What is terraform.tfvars?

Terraform .tfvars files are used to store variable definitions. This allows you to externalize your variable definitions and makes it easier to manage them, especially if you have a large number of variables or need to use the same variables in multiple environments.

Terraform automatically loads all files in the current directory with the exact name terraform.tfvars or matching *.auto.tfvars. You can also use the -var-file flag to specify other files by name.

.tfvars files use syntax similar to Terraform configuration files (HCL), but they cannot contain configuration such as resource definitions. Like Terraform configuration files, .tfvars files can also contain JSON.
