Description

AWS released a new feature for Route53 Resolver to write DNS queries to a log destination. See *QueryLog* actions in the API Reference.

New or Affected Resource(s)

• aws_route53_resolver_query_log_config
• aws_route53_resolver_query_log_config_association
• aws_route53_resolver_query_log_config_policy *

* I'm not sure aws_route53_resolver_query_log_config_policy is required. I went through a RAM-sharing scenario in the console, and reviewing CloudTrail, do not see any explicit API methods called regarding these policies. It may just be a permission required behind the scenes.

Potential Terraform Configuration

resource "aws_route53_resolver_query_log_config" "my_query_log" {
  name = "my_query_log"
  destination_arn = "arn:aws:s3:::my_query_s3_bucket"
  tags = {
    Environment = "Prod"
  }
}

resource "aws_route53_resolver_query_log_config_association" "my_vpc_query_log" {
  query_log_config_id=aws_route53_resolver_query_log_config.my_query_log.id
  resource_id = "vpc-01234abcde"
}

resource "aws_route53_resolver_query_log_config_policy" "my_query_log_policy" {
  account_arn="0123456789012"
  policy=<<EOF
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal":
      {
        "AWS": [
          "123456789012"
        ]
      },
      "Action": [
        "route53resolver:AssociateResolverQueryLogConfig",
        "route53resolver:DisassociateResolverQueryLogConfig",
        "route53resolver:ListResolverQueryLogConfigAssociations",
        "route53resolver:ListResolverQueryLogConfigs"
      ],
      "Resource": [
        "${aws_route53_resolver_query_log_config.my_query_log.arn}"
      ]
    }
  ]
}
EOF
}

@jgardsentry I agree that aws_route53_resolver_query_log_config_policy isn't required (at least not to get most scenarios working).
