vadim-hleif and osterman Add example usage (#21)
* feat(examples): add basic example

* Update namespace description in basic example

* Create cidr_block variable in basic example

Use it in both modules

* Move default values from variables.tf to terraform.tfvars

- set subnets nat_gateway_enabled as false
- check on geodesic

* Rename tfvars file

Terraform module to provision a VPC with Internet Gateway.


This project is part of our comprehensive "SweetOps" approach towards DevOps.

Terraform Open Source Modules

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Examples

module "vpc" {
  source    = "git::https://github.com/cloudposse/terraform-aws-vpc.git?ref=master"
  namespace = "cp"
  stage     = "prod"
  name      = "app"
}

Full example with terraform-aws-dynamic-subnets:

module "vpc" {
  source    = "git::https://github.com/cloudposse/terraform-aws-vpc.git?ref=master"
  namespace = "cp"
  stage     = "prod"
  name      = "app"
}

module "dynamic_subnets" {
  source             = "git::https://github.com/cloudposse/terraform-aws-dynamic-subnets.git?ref=master"
  namespace          = "cp"
  stage              = "prod"
  name               = "app"
  region             = "us-west-2"
  availability_zones = ["us-west-2a","us-west-2b","us-west-2c"]
  vpc_id             = "${module.vpc.vpc_id}"
  igw_id             = "${module.vpc.igw_id}"
  cidr_block         = "10.0.0.0/16"
}
