The file provisioner is a built-in Terraform feature designed for exactly this purpose. This tutorial will explain what the file provisioner is, how to use it, and—most importantly—its limitations and modern alternatives.

source: The path to the file or directory on your local machine where you are running Terraform.
destination: The absolute path on the remote machine where the file or directory should be placed.
connection: The block that tells Terraform how to connect to the newly created resource, typically using SSH for Linux or WinRM for Windows.
We will provide a practical example showing how to upload a simple shell script (script.sh) to an EC2 instance. This will clearly demonstrate the syntax and how the provisioner executes during the terraform apply process, specifically after the resource is created.
However, a crucial part of this tutorial is understanding HashiCorp's official recommendation: provisioners should be a last resort. We will dedicate a section to explaining why this is the case. We'l
