如何使用 for_each 引用 Terraform 中的另一个资源？

Question

I want to create a nat_gateway that allocates to all the public_su.net ids and eip nate ids however terraform is erroring

│ aws_su.net.su.nets_public is object with 3 attributes

│ │ each.key is "5"

resource "aws_nat_gateway" "natgw" {
    for_each = {
    for i, v in var.subnets : i => v

    if v.type == "public"
  }

  allocation_id = aws_eip.nat_eip[each.key].id
  subnet_id = aws_subnet.subnets_public[each.key].id


  depends_on = [aws_internet_gateway.igw]

}

Answer 1

You are filtering a list in for_each . So that some indexes is missing. Then you are trying to call aws_eip.nat_eip with non-existing index then you are getting error.

If you can share your var.su.nets and terraform error then we can help you to fix the error(s).
