如何将Terraform计数从资源传递到模块？

Question

如何将从资源创建的值列表传递给期望项列表的模块？我试着运行[count.index]并回复列表[0]中的第一项，但是我得到的消息是，您只能向resource & data块传递一个count对象。

resource "aws_subnet" "private_subnets" {
  count                   = length(data.aws_availability_zones.available.names)
  vpc_id                  = data.aws_vpc.selected.id
  cidr_block              = "192.168.${10 + count.index}.0/24"
  availability_zone       = data.aws_availability_zones.available.names[count.index]
  map_public_ip_on_launch = false

  tags = {
    Name                  = "private-subnet"
  }

module "my_module" {
  source                        = "../../"
  cluster_name                  = local.cluster_name
  subnets                       = aws_subnet.public_subnets[count.index].id

Terraform版本0.12+拥有所有的好东西！

我更新了对资源的调用，以循环如下所示：

[ for subnet in aws_subnet.public_subnets: subnet.id ]
