问题描述
我不确定我做错了什么.我有这样的地形:
I'm unsure what I'm doing wrong. I have terraform as such:
resource "aws_apigatewayv2_domain_name" "web" {
domain_name = var.web_url
count = var.web_url != "" ? 1 : 0
domain_name_configuration {
certificate_arn = var.web_acm_arn
endpoint_type = "REGIONAL"
security_policy = "TLS_1_2"
}
}
resource "aws_apigatewayv2_api_mapping" "web" {
api_id = aws_apigatewayv2_api.web.id
domain_name = aws_apigatewayv2_domain_name.web.id
stage = aws_apigatewayv2_stage.web_stage.id
count = var.web_url != "" ? 1 : 0
}
我的 terraform 计划返回了这个.它抱怨计数,但不确定如何处理它.
My terraform plan returns this. it complains about count, but unsure what to do with it.
Terraform v0.12.24

2020/07/29 06:20:46 [DEBUG] Using modified User-Agent: Terraform/0.12.24 TFC/29e17ad841
Error: Missing resource instance key
on ../modules/web/api.tf line 37, in resource "aws_apigatewayv2_api_mapping" "web":
37: domain_name = aws_apigatewayv2_domain_name.web.id
Because aws_apigatewayv2_domain_name.web has "count" set, its
attributes must be accessed on specific instances.
For example, to correlate with indices of a referring resource, use:
aws_apigatewayv2_domain_name.web[count.index]
感谢您的帮助.
推荐答案
正如错误消息所示,由于您在 aws_apigatewayv2_domain_name
中使用了 count
,因此应该使用引用时立即索引.
As the error message suggest, since you've used count
in your aws_apigatewayv2_domain_name
, you should use index now when you refer to it.
例如:
domain_name = aws_apigatewayv2_domain_name.web[0].id
