Terraform Variables prompting me when defined in tfvars - variables

Question

There is something that I am not understanding about terraform variables. I am getting prompted for two variables in when I run "terraform apply". I don't think that I should be prompted for any as I defined a terraform.tfvars. I am getting prompted for (applicationNamespace, and staticIpName) but I am not sure why. What am I misunderstanding?
I created a file (terraform.tfvars):
#--------------------------------------------------------------
# General
#--------------------------------------------------------------
cluster = "reddiyo-development"
project = "<MYPROJECTID>"
region = "us-central1"
credentialsLocation = "<MYCERTLOCATION>"
bucket = "reddiyo-terraform-state"
vpcLocation = "us-central1-b"
network = "default"
staticIpName = "dev-env-ip"
#--------------------------------------------------------------
# Specific To NODE
#--------------------------------------------------------------
terraformPrefix = "development"
mainNodeName = "primary-pool"
nodeMachineType = "n1-standard-1"
#--------------------------------------------------------------
# Specific To Application
#--------------------------------------------------------------
applicationNamespace = "application"
I also have a terrform script:
variable "cluster" {}
variable "project" {}
variable "region" {}
variable "bucket" {}
variable "terraformPrefix" {}
variable "mainNodeName" {}
variable "vpcLocation" {}
variable "nodeMachineType" {}
variable "credentialsLocation" {}
variable "network" {}
variable "applicationNamespace" {}
variable "staticIpName" {}
data "terraform_remote_state" "remote" {
backend = "gcs"
config = {
bucket = "${var.bucket}"
prefix = "${var.terraformPrefix}"
}
}
provider "google" {
//This needs to be updated to wherever you put your credentials
credentials = "${file("${var.credentialsLocation}")}"
project = "${var.project}"
region = "${var.region}"
}
resource "google_container_cluster" "gke-cluster" {
name = "${var.cluster}"
network = "${var.network}"
location = "${var.vpcLocation}"
remove_default_node_pool = true
# node_pool {
# name = "${var.mainNodeName}"
# }
node_locations = [
"us-central1-a",
"us-central1-f"
]
//Get your credentials for the newly created cluster so that microservices can be deployed
provisioner "local-exec" {
command = "gcloud config set project ${var.project}"
}
provisioner "local-exec" {
command = "gcloud container clusters get-credentials ${var.cluster} --zone ${var.vpcLocation}"
}
}
resource "google_container_node_pool" "primary_pool" {
name = "${var.mainNodeName}"
cluster = "${var.cluster}"
location = "${var.vpcLocation}"
node_count = "2"
node_config {
machine_type = "${var.nodeMachineType}"
oauth_scopes = [
"https://www.googleapis.com/auth/logging.write",
"https://www.googleapis.com/auth/monitoring",
"https://www.googleapis.com/auth/devstorage.read_only",
"https://www.googleapis.com/auth/service.management.readonly",
"https://www.googleapis.com/auth/servicecontrol",
"https://www.googleapis.com/auth/trace.append",
]
}
management {
auto_repair = true
auto_upgrade = true
}
autoscaling {
min_node_count = 2
max_node_count = 10
}
}
# //Reserve a Static IP
resource "google_compute_address" "ip_address" {
name = "${var.staticIpName}"
}
//Install Ambassador
module "ambassador" {
source = "modules/ambassador"
applicationNamespace = "${var.applicationNamespace}"
}

Answer 1

You can try to force it to read your variables by using:
terraform apply -var-file=<path_to_your_vars>

Answer 2

For reference, read below, if anybody face the similar issue.
“terraform.tfvars” is the default variable file name, from where terraform will read variables.
If any other file name is used, it needs to be passed in the command line i.e: “terraform plan –var=whateverName.tfvars
Also, order of Loading for variables by Terraform program.
Environment Variables
terraform.tfvars
terraform.tfvars.json
Any .auto.tfvars
Any –var or –var-file options
