Terraform Input Variables using terraform.tfvars
Step-01: Introduction
- Provide Input Variables using
terraform.tfvars files
- Create a file named
terraform.tfvars and define variables
- If the file name is
terraform.tfvars, terraform will auto-load the variables present in this file by overriding the default values in c2-variables.tf
business_unit = "it"
environment = "stg"
resoure_group_name = "rg-tfvars"
resoure_group_location = "eastus2"
virtual_network_name = "vnet-tfvars"
subnet_name = "subnet-tfvars"
# Initialize Terraform
terraform init
# Validate Terraform configuration files
terraform validate
# Format Terraform configuration files
terraform fmt
# Review the terraform plan
terraform plan
# Create Resources
terraform apply
# Verify Resources
1. Resource Group Name
2. Resource Group Location
3. Virtual Network Name
4. Virtual Network Subnet Name
5. Compare with names present in c2-variables.tf to reconfirm it has overrided it and took from terraform.tfvars
Step-04: Clean-Up Files
# Destroy Resources
terraform destroy -auto-approve
# Delete Files
rm -rf .terraform*
rm -rf terraform.tfstate*
