Granting an IAM User the Permissions to Create and List Buckets

Scenario

This topic describes how to grant an IAM user the permissions to create and list buckets. An IAM user with this permission can create and list buckets. The created buckets are owned by the account of the IAM user. The IAM user can also view all buckets under the account.

Recommended Configuration

To create and list buckets, you need OBS-level permissions, which can be configured on IAM.

Procedure

1. Log in to the management console using a cloud service account.
2. On the top menu bar, choose Service List > Management & Deployment > Identity and Access Management.
3. In the navigation pane, choose Permissions.
4. Click Create Custom Policy in the upper right corner.
5. Configure a custom policy.

   Scope	Use the default value Global services.

6. Click OK.
7. Create a user group and assign permissions.

   Apply the created custom policy to the user group by following the instructions in the IAM document.
