Windows users:

  1. Go to https://www.terraform.io/downloads.html
  2. Press 64-bit:
  3. Extract the zip file (you just downloaded).
  4. Move terraform.exe file to C:\Windows\System32

Open a CMD / Terminal and run:

terraform –v

Any response other than “terraform is not recognized” is good

AWS Configuration

Login as Yakikim2

Lunch instance at EC2

Define user at IAM

you should define user with the proper credentials as well as "AWS Identity and Access Management" credential.

!Pasted image 20210419101516.png
then you will generate and backup the access+secret key at the "Security credentials" tab

Generate the SSH Key pair

At EC2 you should create a "Key pair" that latly you will use it in VNC tool like Putty

Edis the file https://github.com/Dgotlieb/SimpleTerraform/blob/main/main.tf

finally it looks (In MY case) as:

provider "aws" {
  region = "us-west-2"
  access_key = "AKIA3H4ALTA4AI57N7OC"
  secret_key = "P8ajJLaMkleVB4hs7UOzd5Cnssu5SievRVhtoLzp"

resource "aws_instance" "example" {
  ami           = "ami-02701bcdc5509e57b"
  key_name		= "custom_key"
  instance_type = "t2.micro"
  vpc_security_group_ids = ["${aws_security_group.instance.id}"]
  user_data = <<-EOF
              sudo apt update
              yes | sudo apt install nginx
  tags = {
    Name = "terraform-example"

resource "aws_security_group" "instance" {
  name = "terraform-example-instance"
  ingress {
    from_port   = 80
    to_port     = 80
    protocol    = "tcp"
    cidr_blocks = [""]
  ingress {
    from_port   = 22
    to_port     = 22
    protocol    = "tcp"
    cidr_blocks = [""]
  egress {
    from_port   = 0
    to_port     = 0
    protocol    = "-1"
    cidr_blocks = [""]

# Add Output
output "public_ip" {
  value       = "aws_instance.example.public_ip"
  description = "The public IP of the web server"

Terraform Init and apply

terraform init

terraform plan

terraform apply

Then type 'yes' and the instances will be created.
when we wnat to use the IP for the SSH connection, we can send the command

terraform destroy

and the IP will be displayd (DONT approve the destroy..)

About Terraform



Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. Terraform can manage existing and popular service providers as well as custom in-house solutions.

The key features of Terraform are:

  • Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.

  • Execution Plans: Terraform has a "planning" step where it generates an execution plan. The execution plan shows what Terraform will do when you call apply. This lets you avoid any surprises when Terraform manipulates infrastructure.

  • Resource Graph: Terraform builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, Terraform builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.

  • Change Automation: Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what Terraform will change and in what order, avoiding many possible human errors.

For more information, see the introduction section of the Terraform website.

Getting Started & Documentation

Documentation is available on the Terraform website:

If you're new to Terraform and want to get started creating infrastructure, please check out our Getting Started guides on HashiCorp's learning platform. There are also additional guides to continue your learning.

Show off your Terraform knowledge by passing a certification exam. Visit the certification page for information about exams and find study materials on HashiCorp's learning platform.

Developing Terraform

This repository contains only Terraform core, which includes the command line interface and the main graph engine. Providers are implemented as plugins, and Terraform can automatically download providers that are published on the Terraform Registry. HashiCorp develops some providers, and others are developed by other organizations. For more information, see Extending Terraform.

To learn more about compiling Terraform and contributing suggested changes, please refer to the contributing guide.

To learn more about how we handle bug reports, please read the bug triage guide.
