Required Input Variables

At least following input variables must be provided. See full list of supported variables

Name	Description
name	Common name, a unique identifier

Usage

To provision default configuration containing one private and one public subnet in each availability zone use:

module "network" {
  source = "./modules/aws_network"
  name   = "Example Project"
}

By default vpc flow log is turned off as it applies additional charge. To turn it on add "vpc_flow_log_enabled" property:

module "network" {
  source = "./modules/aws_network"
  name   = "Example Project"

  vpc_flow_log_enabled = true
}

If any alterations to subnets required, use "subnets" parameter to specify custom configuration:

module "network" {
  source = "./modules/aws_network"
  name   = "Example Project"
  
  subnets = [
    {
      name        = "public"
      ig_attached = true
      tags        = {
        kubernetes.io/cluster/eks-cluster = "shared",
        kubernetes.io/role/elb            = "1"
      }
    },
    {
      name        = "eks"
      ig_attached = false
      tags        = {
        kubernetes.io/cluster/eks-cluster = "shared",
        kubernetes.io/role/internal-elb   = "1"
      }
    }
  ]
}
