Granting All Accounts the Public Read Permission for a Bucket

Scenario

If a bucket needs to be accessed by all accounts, you can configure a bucket policy and bucket ACL to grant the access permission to all accounts. The following uses a bucket policy as an example.

Precautions

In this case, the preset template Public Read allows all accounts to perform the following actions on a bucket and the objects in it:

• HeadBucket (to check whether the bucket exists and obtain the bucket metadata)
• GetBucketLocation (to get the bucket location)
• GetObject (to obtain object content and metadata)
• RestoreObject (to restore objects from Archive storage)
• GetObjectVersion (to obtain the content and metadata of a specified object version)

Procedure

1. In the navigation pane of OBS Console, choose Buckets.
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 Policies.
4. On the Bucket Policies page, click Create.
5. Configure a bucket policy.
