不能污染null_resource

Question

我得到了terraform 0.11.11。图中所示的资源在根模块中

$ terraform graph
digraph {
        compound = "true"
        newrank = "true"
        subgraph "root" {
                "[root] data.template_file.default" [label = "data.template_file.default", shape = "box"]
                "[root] data.template_file.etcd" [label = 
...
                "[root] null_resource.service_resolv_conf" [label = "null_resource.service_resolv_conf", shape = "box"]
...

但试图污染它的人说它不是：

$ terraform taint null_resource.service_resolv_conf
The resource null_resource.service_resolv_conf couldn't be found in the module root.

更新

$ terraform state list|grep resolv_conf 
null_resource.service_resolv_conf[0] 
null_resource.service_resolv_conf[1] 

然后我试着：

$ terraform taint null_resource.service_resolv_conf[0] 

The resource null_resource.service_resolv_conf[0] couldn't be found in the module root. 

和

$ terraform taint null_resource.service_resolv_conf 
The resource null_resource.service_resolv_conf couldn't be found in the module root.

Answer 1

毕竟我找到了解决方案

它出现了，然后当有更多的主机在基于列表的连接中(使用'count')

resource "null_resource" "provision_docker_registry" {
  count      = "${length(local.service_vms_names)}"
  depends_on = ["null_resource.service_resolv_conf"]

  connection {
    user        = "cloud-user"
    private_key = "${file("${path.module}/../ssh/${var.os_keypair}.pem")}"
    host        = "${element(local.service_fip, count.index)}"
  }

通过在点后指定索引来污染资源，例如

$ terraform taint null_resource.provision_docker_registry.0
The resource null_resource.provision_docker_registry.0 in the module root has been marked as tainted!

瞧！

我不可能在文档中找到这一点。希望这对某些人有帮助。

terraform graph为您提供了有关资源及其关系的完整图景。

但它不是一个很好的命令，用于排除故障和了解资源在terraform *.tfstate文件中的命名方式。

我建议使用terraform state list运行，这样你就可以很容易地知道如何污染列表中的某个资源。

terraform state list
terraform taint <copy resource directly from above list>

对于那些来到这个帖子寻找terraform污点/未污点null_resource的人，这里有@victor-m在Cannot taint null_resource上发布的正确且有效的答案

terraform taint -module=name null_resource.name

untaint命令也是如此。
