Init Environment

We will set up necessary environmental variables for Terraform. With variable block, this is global variable that you can use it in anywhere in Terraform.

Terraform will load all files *.tf format in root module, so you can name the file whichever you want. Now, we will create tf-variables.tf file with all content in this page:

Init Terraform configuration

Specifying version to run. This workshop uses:

• Terraform version: required_version = "1.9.6".
• Provider AWS: hashicorp/aws version = "5.70.0".
• Template: hashicorp/template = "2.2.0".

terraform {
  required_providers {
    aws = {
      source = "hashicorp/aws"
      version = "5.70.0"
    }
    template = {
      source = "hashicorp/template"
      version = "2.2.0"
    }
  }
  required_version = "1.9.6"
}

Init Account

We have some security credentials in previous step. We need to load it into Terraform:

# AWS Account
variable "access_key" {}
variable "secret_key" {}

Init Provider and Region

I choose the region Singapore. You can change it if you want:

provider "aws" {
    secret_key = var.secret_key
    access_key = var.access_key
    region = "ap-southeast-1"  # Singapore
}

Init Data resources

Config data resources to get aws value when applying

# Get current Account ID
data "aws_caller_identity" "current" {}

# Get current region
data "aws_region" "current" {}

# Get current availability zones of region
data "aws_availability_zones" "available" {}

Finally, we completely set up necessary variables and environment for Terraform. Please save it and go to next step.
