terraform.tfvars¶
terraform.tfvarsserves as a way to store variable values for your infrastructure configuration.it contains variable names and their corresponding values, separated by an equals sign (
=).
why we need terraform.tfvars¶
Purpose: separate variable definitions from Terraform code. This promotes code reusability and makes it easier to manage different environments with different variable values.
Benefits:
- Flexibility: You can easily change variable values by modifying the
terraform.tfvarsfile, without altering your Terraform code. - Security: Sensitive information like API keys or passwords can be kept out of your main Terraform code, potentially enhancing security.
- Environment-specific configurations: You can create multiple
terraform.tfvarsfiles for different environments (e.g., development, staging, production), each with its own set of variable values.
- Flexibility: You can easily change variable values by modifying the
Usage: Terraform automatically loads variables defined in
terraform.tfvarswhen you run commands liketerraform apply. You can also specify additionaltfvarsfiles using the-var-fileflag.
Note that the terraform.tfvars file is not mandatory. We can pass variable values in various ways, such as through command-line flags, environment variables, or interactive prompts.
