Terraform Installation and Configuration with AWS Cloud: A Complete Example

Terraform is an open-source infrastructure as code software tool that allows you to define and provision infrastructure resources in a safe and repeatable way. In this tutorial, we will guide you on how to install and configure Terraform with AWS Cloud and provide a complete example.

Prerequisites

Before we begin, make sure that you have the following installed on your machine:

• AWS CLI

Installing Terraform

To install Terraform, follow these steps:

1. Open a terminal window and run the following command to download the latest version of Terraform:

curl -O https://releases.hashicorp.com/terraform/1.0.5/terraform_1.0.5_linux_amd64.zip

2. Run the following command to extract the downloaded file:

unzip terraform_1.0.5_linux_amd64.zip

3. Run the following command to move the Terraform binary to the /usr/local/bin directory:

sudo mv terraform /usr/local/bin/

4. Run the following command to verify that Terraform has been installed:

terraform --version

Configuring AWS Credentials

To configure AWS credentials for Terraform, follow these steps:

1. Open a terminal window and run the following command:

aws configure

2. Enter your AWS access key ID and secret access key when prompted.
3. Enter the default region name and output format when prompted.

Creating a Terraform Configuration

Once you have installed and configured Terraform with AWS Cloud, you can create a Terraform configuration using the following steps:

1. Create a new directory for your Terraform configuration.
2. Create a new file named main.tf in the directory.
3. Add the following code to the main.tf file:

provider "aws" {  region = "us-west-2"}resource "aws_instance" "example" {  ami           = "ami-0c55b159cbfafe1f0"  instance_type = "t2.micro"}

In this example, we are using the aws_instance resource to create a new EC2 instance with the t2.micro instance type and the ami-0c55b159cbfafe1f0 Amazon Machine Image (AMI).

4. Save the main.tf file.

Initializing and Applying the Terraform Configuration

Once you have created your Terraform configuration, you can initialize and apply it using the following steps:

1. Open a terminal window and navigate to the directory where your main.tf file is located.
2. Run the following command to initialize Terraform:

terraform init

3. Run the following command to apply your Terraform configuration:

terraform apply

4. When prompted, review the changes that Terraform will make to your infrastructure and type yes to apply the changes.
5. Wait for Terraform to provision the new EC2 instance.

Conclusion

Congratulations! You have successfully installed and configured Terraform with AWS Cloud and created a new EC2 instance using a Terraform configuration. You can now use Terraform to define and provision infrastructure resources in a safe and repeatable way.
