terraform 无法访问模块输出

Question

在 Terraform 中使用此认知模块

https://github.com/lgallard/terraform-aws-cognito-user-pool/blob/master/outputs.tf#L34

我无法访问输出变量

output "domain_cloudfront_distribution_arn" {
  description = "The ARN of the CloudFront distribution"
  value       = var.enabled ? join("", module.aws_cognito_user_pool_stardust.domain.*.cloudfront_distribution_arn) : null
}

抛出这个错误

这是我的 main.tf 文件

module "aws_cognito_user_pool_stardust" {

  source  = "lgallard/cognito-user-pool/aws"
  version = "0.14.2"
  .....

}

Answer 1

这是模块内部的定义：

output "domain_cloudfront_distribution_arn" {
  description = "The ARN of the CloudFront distribution"
  value       = var.enabled ? join("", aws_cognito_user_pool_domain.domain.*.cloudfront_distribution_arn) : null
}

您要做的只是将其作为主模块的输出传递，因此您需要定义：

output "domain_cloudfront_distribution_arn" {
  description = "The ARN of the CloudFront distribution"
  value       = module.aws_cognito_user_pool_stardust.domain_cloudfront_distribution_arn
}
