How can I pass a list of values to a block within a resource
问题
我正在尝试使用Terraform从MySQL设置与BigQuery的Datastream连接（文档在此）。文档显示了用于指定要包括哪些表的结构如下：
resource "google_datastream_stream" "default" {
depends_on = [
google_kms_crypto_key_iam_member.key_user
]
stream_id = "my-stream"
desired_state = "NOT_STARTED"
location = "us-central1"
display_name = "my stream"
labels = {
key = "value"
}
source_config {
source_connection_profile = google_datastream_connection_profile.source_connection_profile.id
mysql_source_config {
include_objects {
mysql_databases {
database = "my-database"
mysql_tables {
table = "includedTable"
mysql_columns {
column = "includedColumn"
data_type = "VARCHAR"
collation = "utf8mb4"
primary_key = false
nullable = false
ordinal_position = 0
}
}
}
}
}
}
}
但我想要指定多个要包括的表，而不仅仅是一个。文档中的更多信息如下：
mysql_databases块支持：
database -（必需）数据库名称。
mysql_tables -（可选）数据库中的表。结构如下所示。
mysql_tables块支持：
table -（必需）表名称。
mysql_columns -（可选）模式中的MySQL列。如果未指定为包含/排除对象的一部分，将包含/排除所有内容。结构如下所示。
因此，它说mysql_databases块是我传递要包括的所有表的地方，但示例语法仅显示如何传递一个表，如table = "myTable"。我如何在这里传递一个值列表或类似的东西？我对Terraform还很新，所以也许我错过了一些标准功能。先感谢您的帮助。

I am trying to set up a Datastream connection from MySQL to BigQuery using Terraform (docs here). The docs show this structure for specifying which tables to include:
resource "google_datastream_stream" "default" {
depends_on = [
google_kms_crypto_key_iam_member.key_user
]
stream_id = "my-stream"
desired_state = "NOT_STARTED"
location = "us-central1"
display_name = "my stream"
labels = {
key = "value"
}
source_config {
source_connection_profile = google_datastream_connection_profile.source_connection_profile.id
mysql_source_config {
include_objects {
mysql_databases {
database = "my-database"
mysql_tables {
table = "includedTable"
mysql_columns {
column = "includedColumn"
data_type = "VARCHAR"
collation = "utf8mb4"
primary_key = false
nullable = false
ordinal_position = 0
}
}
}
}
But I want to specify several tables to include not just one. Further info in the docs say:
The mysql_databases block supports:
database - (Required) Database name.
mysql_tables - (Optional) Tables in the database. Structure is documented below.
The mysql_tables block supports:
table - (Required) Table name.
mysql_columns - (Optional) MySQL columns in the schema. When unspecified as part of include/exclude objects, includes/excludes everything. Structure is documented below.
So it says the mysql_databases block is where I pass in the all the tables I want to include but the example syntax only shows how to pass one table like table = "myTable". How can I pass a list of values here or something like that? I'm quite new to Terraform so maybe I'm missing something standard functionality. Thanks in advance.

这是动态创建嵌套块的解决方案：
dynamic "<block_name>" {
for_each = toset(var.<your-var>)
content {
<thing> = <block_name>.value
}
}
英文:
This is the solution to dynamically create nested blocks:
dynamic "<block_name>" {
for_each = toset(var.<your-var>)
content {
<thing> = <block_name>.value
}
}
