Question

我定义了一个没有自定义卷附件的实例。这是别人成功创建的。现在，我尝试添加另一个实例，除了

资源ID
openstack_compute_instance_v2.name和
它具有附加的卷。

.tf文件的相关位：

resource "openstack_compute_instance_v2" "foo_1" {
  name            = "foo_1"
  image_name      = "…"
  flavor_name     = "…"
  key_pair        = "${var.key_pair}"
  security_groups = […]
}

resource "openstack_blockstorage_volume_v2" "foo_volume_1" {
  name = "foo_volume_1"
  size = 100
}

resource "openstack_blockstorage_volume_attach_v2" "foo_volume_1_attachment" {
  volume_id = "${openstack_blockstorage_volume_v2.foo_volume_1.id}"
  host_name = "${openstack_compute_instance_v2.foo_1.name}"
}

当我尝试TF_LOG=TRACE terraform apply -target=openstack_compute_instance_v2.foo_1时，得到以下相关输出：

由于使用几乎相同的openstack_compute_instance_v2声明成功创建了另一个实例，因此我怀疑问题实际上出在文档host_name的确不正确的地方。在这种情况下是否应该指向实例的名称？如果没有，那应该指向什么？

错误消息原来是红色鲱鱼-我已使用相关信息更新了问题。问题在于，当指定依赖于密钥对的目标实例时，依赖关系无法解决，因此不会创建密钥对。由于密钥对是特定于帐户而不是租户的，因此terraform尝试创建一个引用不存在的密钥对的实例。

有趣的是，此命令对已经应用了其余架构的人员有效，因为他们的密钥对已经创建。

如何指定openstack_blockstorage_volume_attach_v2.host_name？
