I'm getting confused when using Terraform to provision an auto-scaling group. Should I use launch configuration or launch template for EC2 properties, such as which AMI, instance types, ...?
I don't know what the difference is between them, which we should use and why they exist?
| Launch templates (LTs) are newer than launch configurations (LCs) and provide more options to work with. Thus, the AWS documentation recommends use of launch templates (LTs) over launch configuration (LCs):

I want to attach multiple IAM Policy ARNs to a single IAM Role.

First off - apologies - I’m extremely new (3 hours in!) to using terraform.
I am looking to try and use the value of a variable inside the declaration of another variable.

What is the least painful way to migrate state of resources from one project (i.e., move a module invocation) to another, particularly when using remote state storage?
