launch_template_version is not being used about terraform-aws-ec2-autoscale-group HOT 3 CLOSED

No, I meant this https://github.com/cloudposse/terraform-aws-ec2-autoscale-group/search?q=launch_template_version&unscoped_q=launch_template_version

from terraform-aws-ec2-autoscale-group.

@martinhanzik thanks!
Did you mean this https://github.com/cloudposse/terraform-aws-ec2-autoscale-group/blob/master/main.tf#L99?

from terraform-aws-ec2-autoscale-group.

The module always deploys with the template version = 1. Even if launch_template has the latest version = 5

~ module.asg.aws_launch_template.default
      latest_version:                          "5" => "0"
      tag_specifications.0.tags.sourceCodeRef: "0ccb201" => "52e5bb1"

Terraform docs (With Latest Version Of Launch Template)

resource "aws_launch_template" "foobar" {
  name_prefix   = "foobar"
  image_id      = "ami-1a2b3c"
  instance_type = "t2.micro"
}

resource "aws_autoscaling_group" "bar" {
  availability_zones = ["us-east-1a"]
  desired_capacity   = 1
  max_size           = 1
  min_size           = 1

  launch_template {
    id      = "${aws_launch_template.foobar.id}"
    version = "$Latest"
  }
}

But in your module launch_template version is a reference to terraform resource - aws_launch_template.default.latest_version - https://github.com/cloudposse/terraform-aws-ec2-autoscale-group/blob/master/main.tf#L99. It looks right but does not work and does not comply with the Terraform documentation.

I think we can make a switch and use either the launch_template_version variable ("$Latest" or "$Default") - https://github.com/cloudposse/terraform-aws-ec2-autoscale-group/search?q=launch_template_version&unscoped_q=launch_template_version or use terraform resource reference such as aws_launch_template.default.latest_version
