<p>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.</p> <p> <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 href="https://docs.aws.amazon.com/opsworks/latest/userguide/opsworks-security-users.html">Managing User Permissions</a>.</p> <p>This call accepts only one resource-identifying parameter.</p>
