AWS Terraform passing of multiple arn for Cloudfront function_association

Question

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?

Answer 1

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
  }
}
