  • count: number of HA servers to deploy (default: 3)

  • ami: instance AMI ID (default: ami-dfdff3c8; RancherOS in us-east-1)
  • key_name: SSH key name in your AWS account for AWS instances (required)
  • instance_type: AWS instance type (default: t2.large for RAM requirement)
  • root_volume_size: size in GB of the instance root volume (default: 16)
  • vpc_cidr: subnet in CIDR format to assign to the VPC (default: 192.168.199.0/24)
  • subnet_cidrs: list of subnet ranges (3 required) (default: ["192.168.199.0/26", "192.168.199.64/26", "192.168.199.128/26")
