Configuring a Bucket ACL

Functions

This operation controls access permissions for buckets. By default, only the creator of a bucket has the permission to read and write the bucket. You can also set other access permissions. For example, you can set a public read policy to grant the read permission to all users.

You can configure an ACL when creating a bucket, and modify or obtain the ACLs of existing buckets using the API operations. A bucket ACL supports a maximum of 100 grants. The PUT method is idempotent. With this method, a new bucket ACL will overwrite the previous bucket ACL. To modify or delete an ACL, you just need to create a new one using the PUT method.

For details about how to use bucket ACLs to manage permissions, see the permission control in the OBS Permission Configuration Guide.
