AWS Terraform passing of multiple arn for Cloudfront function

I like to do a dynamic function_assocation to an AWS CloudFront resource. Instead of defining each function, I did something like the below.

resource "aws_cloudfront_function" "functions" {
  for_each = var.cf_lambda_functions

  name    = each.value.name
  comment = each.value.description
  runtime = each.value.runtime
  publish = each.value.publish
  code    = each.value.code
}

and for the function_association, I did something like the below.

dynamic "function_association" {
  for_each = aws_cloudfront_function.functions
  content {
    event_type = "viewer-request"
    function_arn = each.value.arn
  }
}

this gives me an error: each.value cannot be used in this context. How do you do this by passing multiple ARN of functions?

CodePudding user response：

In dynamic blocks you can't use each. Instead it should be function_association in your case:

dynamic "function_association" {
  for_each = aws_cloudfront_function.functions
  content {
    event_type = "viewer-request"
    function_arn = function_association.value.arn
  }
}
