Demo VPC, IGW, Public & Private Subnets

This repository creates a VPC, IGW, public and private subnets and route tables.

Architecture

The following will be created:

Configuring S3 Backend

This project can be configured to use S3 as a backend to store the state file. In addition a DynamoDB locks table will be created.

To enable S3 first set the varible backend_enabled to true. Then run a terraform innit and terraform apply. Once applied you can now change versions.tf and enable backend support.

terraform {
   backend "s3" {
     bucket         = "ENTER_BUCKET_NAME"
     key            = "terraform_vpc/terraform.tfstate"
     region         = "eu-west-1"
     encrypt        = true
     kms_key_id     = "ENTER_KMS_ID"
     dynamodb_table = "ENTER_DYNAMODB_TABLE_NAME"
   }
   // other terraform configuration
}

These values can be gathered from the outputs from the terraform apply.
