Expected Behavior

Expect the module to download and work.

Actual Behavior

Module load fails with:

Error loading Terraform: module api.root: 1 error(s) occurred:

* resource 'aws_security_group.api_host_sg' config: unknown resource 'aws_vpc.environment_api' referenced in variable aws_vpc.environment_api.cidr_block

Steps to Reproduce

1. terraform get -update

Oh goddamit. Variable naming. Should be:

data.aws_vpc.environment_api...

PEBCAK. Suspect this means some of the docs are wrong. Will look.
