Also very interested in getting spot instances into the cluster, but looking for a way to:
(a) Mix spot and reserved instances, e.g. there should always be at least N instances dedicated.
(b) Set the spot bid dynamically; I'm guessing this will be a separate tool—any recommendations?
Ok, grand. I was poking through the docs and a lot of it was Terraform-modules-oriented. If you've had success deploying and managing it with the Helm chart, then I'll definitely look into setting it up soonish.
