terraform multiple aws route53 alias records under locals - amazon-web-services

Question

I have a set of AliasRecords under terraform locals and wanted to map them under terraform's resource "aws_route53_record" . Below is the locals value:
locals {
AWSAliasRecordSets = [
{
Name = "api-dev.example.com.",
Type = "A",
AliasTarget = {
HostedZoneId = "EXAMPLE",
DNSName = "kjhskdjhf.cloudfront.net.",
EvaluateTargetHealth = false
}
},
{
Name = "api.example.com.",
Type = "A",
AliasTarget = {
HostedZoneId = "EXAMPLE",
DNSName = "jsdhgfjkdshf.cloudfront.net.",
EvaluateTargetHealth = false
}
}
]
}
What I am doing is :
locals {
FlatAWSAliasRecordSets = merge([
for idx, AWSAliasRecordSet in local.AWSAliasRecordSets:
{
for AliasTarget in AWSAliasRecordSet.AliasTarget:
"${idx}-${AliasTarget}" => {
HostedZoneId = AliasTarget["HostedZoneId"]
DNSName = AliasTarget["DNSName"]
EvaluateTargetHealth = AliasTarget["EvaluateTargetHealth"]
}
}
]...)
}
resource "aws_route53_record" "alias_records" {
for_each = local.FlatAWSAliasRecordSets
zone_id = each.value["HostedZoneId"]
name = each.value["AliasTarget"].Name
type = each.value["AliasTarget"].Type
alias {
zone_id = each.value["HostedZoneId"]
name = each.value["AliasTarget"].Name
evaluate_target_health = each.value["EvaluateTargetHealth"]
}
}
and when pushing to AWS ( terraform apply), it fails with below error:
│ on main.tf line 508, in locals:
│ 508: EvaluateTargetHealth = AliasTarget["EvaluateTargetHealth"]
│ This value does not have any indices.

Your AWSAliasRecordSets does not require flattening, as it is already flat. Thus you can go use regular count for it.
resource "aws_route53_record" "alias_records" {
count = length(local.AWSAliasRecordSets)
zone_id = local.AWSAliasRecordSets[count.index]["AliasTarget"].HostedZoneId
name = local.AWSAliasRecordSets[count.index].Name
type = local.AWSAliasRecordSets[count.index].Type
alias {
zone_id = local.AWSAliasRecordSets[count.index]["AliasTarget"].HostedZoneId
name = local.AWSAliasRecordSets[count.index].DNSName
evaluate_target_health = each.value["AliasTarget"].EvaluateTargetHealth
}
}
You also have to double check your use of Name and DNSName. Your current usage does not seem right to me, but this would be a new issue if this is really the case.
