Question

我不确定我在做什么错。我有这样的地形：

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
}

我的地形计划将其返回。它抱怨计数，但不确定如何处理。

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]

非常感谢您的帮助。

Answer 1

如错误消息所示，由于您在count中使用了aws_apigatewayv2_domain_name，因此在引用它时应该立即使用索引。

例如：

domain_name = aws_apigatewayv2_domain_name.web[0].id
