Version

Help

terraform --help
terraform <command> --help

Initialization

The initialization operation initializes various local settings that will be used by subsequent commands. The command also downloads provider binaries. The command needs to be re-run if new modules are set or changed, or backend configuration changes.

terraform init

The command creates a .terraform directory, which contains a "plugins" sub-directory.

Configuration File Formatting

terraform fmt

Formats all .tf in the current directory. Formatting enables standardization.

Apply

terraform apply

provider.aws.region
  The region where AWS operations will take place. Examples
  are us-east-1, us-west-2, etc.

  Enter a value: us-west-2
