[D1] Terraform to AWS

This issue will include an overview of how I created an AWS account and the Terraform configuration used to provision an AWS EC2 instance.

Resources

• Get Started - AWS
• Install or update the latest version of the AWS CLI
• AWS Free Tier
• What is IAM Identity Center?
• Managing access keys for IAM users

[emilyllim]

Set up directory to store Terraform files

• mkdir terraform
• cd terraform

Install the AWS CLI

• curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
• unzip awscliv2.zip
• sudo ./aws/install
• aws --version

Prepare an AWS account for provisioning resources

• Create an AWS Free Tier account
• Using the root user, enable the IAM Identity Center
• Create an AWS organization
• Create an admin user by creating a new user and adding an administrative permission set
• Using the admin user, create an IAM user with power user access
• Create an access key for the new IAM user

Create the Terraform configuration

• Use security credentials of that account to authenticate and authorize any requests
  • export AWS_ACCESS_KEY_ID=[ACCESS KEY ID VALUE]
  • export AWS_SECRET_ACCESS_KEY=[SECRET ACCESS KEY VALUE]
• vi main.tf - create and edit the configuration file to define the EC2 instance

Use Terraform to provision the instance

• terraform init - initialize the directory, and download and install the defined providers
• terraform apply - review the execution plan and then type yes to apply the configuration
• The EC2 instance should be running and available to view on the AWS console

Destroy the instance

• terraform destroy
