# Terraform config for creating VPC and subnets

These config will create the following resources on AWS. The VPC CIDR is hard-coded as 10.0.0.0/16. The subnets will sit in different availablity zones for redundancy. Resources are all tagged from a globaltag list.

* 1 VPC
* public subnets in all AZs
* private subnets in all AZs
* 1 internet gateway
* 1 nat gateway

## Variables to TF
These are required variables:

```
aws_access_key = "redacted"
aws_secret_key = "redacted"
aws_region = "ap-southeast-1"
resource_prefix = "project1-dev"
```

## Revision notes
* Previously terraform plan would fail to compute the count for routing table association. This is now corrected by setting count = number of AZs
