Variables topic
variables are values
use of variables: hide the values ( like clinet id, locatin secret id etc)
create two files in visual studio.
1 variables.tf
2.variables.tfvars
keep the information in variables.tfvars like example below
client_id= “dd098941-1b04-40c5-ac3e-221310d5c75a”
tenant_id= “4b6f90b2-12cc-45f0-8527-da31b2259cca”
subscription_id= “7b43c9f5-2b23-42c6-a7bf-d8e1cf4af406”
client_secret= “JEh8Q~Apkczpsk4iFXVzPDn-OWM.MjFW-6kiaaE9”
location = “eastus”
keep the names ( clientid,loaction. tenant id) in variables.tf
variable “client_id”{}
variable “tenant_id”{}
variable “subscription_id”{}
variable “client_secret” {}
variable “location” {}
then keep the variable names in the main.tf file example below
provider “azurerm” {
features{}
# Configuration options
client_id= var.client_id
tenant_id= var.tenant_id
subscription_id= var.subscription_id
client_secret= var.client_secret
}
resource “azurerm_resource_group” “Test1RG” {
name = “Test1”
location = var.location
}
execuete command
terraform apply –var-file variables.tfvars
count is name
length is function
length(var.location)=== function
