AWS Networking Template

This module provisions essential network components of AWS.

The resulting resources include

• A VPC
• Public subnets (arbitrary numbers)
• Private subnets (arbitrary numbers)
• Route tables
• An internet gateway, if needed
• A NAT gateway and the associated Elastic IP, if needed
• Security groups

Usage Example

# in `main.tf`
module "network" {
source = "github.com/uniglot/aws-networking-template"

project_name = "module-test"
vpc_cidr = "10.0.1.0/24"
pub_sub_cidrs = ["10.0.1.0/25"]
pri_sub_cidrs = ["10.0.1.128/25"]
ssh_allowed_cidrs = ["123.123.12.3/32"]
}
