Terratest your Terraform (Plans)
  [draft]

Problem statement As an infrastructure engineer writing Terraform, I’d like to test code before I apply it. Some constraints: I’d like this to work with Terraform Cloud and workspaces.

Neat & Secure: Adding AWS SQS to a Laravel 5.6 Application Y’know sometime when you’re working on an old codebase? and you wanna do something “new” but the docs don’t really help you much? Yeah? That’s what I’m documenting here. So I’m working on getting a Laravel 5.6 application into AWS Fargate with Terraform.
