I noticed there is already a
-subnet=... The AWS subnet to deploy to (single instance apps only)
parameter but not for ELB-based deployments, yet. Is it already possible to define which vpc/subnets should be used for a deployment?
Currently all subnets of the default VPC are associated with the automatically created auto-scaling groups. The auto-scaling groups will then launch instances across them in a balanced fashion.
