Exception:
Error: Reference to undeclared resource
on base.tf line 65, in resource "aws_subnet" "public-subnet-a":
65: availability_zone = "${data.aws_availability_zones.available.names[0]}"
A data resource "aws_availability_zones" "available" has not been declared in
the root module.
Explanation:
The exception occurred while assigning the availability zone for a region in the terraform template.
resource "aws_subnet" "public-subnet-a" {
vpc_id = "${aws_vpc.vpc.id}"
map_public_ip_on_launch = true
cidr_block = "10.0.10.0/24"
availability_zone = "${data.aws_availability_zones.available.names[0]}"
tags = {
Name = "public-subnet-a:${var.labname}"
}
}
Solution:
Add data module to get the availability zones for a region
data "aws_availability_zones" "available" {}
resource "aws_subnet" "public-subnet-a" {
vpc_id = "${aws_vpc.vpc.id}"
map_public_ip_on_launch = true
cidr_block = "10.0.10.0/24"
availability_zone = "${data.aws_availability_zones.available.names[0]}"
tags = {
Name = "public-subnet-a:${var.labname}"
}
}
