route53_record alias keeps being recreated when elb dns_name is not entirely lowercase

[blckct]

Terraform Version

v0.9.8

Affected Resource(s)

• aws_route53_record
• aws_elb.

Terraform Configuration Files

resource "aws_route53_zone" "internal" {
  name = "elbtest.deleteme"
}

resource "aws_elb" "lb" {

  availability_zones=["eu-west-1a"]
  name = "Test"

  "listener" {
    instance_port = 80
    instance_protocol = "HTTP"
    lb_port = 80
    lb_protocol = "HTTP"
  }
}

// Attach the ELB to domain
resource "aws_route53_record" "elb" {
  name = "test.elbtest.deleteme"
  type = "A"
  zone_id = "${aws_route53_zone.internal.zone_id}"
  alias {
    evaluate_target_health = true
    name = "${aws_elb.lb.dns_name}"
    zone_id = "${aws_elb.lb.zone_id}"
  }
}

Expected Behavior

The alias shouldn't be changed since nothing really changed

Actual Behavior

The record gets replaced every time

Probably relates to #1700

FWIW, changing ${aws_elb.lb.dns_name} to ${lower(aws_elb.lb.dns_name)} in the above example will work around this issue.

I have submitted a PR to hopefully fix this: #3119

[bflad]

The fix for this has been merged into master and will be released in v1.8.0 of the provider, expected tomorrow! 🎉

This has been released in terraform-provider-aws version 1.8.0. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading.
