Configuring AWS provider

Before using Terraform to create an instance, we need to configure AWS provider. This is the first piece of code we will write in our template. Templates are written in a special language named HashiCorp Configuration Language (HCL). More details about HCL can be found at https://github.com/hashicorp/hcl. You can also write your templates in JSON, but this is recommended only if a template is itself generated or read by a machine.

We can configure credentials in the following ways.

Static credentials

With this method, you just hardcode your access keys right inside your template. It looks as follows:

    provider "aws" {
        access_key = "xxxxxxxxxxxxx"
        secret_key =...
