Granting All Accounts the Read Permission for Certain Objects

Scenario

Enterprise A stores a large volume of map data in OBS, and offers the data for public query. This enterprise sets a read permission for all accounts, and provides the data URLs on the Internet. Then all users can read or download the data through the URLs.

Configuration Precautions

In this case, the preset template Object Read-Only allows all accounts to perform the following actions on specified objects in a bucket:

  • GetObject (to obtain object content and metadata)
  • GetObjectVersion (to obtain the content and metadata of a specified object version)
  • GetObjectVersionAcl (to obtain the ACL of a specified object version)
  • GetObjectAcl (to obtain the object ACL)
  • RestoreObject (to restore objects from Archive storage)

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. Choose a policy configuration method you like. Visual Editor is used here.
  6. Configure parameters for a bucket policy.
