Question: When trying to deploy to AWS EC2, Spinnaker is asking for a "key name", but the drop-down is empty. What do I do?

Answer: In AWS console, go to EC2 Dashboard. Towards the bottom of left hand side menu, locate "key pair". Click on "Create" and create a new key pair, giving it a name. Once done, after sometime, the drop down in Spinnaker should populate with that name.
