aws_directory_service_directory returns list of empty elements for dns_ip_addresses

[bz-keitaro-kobayashi]

Terraform Version

0.8.2. Rolling back to 0.8.1 and using the same tfstate works.

Affected Resource(s)

• aws_directory_service_directory

Terraform Configuration Files

resource "aws_directory_service_directory" "central" {
	name = "directory.internal"
	password = "A VERY str0ng passw0rd"
	size = "Small"

	vpc_settings {
		vpc_id = "vpc-ca9448ae"
		subnet_ids = [
			"subnet-f22e88aa",
			"subnet-cca03eba"
		]
	}

	description = "Central authentication / authorization directory for all HRMOS instances"

	type = "SimpleAD"
}

tfstate

Expected Behavior

$ terraform console
> aws_directory_service_directory.central.dns_ip_addresses
[
  10.238.196.254,
  10.238.195.94
]

Actual Behavior

$ terraform console
> aws_directory_service_directory.central.dns_ip_addresses
[
,

]

Just verified that the same behaviour also happens with output

% terraform show
aws_directory_service_directory.central:
  id = d-92672181ec
  access_url = d-92672181ec.awsapps.com
  alias = d-92672181ec
  connect_settings.# = 0
  description = Central authentication / authorization directory for all HRMOS instances
  dns_ip_addresses.# = 2
  dns_ip_addresses.1702074263 = 10.0.1.160
  dns_ip_addresses.263491012 = 10.0.2.61
  enable_sso = false
  name = directory.internal
  password = PasswordMustBeCharsAndNumb3rs
  short_name = directory
  size = Small
  type = SimpleAD
  vpc_settings.# = 1
  vpc_settings.0.subnet_ids.# = 2
  vpc_settings.0.subnet_ids.1976703249 = subnet-6f965d08
  vpc_settings.0.subnet_ids.3331643916 = subnet-b55dbffc
  vpc_settings.0.vpc_id = vpc-36b51f51

Then terraform output of the following causes this:

output "dns_addresses" {
  value = ["${aws_directory_service_directory.central.dns_ip_addresses}"]
}

Outputs:

dns_addresses = [
    ,

]

I believe #10920 will fix this. It addresses problems with treating sets like lists. Pull down my fork and build it and see what you get. If it doesn't work for you, I might need to revisit my PR.

I've confirmed that #11042 fixes this problem in my instance.

$ ~/go/bin/terraform --version
Terraform v0.8.3-dev (1cec04b8a715c9601cdc0ddf8291f441f49aa024)
$ ~/go/bin/terraform console
> aws_directory_service_directory.central.dns_ip_addresses
[
  10.238.195.94,
  10.238.196.254
]

Dup of #10908. Thanks!
