所需属性vars元素字符串的不适当值

Question

应用terraform时出错，我正在用云端部署处理terraform。我想从数据locals.tf vars块中的template_file文件中获取ip地址。当我执行terraform应用时，它将显示“属性vars元素字符串所需的不合适的值”。locals.tf

locals {
  workers = {
    "worker-1" = { host_name = "wrkr-1", vm_ip = "90" }
    "worker-2" = { host_name = "wrkr-2", vm_ip = "91" }
    "worker-3" = { host_name = "wrkr-3", vm_ip = "92" }
    "worker-4" = { host_name = "wrkr-4", vm_ip = "93" }
    "worker-5" = { host_name = "wrkr-5", vm_ip = "94" }
    "worker-6" = { host_name = "wrkr-6", vm_ip = "95" }    
  }
  controllers = {
    "controllers-1" = { host_name = "ctrl-1", vm_ip = "87" }
    "controllers-2" = { host_name = "ctrl-2", vm_ip = "88" }
    "controllers-3" = { host_name = "ctrl-3", vm_ip = "89" }
  }
}

config.tf

data template_file "lb_userdata" {
  template = file("${path.module}/cloud-init/lb-cloud-config.yaml")
  vars = {
    network_cidr = var.network_cidr
    controller_ip = local.controllers
    ip_address  = var.loadbalancer_ip
  }
}

感谢你的任何帮助

谢谢

谢谢，我找到了一个技巧，我们可以做到这一点。数据文件如下所示

data template_file "lb_userdata" {
  template = file("${path.module}/cloud-init/lb-cloud-config.yaml")
  vars = {
    network_cidr = var.network_cidr
    controller_ip = join(",",([for k in local.controllers: k.vm_ip ]))
    ip_address  = var.loadbalancer_ip
  }
}

我使用join函数并使用for循环来获得字符串的值。

这是我的lb_cloud_config.yaml文件

%{~ for f in split(",",controller_ip) ~}
server ${network_cidr}.${f}:30793
%{~ endfor ~}
