Terragrunt

Terragrunt is a flexible orchestration tool that allows Infrastructure as Code written in OpenTofu/terragrunt to scale.

🚀 Usage

Add the following command to your CI configuration file:

fluentci run --wasm terragrunt hclfmt --terragrunt-check --terragrunt-diff
fluentci run --wasm terragrunt validate
fluentci run --wasm terragrunt apply

Commands

Name	Description
setup	Install terragrunt cli
hclfmt	Recursively find hcl files and rewrite them into a canonical format.
plan	Generate and show an execution plan.
apply	Apply the changes required to reach the desired state.

Code Examples

Add fluentci-pdk crate to your Cargo.toml:

[dependencies]
fluentci-pdk = "0.2.1"

Use the following code to call a module function:

use fluentci_pdk::dag;

// ...

dag().call("https://pkg.fluentci.io/[email protected]?wasm=1", "hclfmt", vec!["-terragrunt-check", "--terragrunt-diff"])?;
dag().call("https://pkg.fluentci.io/[email protected]?wasm=1", "plan", vec![])?;
dag().call("https://pkg.fluentci.io/[email protected]?wasm=1", "apply", vec![])?;
