CDKTF Iterator On AWS Resources
问题
我已经查看了CDKTF TerraformIterator的源代码以及AWS子网，尝试找到一种在设置for_each时迭代子网的方法。由于迭代器需要一个字符串列表，我不确定如何做到这一点，因为我没有看到从该类返回子网ID的任何内容。以下是一些Python伪代码：
public_subnets = Subnet(self, 'default-public',for_each = public_subnet_iterator,availability_zone_id = public_subnet_iterator.get_string('availability_zone'),cidr_block = public_subnet_iterator.get_string('CIDR'),vpc_id = default_vpc.id,tags = Tags.commons_with_name('default-public'))route_table = RouteTable(self, 'public-subnets',vpc_id = default_vpc.id,RouteTableRoute(cidr_block = '0.0.0.0/0',gateway_id = default_gateway.id),tags = Tags.commons_with_name('public-subnet-routing'))routable_subnets = TerraformIterator.fromList(public_subnets.?????)RouteTableAssociation(self, 'public-subnet-routes',for_each = routable_subnets,etc...)
如何迭代子网以生成这些路由表关联？
英文:
I've gone through the source code of CDKTF TerraformIterator, and the AWS Subnets to try and find a way to iterate over Subnet when setting for_each. I'm not sure how to do this as the iterator requires a list of strings and I don't see anything that would return subnet ids from that class. Here is some Python pseudo code:
public_subnets = Subnet(self, 'default-public',for_each = public_subnet_iterator,availability_zone_id = public_subnet_iterator.get_string('availability_zone'),cidr_block = public_subnet_iterator.get_string('CIDR'),vpc_id = default_vpc.idtags = Tags.commons_with_name('default-public'))route_table = RouteTable(self, 'public-subnets',vpc_id = default_vpc.id,RouteTableRoute(cidr_block = '0.0.0.0/0',gateway_id = default_gateway.id),tags = Tags.commons_with_name('public-subnet-routing'))routable_subnets = TerraformIterator.fromList(public_subnets.?????)RouteTableAssociation(self, 'public-subnet-routes',for_each = routable_subnets,etc...)
How can I iterate over the subnets to generate these route table associations?

这在CDKTF目前不受支持，但在即将推出的版本0.16中可能会发生改变。请参阅 https://github.com/hashicorp/terraform-cdk/issues/2024 和 https://github.com/hashicorp/terraform-cdk/pull/2739 以获取更多上下文信息。在它受支持之前，您需要使用 逃生舱 来使其工作，或者如果 publicSubnetIterator 使用静态列表，您还可以使用 for 循环。
英文:
This is currently not supported in CDKTF, but will likely change in the upcoming version 0.16. See https://github.com/hashicorp/terraform-cdk/issues/2024 and https://github.com/hashicorp/terraform-cdk/pull/2739 for more context. Until it's supported you would need to use an escape hatch to make it work or if the publicSubnetIterator is using a static list you could also use a for loop.
