具有嵌套资源的 Terraform for_each

Question

我在本地使用 for_each，在 bigquery 中创建多个数据集。另一个 for_each 在之前的数据集中创建 table。

问题是我必须用 dataset_ressource.dataset_id.id 之类的数据集引用 table 但我使用 each.value.dataset1.

因此，仅当我运行 “terraform apply” 两次时它才有效

locals {
  bq_settings = {
    "${var.dataset1}" = {description = "description dataset 1"},
  } 
} 

locals {
  table_settings = {
    "${var.table1}" = {dataset_id = "dataset1_test", file = "table1.json"},
  } 
} 



resource "google_bigquery_dataset" "map" {
  for_each  = local.bq_settings
  dataset_id                  = each.key
  description                 = each.value.description
  location                    = var.location
  default_table_expiration_ms = 3600000
  
  labels = {
    env = "default"
  }
}

resource "google_bigquery_table" "map" {
  for_each  = local.table_settings

  dataset_id = each.value.dataset_id   
  table_id   = each.key
  deletion_protection = false

  time_partitioning {
    type = "DAY"
  }

  labels = {
    env = "default"
  }

  schema = file("${path.module}/schema-bq/${each.value.file}")
  
} 
```

第二次有效，因为google_bigquery_dataset和google_bigquery_table没有直接关系。您可以使用 depends_on:

明确添加这样的关系

resource "google_bigquery_table" "map" {
  for_each  = local.table_settings

  dataset_id = each.value.dataset_id   
  table_id   = each.key
  deletion_protection = false

  time_partitioning {
    type = "DAY"
  }

  labels = {
    env = "default"
  }

  schema = file("${path.module}/schema-bq/${each.value.file}")

  depends_on = [google_bigquery_table.map]  
}
