如何从 aws_vpn_connection 资源获取 local_ipv4_network_cidr

Question

我在 terraform 中创建了一个 site-2-site vpn：

resource "aws_vpn_connection" "example" {
  customer_gateway_id = # <cgw id>
  transit_gateway_id  = # <tgw id>

  outside_ip_address_type = "PublicIpv4"
  type                    = "ipsec.1"

  local_ipv4_network_cidr  = "192.168.0.0/18"
  remote_ipv4_network_cidr = "10.0.1.0/24"

  static_routes_only = false

}

现在我想在 TGW 路由表中添加一条静态路由：

resource "aws_ec2_transit_gateway_route" "example_route" {
  transit_gateway_route_table_id = # <route table ID>

  destination_cidr_block        = "192.168.0.0/18" # how to replace THIS part with a reference to previous resource??
  transit_gateway_attachment_id = # <attachment ID>
}

我尝试使用tolist(aws_vpn_connection.example.routes)[0].destination_cidr_block （根据 terraform 文档），但显然它是空的

好吧，这显然是我对 terraform 文档的误读——它不仅是attributes exported 也是arguments 。 所以，正如 Marko 所说，我可以使用

aws_vpn_connection.example.local_ipv4_network_cidr
