I have created one terraform code for creating vpc, subnets, nat gateway and internet gateway. When i trying to run its thrown error like below
Error: Reference to undeclared resource
on create-vpc.tf line 77, in resource "aws_subnet" "public-subnet-1":
77: vpc_id = "${aws_vpc.production-vpc.id}"
A managed resource "aws_vpc" "production-vpc" has not been declared in the
root module.
I have pasted my terraform code. Kindly valid it
provider"aws" {
access_key="xxxxxxxx"
secret_key="yyyyyyyy"
region="us-east-1"
}

##I have separate file for subnet cidr values named prod-vpc-cidr.tfvars
I can terraform init
when i run #terraform plan -var-file="prod-vpc-cidr.tfvars"
