CLI Configuration

Terraform CLI can be configured with some global settings, which are separate from any Terraform configuration and which apply across all working directories.

We've designed Terraform such that an average user running Terraform CLI interactively will not need to interact with any of these settings. As a result, most of the global settings relate to advanced or automated workflows, or unusual environmental conditions like running Terraform on an airgapped instance.

• The CLI config file configures provider installation and security features.
• Several environment variables can configure Terraform's inputs and outputs; this includes some alternate ways to provide information that is usually passed on the command line or read from the state of the shell.
