# 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.

installation and security features.

|
- Several [environment variables](/docs/cli/config/environment-variables.html) can
|
2020-10-27 02:15:36 +01:00
|
|
|
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.
