  # version = "1.0.3"       # point to a version
  cleanup = false
  enable_server = true
  ssh_ip = "127.0.0.1"
  ssh_user = var.ssh_user
  ssh_private_key = var.ssh_private_key
  cluster_main = var.cluster_main
  port = "22"
  public_ip = "172.23.186.134"
  nomad_http = 4646
  nomad_rpc = 4647
  nomad_serf = 4648
