Found an issue. I updated this names to actual values

variable "registry_username" {
  type = string
  default = ""
  env = ["REGISTRY_USERNAME"]
}

variable "registry_password" {
  type = string
  sensitive = true
  default = ""
  env = ["REGISTRY_PASSWORD"]
}

This is ambigious. Sometimes you require to update (learn-nomad-cluster-setup/aws/variables.hcl), sometimes not (like here). This is ambigous. =(

Hi @EugenKon I'm going to transfer this issue over to the Waypoint repo, as the folks there will have better context on how to help you out.
