Granting Other Accounts the Specified Permissions for a Bucket

Scenario

This topic describes how to grant other Huawei Cloud accounts (excluding the IAM users under them) specific operation permissions for OBS buckets. For details about how to grant permissions to an IAM user, see Granting IAM Users Under an Account the Access to a Bucket and the Resources in It.

The following example explains how to grant the permissions to configure a bucket ACL and obtain the bucket ACL configuration information. If you need to configure other permissions, select the corresponding actions from the Action Name drop-down list in the bucket policy. For details about the actions supported by OBS, see Action/NotAction.

Recommended Configuration

You are advised to use bucket policies to grant permissions to other accounts.

Configuration Precautions

After the configuration is complete, the authorized account can configure and obtain a bucket ACL by using APIs or SDKs or by adding external buckets through OBS Browser+. To do this by adding external buckets, the ListBucket permission is also required. Currently, access to buckets of other accounts is not allowed on OBS Console.

Procedure

1. In the navigation pane of OBS Console, choose Object Storage.
2. In the bucket list, click the bucket name you want to go to the Objects page.
3. In the navigation pane, choose Permissions > Bucket Policy.
4. On the Bucket Policies page, click Create.
5. Locate the row containing Custom policy and click Create Custom Policy.
