AWS Cloud VPC Subnet module

Provisions public and private subnet for VPC. The full list of resources provisioned is as follows:

• Can create a Single zone or multi-zone subnets. By default mutlizone subnets are created.
• Create a Public Subnet by attaching Internet Gateway
• Create a Private Subnet by attaching Nat Gateway

Description

Description of module

Note: This module follows the Terraform conventions regarding how provider configuration is defined within the Terraform template and passed into the module - https://www.terraform.io/docs/language/modules/develop/providers.html. The default provider configuration flows through to the module. If different configuration is required for a module, it can be explicitly passed in the providers block of the module - https://www.terraform.io/docs/language/modules/develop/providers.html#passing-providers-explicitly.

Software dependencies

The module depends on the following software components:

Command-line tools

• terraform >= v0.15

Terraform providers

• AWS Cloud provider ~> 3.0

Module dependencies

This module makes use of the output from other modules:

• terraform-aws-vpc module https://github.com/cloud-native-toolkit/terraform-aws-vpc

Also has optional dependencies on the following modules in case Internet Gateway or Nat Gateway is attached to VPC /Subnet

• terraform-aws-vpc-gateways module github.com/cloud-native-toolkit/terraform-aws-vpc-gateways
• terraform-aws-nat-gateway module github.com/cloud-native-toolkit/terraform-aws-nat-gateway

Example usage

The following will create a multizone subnet. To create subnets in single zone, set multi-zone to false

• To create a public subnet with internet gateway attached, make sure to set label as 'public' and proivde the internet gateway ID

• To create a private subnet, make sure to set label as 'private' and in case to attach Nat Gateway, proivde the nat gateway ID
