Can you auto-launch/manage external load balancers [via AWS] with Rancher/K8?

Hello all,

I’m trying to understand the capabilities, and scope of Rancher/K8.

I have setup a new K8 cluster via Rancher on AWS, using the Quick Start Guide. Then to test the load-balancing functionality I am rolling out the Guestbook example.

  1. Is it possible to have K8 automatically create/teardown LBs in AWS via a K8 Service? Or,
  2. Is the recommended model to manually create your LBs, and explicitly add into your Service definition?

Please let me know if I’ve missed something in the documentation.
