Terraform YAML配置对象没有属性名。

Question

我正在努力调试yaml文件中的一个问题，该文件每个条目包含两个属性：

topics:
  - name: topic_one
    partitions: 24
  - name: topic_two
    partitions: 1
  - name: topic_three
    partitions: 12
  - name: topic_four
    partitions: 6

我把这个拉到TF里

locals {
  confluent = yamldecode(file("./confluent.yaml"))["topics"]

  confluent_topics = flatten([for topic in local.confluent :
  {
    "name"       = topic.name
    "partitions" = topic.partitions
  }])
}

进入模块时：

module "confluent" {
  source = "./modules/confluent-cloud"
  count  = var.confluent_cluster ? 1 : 0
  topics = local.confluent_topics
  
  region = var.region
}

然后在模块中：

resource "confluent_kafka_topic" "kafka" {
  for_each = {
    for topic in var.topics : topic.name => name
  }  

  kafka_cluster {
    id = confluent_kafka_cluster.kafka.id
  }
  topic_name = each.value.name
  partitions_count = each.value.partitions
  ...

我试过了几乎每一个组合，并且我已经将模块variables.tf中的变量类型设置为几乎所有可以想象的东西。但错误是，它认为对象没有一个名为partitions的属性--我尝试过简化本地而不平缓列表，我尝试了很多不同的变体。但总是这样；

│ Error: Unsupported attribute
│
│   on main.tf line 40, in locals:
│   40:     "partitions" = topic.partitions
│
│ This object does not have an attribute named "partitions".

控制台给了我：

> local.confluent
[
  {
    "name" = "topic_one"
    "partitions" = 24
  },
  {
    "name" = "topic_two"
    "partitions" = 1
  },
  {
    "name" = "topic_three"
    "partitions" = 12
  },
  {
    "name" = "topic_four"
    "partitions" = 6
  }

在扁平的本地控制台上只返回：

> local.confluent_topics
(known after apply)

...which有点令人费解，因为我认为它应该知道这一点，而不适用。我确信这不是我的问题。

最烦人的是我以前做过这件事。因此，我想知道这是否是TF版本的情况，必须以不同的方式处理？

您的逻辑都很好，除了循环属性name。您不能拥有name属性&从它获取partitions字段。它只能从topic对象中获取。

试试这个..。

resource "confluent_kafka_topic" "kafka" {
  for_each = {
    for topic in var.topics : topic.name => topic
  }  

  kafka_cluster {
    id = confluent_kafka_cluster.kafka.id
  }
  topic_name = each.value.name
  partitions_count = each.value.partitions
  ...

您有唯一的键形式的topic.name & topic是具有partitions字段的对象。
