OpenAPI Provider Spec Generator

Terraform Provider Code Generation is currently in tech preview. If you have general questions or feedback about provider code generation, please create a new topic in the Plugin Development Community Forum.

Overview

The OpenAPI Provider Spec Generator is a CLI tool that transforms an OpenAPI 3.x Specification (OAS) into a Provider Code Specification.

A Provider Code Specification can be used to generate Terraform Provider code, for example, with the Plugin Framework Code Generator.

Documentation

Full usage info, examples, and config file documentation live on the HashiCorp developer site: https://developer.hashicorp.com/terraform/plugin/code-generation/openapi-generator

For more in-depth details about the design and internals of the OpenAPI Provider Spec Generator, see DESIGN.md.

Usage

Installation

You install a copy of the binary manually from the releases tab, or install via the Go toolchain:

go install github.com/hashicorp/terraform-plugin-codegen-openapi/cmd/tfplugingen-openapi@latest

Generate

The primary generate command requires a generator config and an OpenAPI 3.x specification:

tfplugingen-openapi generate \
  --config <path/to/generator_config.yml> \
  --output <output/for/provider_code_spec.json> \
  <path/to/openapi_spec.json>

Examples

Example generator configs, OpenAPI specifications, and Provider Code Specification output can be found in the ./internal/cmd/testdata/ folder. Here is an example running petstore3, built from source:

go run ./cmd/tfplugingen-openapi generate \
	--config ./internal/cmd/testdata/petstore3/generator_config.yml \
	--output ./internal/cmd/testdata/petstore3/provider_code_spec.json \
	./internal/cmd/testdata/petstore3/openapi_spec.json
