Tag EBS volume created by a launch_template and autoscaling group via Terraform

Question

How do we make the launch_template resource created by terraform, add tags to the EBS volume created and which is attached to the used AMI ?

Answer 1

Use tag_specifications with resource_type of volume.

resource "aws_launch_template" "foo" {
  name = "foo"

  block_device_mappings {
    device_name = "/dev/sda1"

    ebs {
      volume_size = 20
    }
  }

  image_id = "ami-test"
  instance_type = "t2.micro"
  key_name = "test"

  tag_specifications {
    resource_type = "instance"

    tags = {
      Name = "test"
    }
  }

  tag_specifications {
    resource_type = "volume"

    tags = {
      Name = "test"
    }
  }
}
