我通过for_each在 Terraform 中使用创建了多个子网 [私有/公共]，如下所示

resource "aws_subnet" "public" {
  for_each = toset(data.aws_availability_zones.azs.names)
  vpc_id = aws_vpc.vpc.id
  cidr_block = cidrsubnet(var.private_ranges,1 ,index(data.aws_availability_zones.azs.names, each.value))
  availability_zone = each.value
  map_public_ip_on_launch = true
  tags = merge(local.common_tags, map("Name", join("-", [local.prefix, index(data.aws_availability_zones.azs.names,each.value )]),
  "Availibility Zone", each.value, "Type", "Public"))

  lifecycle {
    prevent_destroy = false
  }
}

resource "aws_subnet" "private" {
  for_each = toset(data.aws_availability_zones.azs.names)
  vpc_id = aws_vpc.vpc.id
  cidr_block = cidrsubnet(var.private_ranges,1 ,index(data.aws_availability_zones.azs.names, each.value))
  availability_zone = each.value
  tags = merge(local.common_tags, map("Name", join("-", [local.prefix, index(data.aws_availability_zones.azs.names,each.value )]),
  "Availibility Zone", each.value, "Type", "Private"))

  lifecycle { …
