How to get the default vpc id with terraform

Question

I am trying to get the vpc_id of default vpc in my aws account using terraform

This is what I tried but it gives an error

Error: Invalid data source

this is what I tried:

data "aws_default_vpc" "default" {

}


# vpc
resource "aws_vpc" "kubernetes-vpc" {
  cidr_block = "${var.vpc_cidr_block}"
  enable_dns_hostnames = true

  tags = {
    Name = "kubernetes-vpc"
  }
}

Answer 1

The aws_default_vpc is indeed not a valid data source. But the aws_vpc data source does have a boolean default you can use to choose the default vpc:

data "aws_vpc" "default" {
  default = true
}
