Terraform Cloud/Enterprise

The environment variables mentioned in this page can also be set in an Infracost config file.

Terraform Cloud users#

This section is only applicable for Terraform Cloud users.

Running Infracost locally requires no additional steps as your Terraform CLI config file is used to access the plan.

When running Infracost on CI/CD systems, you should either:

  1. Set the INFRACOST_TERRAFORM_CLOUD_TOKEN environment variable to a Team API Token or User API Token.
  2. Set the Terraform environment variable TF_CLI_CONFIG_FILE to the absolute path of your Terraform CLI config file.

Terraform Enterprise users#

When running Infracost locally or on CI/CD systems, you should set both of the following environment variables:

  1. INFRACOST_TERRAFORM_CLOUD_TOKEN to a Team API Token or User API Token.
  2. INFRACOST_TERRAFORM_CLOUD_HOST to your backend host, this overrides the default app.terraform.io value.

Terraform workspaces#

If you use multiple Terraform workspaces, use an Infracost config file to define them; their results will be combined into the same breakdown or diff output.

If you'd like to select one workspace, you can do so by either:

  1. using the --terraform-workspace flag.
  2. setting the INFRACOST_TERRAFORM_WORKSPACE environment variable (this sets the TF_WORKSPACE internally).

Only set this for multi-workspace deployments, otherwise it might result in the Terraform error "workspaces not supported". If you see this error, try running unset INFRACOST_TERRAFORM_WORKSPACE and unset TF_WORKSPACE.
