Terraform POC

Terraform - Infrastructure as Code boilerplate for AWS as cloud service provider

This code builds an AWS infrastructure having:

• 1 IAM role for executing Lambda Functions

• 2 EC2 t2.micro instances

• 1 AWS Dynamo DB table titled 'TerraGameScores_v1' having 3 attributes and a global secondry index

• Uploads a set of Lambda Functions defined in zip file 'lambda_function_payload'

Getting Started

1. Update provider details in example.tf file with your AWS credentials:

provider "aws" {
  region     = "us-east-1"
  access_key = "ACCESS_KEY_HERE"
  secret_key = "SECRET_KEY_HERE"
}

2. Execute following commands to plan and deploy resources

terraform init
terraform plan
terraform apply // warning: this step will allocate AWS resources and may incur cost 

Deployment

Use following commands to better understand the state of the cloud infrastructure. Commands to be executed in format: terraform init

Initial planning and deployment commands:

    init               Initialize a new or existing Terraform configuration
    plan               Generate and show an execution plan
    apply              Builds or changes infrastructure

Terraform state management commands:

    destroy            Destroy Terraform-managed infrastructure
    output             Read an output from a state file
    providers          Prints a tree of the providers used in the configuration
    push               Upload this Terraform module to Terraform Enterprise to run
    refresh            Update local state file against real resources
    show               Inspect Terraform state or plan
    validate           Validates the Terraform files
    version            Prints the Terraform version
