Unable to use terraform-aws-modules/vpc/aws

[Mayank Kumar]

Hi,

I am getting below error when using the module in the resource file as:

module "vpc" {

  source = "terraform-aws-modules/vpc/aws"

  name = "Terraform"

  cidr = "10.0.0.0/16"

  azs = "${slice(data.aws_availability_zones.available.names,0,var.subnet_count)}"

  private_subnets = ["10.0.1.0/24", "10.0.3.0/24"]

  public_subnets = ["10.0.0.0/24", "10.0.2.0/24"]

  enable_nat_gateway = true

  create_database_subnet_group = false

  

  tags {

  }

}

When running init in the folder, i am receiving this issue:

C:\Users\terraform\project-03\>terraform init

Initializing modules...

- module.vpc

  Found version 2.1.0 of terraform-aws-modules/vpc/aws on registry.terraform.io

  Getting source "terraform-aws-modules/vpc/aws"

Error downloading modules: Error loading modules: module vpc: Error parsing .terraform\modules\2683148c87fd679d1116df9f

366f3b91\terraform-aws-modules-terraform-aws-vpc-c032c26\main.tf: At 2:23: Unknown token: 2:23 IDENT max

I can see in the module issue is coming at: 

locals {

  max_subnet_length = max(

    length(var.private_subnets),

    length(var.elasticache_subnets),

    length(var.database_subnets),

    length(var.redshift_subnets),

  )

Any pointers for this?

you need to pick a version... either to use a compatible with tf 0.11 or 0.12
