terraform-it 0.1.6

A tool to generate Terraform providers from OpenAPI specs and Go SDKs.

Terraform Provider Generator

This tool generates a Terraform provider from an OpenAPI specification and a configuration file.

Prerequisites

• Python 3.6+
• Go 1.16+
• Terraform 1.0+
• GoReleaser (optional, for building and releasing the provider)
• jinja2 (Python package)
• pyyaml (Python package)

Installation

2. Install required Python package:

pip install terraform-it

Usage

tfit openapi-spec.yaml config.yaml --output-dir ./terraform-provider-rivet

Arguments

• openapi_spec.yml: Path to the OpenAPI specification YAML file
• config.yml: Path to the configuration YAML file that defines resources and data sources
• --output-dir: (Optional) Output directory for generated files (default: current directory)

Configuration File Format

The configuration file (config.yml) should define resources and data sources in the following format:

sdk-client-path: SDKClientPath
resources:
  ResourceName:
    resource-path: ResourcePath in SDK
    read:
      method: get
      name: FunctionName in SDK
      path: /path/to/resource/{id}
    create:
      method: post
      name: FunctionName in SDK
      path: /path/to/resource
    update:
      method: put
      name: FunctionName in SDK
      path: /path/to/resource/{id}
    delete:
      method: delete
      name: FunctionName in SDK
      path: /path/to/resource/{id}

datasources:
  DatasourceName:
    read: /path/to/resource/{id}
    list: /path/to/resources
    list-name: FunctionName in SDK

Building the Provider

After generating the provider code, check the CHECK.md file for any manual changes or additions required. Then you can build it with:

cd <output_directory>
go build -o terraform-provider-<provider_name>

Using the Provider

To use the provider in Terraform:

1. Copy the built provider to your Terraform plugins directory
2. Create a Terraform configuration file that uses the provider
3. Run terraform init to initialize the provider
4. Run terraform plan and terraform apply to use the provider
