Terraform AWS Learning

This repo is a basic example of how to create an AWS EC2 instance through IaC.

To create the resource use the following commands:

1. terraform init: Generates the necessary files for Terraform to execute.
2. terraform plan: Shows the changes that will be made (This requires the AWS CLI to be configured correctly).
3. terraform apply: Executes the changes done to the AWS Resources.

After all that is done, a terraform.tfstate file will be created. This file contains the current state of the infraestructure. This file should not be maintained locally.

1. terraform destroy: Removes everything that is currently mapped in the terraform.tfstate file.
