The purpose of this module is to deploy EC2 instance in AWS, using Terraform AWS provider

The module is using AWS provider version 4.63.0. It contains four blocks:

• terraform - block is needed to ensure that correct plugin version is downloaded.
• data.aws_ami.ubuntu - block is used to get list of AMI IDs in specific region (see requirements how to set region) and to filter results by name: *ubuntu-jammy-22.04-amd64-server- **
• data.aws_key_pair.search_for_key_pair - block is used to get list of previously stored key pairs in specific region (see requirements how to set region) in order to create EC2 with existing keypair to enable future login options.
• resource.aws_instance.VM - block is creating EC2 instance with mentioned above parameters and with type t2.micro.

To ensure proper authentication with AWS and location on EC2, module expects following environment variables to be defined:

• AWS_ACCESS_KEY
• AWS_SECRET_ACCESS_KEY
• AWS_REGION / AWS_DEFAULT_REGION

If you are using localy Terraform open source on MAC/Linux platform or with Terraform Cloud CLI-driven run you can achieve this by

1. Run following commands in terminal:

export AWS_ACCESS_KEY=<your_AWS_access_key>
export AWS_SECRET_ACCESS_KEY=<your_AWS_secret_access_key>
export AWS_REGION=<your_AWS_region>

You can verify that variable are set when you run command export in same terminal.

2. Create variable set (only for Terraform Cloud runs) Please find detailed guide how to do it here.

3. Add credential details directly in provider configuration block (highly not recommended)

provider "aws" {
  region = "<your_region>"
  access_key = "<your_AWS_access_key>"
  secret_key = "<your_AWS_secret_access_key>"
}

Module can be used in any terraform configuration files with the following example:

module "EC2_instance" {
source = "github.com/IvanGavrilov777/terraform-aws-ec2_instance"
}

In case if you want to use this module in CLI-driven run in Terraform Cloud, you should add cloud {} block in your terraform block:

terraform {
  cloud {
    organization = "<name_of_your_organization>"
    workspaces {
      name = "<name_of_your_workspace>"
    }
  }
}
