How to setup tag_specifications for launch template resource

[tkumark]

base on the documentation example given below I see the tag set for instance type. But If I want the same tag to be applied to multiple resources then how would I set it up
https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/launch_template

  tag_specifications {
    resource_type = "instance"

    tags = {
      Name = "test"
    }
  }

A documentation example can be added but for this specific issue:

  tag_specifications {
    resource_type = "instance"

    tags = {
      Name = "test"
    }
  }

  tag_specifications {
    resource_type = "volume"

    tags = {
      Name = "test"
    }
  }

can achieve this. to make this more DRY you can use https://www.terraform.io/docs/language/expressions/dynamic-blocks.html

• use the below example.

locals {
  tags_dest = ["instance", "volume", "elastic-gpu", "network-interface", "spot-instances-request"]
}

  dynamic "tag_specifications" {
    for_each = toset(local.tags_dest)
    content {
      resource_type = tag_specifications.key
      tags = {
          ENV = "dev"
           }
       }
    }

Be aware that aws will not be able to start a new instance (in the Autoscaling Group) if you specify a resource_type which you don't launch.

Launching a new EC2 instance. Status Reason: You cannot specify tags for elastic GPUs if there are no elastic GPUs being created by the request. Launching EC2 instance failed.

@mafeko this is strange.

if default tags are set on provider level, i expect that all resources will be tagged.... but i see why it don't happen.
