Release note for CHANGELOG:

* resource/aws_autoscaling_group: Prevent unexpected differences in `tags` for Terraform 0.11 and earlier with boolean `propagate_at_launch` values

One of the major improvements internally with Terraform 0.12's type system is that providers and the core logic agree on a resource schema and its normalization during configuration parsing so the state and difference handling is more consistent. In Terraform 0.11 and earlier, a quirky behavior with raw boolean values is that they could be converted to string "0" and "1" values based on various factors such as passing through functions. With recent changes to the aws_autoscaling_group resource to fix its handling of the tags attribute (to prevent d.Set() errors and testing panics in the upcoming Terraform Plugin SDK 2.0.0), this behavior was highlighted as unexpected perpetual differences. This cannot be caught in the 0.12 shimmed acceptance testing framework and therefore is manually tested by the below configuration and reproduction steps.

NOTE: The tags argument will be deprecated and removed in a future major version of the Terraform AWS Provider since it was designed as a workaround for Terraform 0.11 and earlier configurations. There are very few, if any, other Terraform AWS Provider attributes represented as a set of maps. In Terraform 0.12 and later, the tag argument more appropriately represents Auto Scaling Group resource tags as configuration blocks with strongly typed nested arguments and can be dynamically built via the dynamic configuration language feature. That deprecation is out of scope for this changeset though and likely will not occur until after Terraform AWS Provider version 3.0.0.

Given the following Terraform 0.11 compatible configuration with raw boolean values:

terraform {
  required_version = "0.11.14"
}

provider "aws" {
  region  = "us-east-2"
  version = "2.67.0"
}

locals {
  test = [
    {
      key                 = "localkey1"
      value               = "localvalue1"
      propagate_at_launch = true
    },
    {
      key                 = "localkey2"
      value               = "localvalue2"
      propagate_at_launch = true
    },
  ]
}

data "aws_ami" "test" {
  most_recent = true
  owners      = ["amazon"]

  filter {
    name   = "name"
    values = ["amzn-ami-hvm-*-x86_64-gp2"]
  }
}

data "aws_availability_zones" "available" {
  state = "available"

  filter {
    name   = "opt-in-status"
    values = ["opt-in-not-required"]
  }
}

resource "aws_launch_template" "test" {
  name_prefix   = "test"
  image_id      = "${data.aws_ami.test.id}"
  instance_type = "t2.micro"
}

resource "aws_autoscaling_group" "test" {
  availability_zones = ["${data.aws_availability_zones.available.names[0]}"]
  desired_capacity   = 0
  max_size           = 0
  min_size           = 0
  tags               = ["${concat(list(map("key", "resourcekey1", "value", "resourcevalue1", "propagate_at_launch", true)), local.test)}"]

  launch_template {
    id      = "${aws_launch_template.test.id}"
    version = "${aws_launch_template.test.default_version}"
  }
}

output "tags" {
  value = "${aws_autoscaling_group.test.tags}"
}

In Terraform 0.12 and later, the `tag` argument more appropriately represents Auto Scaling Group resource tags as configuration blocks with strongly typed nested arguments and can be dynamically built via the `dynamic` configuration language feature. That deprecation is out of scope for this changeset though and likely will not occur until after Terraform AWS Provider version 3.0.0. Given the following Terraform 0.11 compatible configuration with raw boolean values: ```hcl terraform { required_version = "0.11.14" } provider "aws" { region = "us-east-2" version = "2.67.0" } locals { test = [ { key = "localkey1" value = "localvalue1" propagate_at_launch = true }, { key = "localkey2" value = "localvalue2" propagate_at_launch = true }, ] } data "aws_ami" "test" { most_recent = true owners = ["amazon"] filter { name = "name" values = ["amzn-ami-hvm-*-x86_64-gp2"] } } data "aws_availability_zones" "available" { state = "available" filter { name = "opt-in-status" values = ["opt-in-not-required"] } } resource "aws_launch_template" "test" { name_prefix = "test" image_id = "${data.aws_ami.test.id}" instance_type = "t2.micro" } resource "aws_autoscaling_group" "test" { availability_zones = ["${data.aws_availability_zones.available.names[0]}"] desired_capacity = 0 max_size = 0 min_size = 0 tags = ["${concat(list(map("key", "resourcekey1", "value", "resourcevalue1", "propagate_at_launch", true)), local.test)}"] launch_template { id = "${aws_launch_template.test.id}" version = "${aws_launch_template.test.default_version}" } } output "tags" { value = "${aws_autoscaling_group.test.tags}" } ``` Applying twice has a perpetual difference: ```console $ terraform0.11.14 init Initializing provider plugins... - Checking for available provider plugins on https://releases.hashicorp.com... - Downloading plugin for provider "aws" (2.67.0)...
