Graphical Terraform configuration generator

Terraforge is an application for generating Terraform code visually. Users select providers and then add resources as nodes to a graph that can be edited and arranged. Links between nodes appear automatically as the configuration of a node makes references to other nodes. When finished the design can be exported as Terraform HCL. The configuration will include all settings and configurations entered for the nodes.

Background

Terraform is a tool for managing infrastructure and APIs in a codified manner utilizing a combination of a command-line application, a series of vendor specific plugins, and a declarative configuration language written in HCL. The configuration uses a flat file structure with layers of abstraction attained through local and remote modules. Writing Terraform configurations create many complex relationships between resources since each resource may rely on attributes of others.

The Terraform application generates a Directed Acyclic Graph (DAG) based on the configuration which establishes the correct order of resource manipulation. There are several tools that allow users to input configuration files then output and visualize the DAG. However, there seems to be a lack of any tool that can reverse this process, starting with a visual representation of the desired infrastructure and exporting the Terraform code. This was the inspiration for Terraforge.

Get started

Running the App

Install the dependencies...

git clone https://github.com/badarsebard/terraforge.git
cd terraforge
npm install

...then start Rollup:

npm run dev

Navigate to localhost:5000. You should see the app running.

Using the App

To get started right away use the Wizard under the Providers menu.

• Select the Official and AWS checkboxes in the modal and click Submit.
• Select the hashicorp/aws provider from the dropdown on the right and choose either resource or data source radio buttons.
• Double-click an entry to add a node of that type to the graph in the center of the page.
• Click a node to open a pane on the left-hand side of the window where the name and attributes of the node can be modified.
• References between nodes can be made by entering $type.name.attributes in the attribute; e.g.$aws_lb.front_end.arn.
• After creating and editing some resources, export the Terraform configuration by using Export in the HCL menu.
• The browser will download a file called terraforge.tf which will contain the Terraform configuration represented by the diagram and based on the configurations entered.

resource "aws_lb" "front_end" {}
resource "aws_lb_listener" "https" {
  load_balancer_arn = aws_lb.front_end.arn
}

Please note that the app is unable to, at this time, execute any Terraform commands so the output is unformatted and unvalidated.

See all the details about the editor and its components.

Save and load work using design import and export.

Turn your graph into a Terraform config by exporting HCL or pick up with an existing project using the import feature.
