Files and Directories - Configuration Language - Terraform

Terraform evaluates all of the configuration files in a module, effectively treating the entire module as a single document. Separating various blocks into different files is purely for the convenience of readers and maintainers, and has no effect on the module's behavior. A Terraform module can use module calls to explicitly include other modules into the configuration. These child modules can come from local directories (nested in the parent module's directory, or anywhere else on disk. When you want to create the infrastructure with the Terraform, the Terraform Configuration file (HCL) should be executed with the help of Terraform CLI or other executors. The most popular and convenient way is Terraform CLI. So, this article will mainly focus on the Terraform Configuration language of the configuration Files The terraform-docs configuration is a yaml file. This is a convenient way to share the configuation amongst teammates, CI, or other toolings. To do so you can use -c or --config flag which accepts name of the config file File: A configuration file may be specified via the init command line. To specify a file, use the -backend-config=PATH option when running terraform init. If the file contains secrets it may be kept in a secure data store, such as Vault, in which case it must be downloaded to the local disk before running Terraform A Terraform configuration is a complete document in the Terraform language that tells Terraform how to manage a given collection of infrastructure.
