   aws_secret_access_key: ""
   aws_ssh_keypair: ""
   aws_default_region: ""
   aws_vpc_cidr_block : "10.250.192.0/18"
   aws_cidr_subnets_private : '["10.250.192.0/20","10.250.208.0/20"]'
   aws_cidr_subnets_public : '["10.250.224.0/20","10.250.240.0/20"]'
   aws_bastion_size : "t2.medium"
   aws_kube_master_num : 1
   aws_kube_master_size : "t2.medium"
   aws_etcd_num : 1
   aws_etcd_size : "t2.medium"
   aws_kube_worker_num : 1
   aws_kube_worker_size : "t2.medium"
