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.

   Table 1 Parameters for configuring a custom policy

   Parameter	Description
   Policy Name	Enter a policy name.
   Policy View	Select one based on your own habits. Visual editor is used here.
   Policy Content	Select Allow. Select Object Storage Service (OBS). Select obs🪣CreateBucket from ReadWrite actions and obs🪣ListAllMyBuckets from ListOnly actions. Select All for resources.
   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.

8. Add the IAM user you want to authorize to the created user group.
   

   Due to data caching, it takes about 10 to 15 minutes for a custom policy to take effect.
