  Describes Amazon ECS clusters that are registered with a stack. If you specify only a stack ID, you can use the
  <code>MaxResults</code> and <code>NextToken</code> parameters to paginate the response. However, AWS OpsWorks
  Stacks currently supports only one cluster per layer, so the result set has a maximum of one element.

  <b>Required Permissions</b>: To use this action, an IAM user must have a Show, Deploy, or Manage permissions
  level for the stack or an attached policy that explicitly grants permission. For more information about user
  permissions, see <a
