cloudposse/terraform-aws-dynamic-subnets 0.9.0

0.9.0 Add `nat-instance`

on GitHub

what

• Add nat-instance
• Correctly pin terraform required_version

why

• Allow users to choose between NAT Gateways or NAT Instances to be deployed into the public subnets to allow the servers in the private subnets to access the Internet
• In many cases, NAT Instances are cheaper than NAT Gateways, and for some use-cases (e.g. testing/demo infrastructure) are more appropriate to use (e.g. save on cost)
• Pin terraform required_version to 0.11.x only (the module does not support TF 0.12
