An example of Terraform which brings up a VPC with Public/Private Subnets

terraform-aws-vpc

This repository contains a Terraform project that builds Scenario 2: VPC with Public and Private Subnets from the AWS documentation. It's from this blog post describing how it all works and is designed to give a working example which can the basis of something much more complex.

Usage

terraform.tfvars holds variables which should be overriden with valid ones.

Plan

terraform plan -var-file terraform.tfvars

Apply

terraform apply -var-file terraform.tfvars

Destroy

terraform destroy -var-file terraform.tfvars

Use

amend terraform.tfvars with own AWS access, secret, keyname

aws_access_key = "xxxx"
aws_secret_key = "xxxx"
aws_key_path = "~/.ssh/aws.pem"
aws_key_name = "xxxx"

amend public.tf - amend with own availability_zone eg. in ap-southeast-2a, subnet_id

resource "aws_instance" "web-1" {
availability_zone = "ap-southeast-2a"      
subnet_id = "${aws_subnet.ap-southeast-2a-public.id}"

amend private.tf - amend with own availability_zone eg. in ap-southeast-2a, subnet_id

resource "aws_instance" "db-1" {
availability_zone = "ap-southeast-2a"      
subnet_id = "${aws_subnet.ap-southeast-2a-public.id}"

amend variables.tf - amend with default aws_region, amis - image type eg. current ubuntu version

variable "aws_region" {
default = "ap-southeast-2"
variable "amis" {
ap-southeast-2 = "ami-47726224" # ubuntu 16.04 LTS

amend vpc.tf - amend as shown these a few below

resource "aws_instance" "nat" {
    ami = "ami-0154c73b" # this is a special ami preconfigured to do NAT Check under Images/AMI
    availability_zone = "ap-southeast-2a"
    subnet_id = "${aws_subnet.ap-southeast-2a-public.id}"

resource "aws_subnet" "ap-southeast-2a-public" {
    availability_zone = "ap-southeast-2a"
