all objects in the bucket readable by anyone on the internet through the bucket's URL (for example, https://DOC-EXAMPLE-BUCKET.us-east-1.amazonaws.com/media/sailbot.jpg). Don't make a bucket public (read-only) if you don't want anyone on the internet to have access to your objects.

  7. Choose Save to save the change. Otherwise, choose Cancel.

    The following changes are implemented depending on which bucket access permission you change to:

    • All objects are private - All objects in the bucket become private even if they were previously configured with a Public (read-only) individual object access permission.

    • Individual objects can be made public (read-only) - Objects that were previously configured with a Public (read-only) individual object access permission become public. You can now configure individual object access permissions for objects.

    • All objects are public (read-only) - All objects in the bucket become public (read-only) even if they were previously configured with a Private individual object access permission.
