Amazon web services Terraform：如何从一个资源块创建多个aws子网？

我试图从一个资源块创建多个子网，但出现以下错误

错误：aws_subnet.private:cidr_块必须是单个值，而不是列表

main.tf

resource "aws_subnet" "private" {
  vpc_id                  = "${aws_vpc.vpcname.id}"
  cidr_block              = "${var.private_subnet}"
  availability_zone       = "${data.aws_availability_zones.available.names[count.index]}"
  map_public_ip_on_launch = false

  tags {
    Name        = "${var.private}"
    Environment = "${terraform.workspace}"
  }
}

variable "private_subnet" {
  type    = "list"
  default = []
}

变量。tf

resource "aws_subnet" "private" {
  vpc_id                  = "${aws_vpc.vpcname.id}"
  cidr_block              = "${var.private_subnet}"
  availability_zone       = "${data.aws_availability_zones.available.names[count.index]}"
  map_public_ip_on_launch = false

  tags {
    Name        = "${var.private}"
    Environment = "${terraform.workspace}"
  }
}

variable "private_subnet" {
  type    = "list"
  default = []
}

dev.tfvars

private_subnet = ["10.0.2.0/24", "10.0.3.0/24"]

---

private\u subnet

是一个列表，因此您应该选择单个元素，例如

---

cidr\u block=“${element（var.private\u subnet，count.index）}”

private\u subnet

是一个列表，因此您应该选择单个元素，例如

---

cidr\u block=“${element（var.private\u subnet，count.index）}”

您必须通过利用

count

参数为

var.private\u subnet

列表中的每个条目创建一个资源来创建多个

aws\u子网

资源：

resource "aws_subnet" "private" {
  count                   = "${length(var.private_subnet)}"
  vpc_id                  = "${aws_vpc.vpcname.id}"
  cidr_block              = "${var.private_subnet[count.index]}"
  availability_zone       = "${data.aws_availability_zones.available.names[count.index]}"
  map_public_ip_on_launch = false
}

这将单个aws_子网资源扩展为两个，当terraform对每个资源块进行评估时，每个资源块的值根据

count

的枚举略有不同。

这起作用，但依赖于下面列出的私有子网的另一个资源块代码不起作用<代码>资源“aws_nat_gateway”“nat”{allocation_id=“${aws_eip.eipname.id}”subnet_id=“${aws_subnet.private.id}”依赖于=[“aws_internet_gateway.gw”]标记{Name=“${var.natgateway}”环境=“${terraform workspace}”此操作有效，但依赖于下面列出的专用子网的其他资源块代码无效<代码>资源“aws_nat_gateway”“nat”{allocation_id=“${aws_eip.eipname.id}”subnet_id=“${aws_subnet.private.id}”依赖于=[“aws_internet_gateway.gw”]标记{Name=“${var.natgateway}”环境=“${terraform workspace}}
