Edit a bucket

You can edit some bucket settings after the bucket has been created and after it has had objects that are written to it.


  • This operation requires the System Administrator or Namespace Administrator role in ECS.
  • A System Administrator can edit the settings for a bucket in any namespace.
  • A Namespace Administrator can edit the settings for a bucket in the namespace in which they are the administrator.

To edit a bucket, you must be assigned to the Namespace Administrator or System Administrator role.
