Configuring a Bucket ACL

1. In the navigation pane of OBS Console, choose Object Storage.
2. In the bucket list, click the bucket you want to operate. The Objects page is displayed.
3. In the navigation pane, choose Permissions > Bucket ACLs.
4. On the Bucket ACLs page, choose a permission from Private, Public Read, and Public Read/Write to grant bucket ACL permission for anonymous users.
   

   1. After you change Public Read or Public Read/Write to Private, only the bucket owner or object owner has the access.
   2. After you change Private to Public Read, anyone can read objects in the bucket. No identity authentication is required.
   3. After you change Private to Public Read/Write, anyone can read, write, and delete objects in the bucket. No identity authentication is required.

7. In the middle of the page, click Add to apply specific ACL permissions to an account.

   Enter an account ID and specify ACL permissions for the account. You can obtain the account ID from the My Credentials page.
