# Terragrunt run-all support

> Run multiple Terragrunt modules in one deployment with run-all in env zero, enabling CI/CD, drift detection, and cost estimation across all modules at once.

env zero supports a wide variety of IaC platforms, including [Terragrunt](https://terragrunt.gruntwork.io/), but up until now it lacked the support for running multiple modules at the same deployment, a feature that is supported by Terragrunt's [run-all command](https://terragrunt.gruntwork.io/docs/features/execute-terraform-commands-on-multiple-modules-at-once/#the-run-all-command). Another advantage is the ability to define dependencies between Terraform modules in code. Today we are proud to deliver this support out of the box with env zero!

### Terragrunt run-all support

env zero now supports the `run-all` command, which will allow you to utilize all of its features for multiple modules in the same environment: CI/CD, drift detection, cost estimation, and more.

Within Terragrunt template configuration, under `Advanced` settings - check `Execute run-all commands on multiple modules`

When you use a template with `Execute run-all commands on multiple modules` configuration, env0 runs the `terragrunt run-all` command for you, and every module in your templates project is deployed simultaneously.
