Terraform：如何生成键/值对

Question

我需要从IP地址列表中生成键/值对的映射。

示例输入：

ips = [ "1.2.3.4", "2.3.4.5"]

期望的输出：

pairs = [ {ip_address="1.2.3.4"}, {ip_address="2.3.4.5"} ]

我的TF输入数据位于openstack_networking_port_v2.vip.*.all_fixed_ips.0（任意数量的IP地址），我需要为allowed_address_pairs生成openstack_networking_port_v2参数，例如：

resource "openstack_networking_port_v2" "port" {
  name = "port"
  admin_state_up = "true"
  network_id = "${openstack_networking_network_v2.net-backend.id}"
  allowed_address_pairs = [ 
   { ip_address = "1.2.3.4" },
   { ip_address = "2.3.4.5" } 
  ]
}

但当然，从以下资源动态声明allowed_address_pairs：

resource "openstack_networking_port_v2" "vip" {
  name = "vip-${count.index}"
  network_id = "${openstack_networking_network_v2.net-backend.id}"
  admin_state_up = "true"
  count = "10"
}

有任何线索吗？
