Managing Ubuntu EC2 Developer Environment using Terraform

Managing Ubuntu EC2 Developer Environment using Terraform


I made an IAM user through my Root account in AWS. In addition, I stored the credentials in aws-vault which helps to execute commands faster and user-specific. Then, I installed Docker and Terraform in my local system Finally, deployed an EC2 using Terraform

Use Case

  • Provides Developer Friendly Environment
  • SSH access from desktop terminal
  • Infrastructure Provisioning

Cloud Research

[STEP - 1 --> IAM and AWS-Vault Setup]

  • Searched for "IAM" in AWS dashboard
  • Setup MFA (Multi Factor Authentication) for root user [Mandatory]

    • Downloaded Google Authenticator app from playstore in my Android Device
    • Signed in with the details provided by AWS MFA portal
    • Clicked on Reveal Pin to get Token (refreshes every 30 second)

    • Create User

    • Added permissions (existing policies) • AmazonEC2FullAccess
  • Displays the Credentials (Download the .csv file or copy and store the credentials in a safe location, This is will not be displayed again)

  • Incase you forgot to store the credentials, you need to create Access Key again and delete the previous one (Maximum limit of Access Key is 2)


  • Setting Credentials using AWS-Vault :
aws-vault add [user-id]
  • Asks for access_key_id and secret_access_key
  • Copy and paste the credentials of the IAM user created
  • Checks if the Credentials are stored correctly (Display Details of the Profile)
aws sts get-caller-identity
  • You can also list the users and store more credentials with different user-id
aws-vault list             --> (Lists user)
aws-vault add [user-id]    --> (Adds more user)

[STEP - 2 --> SSH Key and AWS Config]

  • Check if SSH Key already exists in your local machine using the following Command :
    cat ~/.ssh/
  • Copy the Key Content

    If its not found, go to the same location and Generate SSH Key using the following Command :

    ssh-keygen -t rsa
  • Open EC2 in AWS Dashboard and Click on Key Pairs
  • Go to Actions and then Import Key Pair
  • Name the key with anything you want (Please remember this Key Name, it will be needed later while using Terraform)
  • Paste the Key Content as done below :


  • Now, setup the AWS Config file using the following Command :
    vi ~/.aws/config
  • Enter the region and mfa_serial (Check the IAM user details in AWS Dashboard) under the user created by aws-vault like this :
    [profile ronitblenz]

[STEP - 3 --> Creating Docker Compose and Terraform Files]

  • Create a docker-compose.yaml file and paste the following snippet :

    version: '3.7'
     image: hashicorp/terraform:0.12.24
       - .:/infra
     working_dir: /infra
  • Create a file and paste the following snippet :

    provider "aws" {
    region  = "us-east-1"
    version = "~> 2.61.0"
    resource "aws_instance" "web" {
    ami           = "ami-052efd3df9dad4825"
    instance_type = "t2.micro"
    key_name      = "finalkey"
    security_groups = []
    tags = {
     Name = "WebServerByTf"
    resource "aws_security_group" "web" {
    name        = "web-security-group"
    description = "Allow access to our web server"
    ingress {
     description = "Allow SSH"
     from_port   = 22
     to_port     = 22
     protocol    = "tcp"
     cidr_blocks = [""]
    output "instance_public_dns" {
    value = aws_instance.web.public_dns
  • Turn on the Docker Daemon in Background (Else, the following commands will not be executed)

    • Initiate the Terraform Build

      docker-compose run --rm tf init
    • Shows the Tasks which are about to happen if the Terraform build is executed

      docker-compose run --rm tf plan
    • Execute the Terraform Build

      docker-compose run --rm tf apply
  • Type "yes" if asks for confirmation

    And, you have successfully created an EC2 Ubuntu instance over AWS using Terraform This can be used as a Testing Environment by Developers or Cloud Engineers.
