Google Discovery to OpenAPI 3.x Converter

Generates OpenAPI 3.x specification from Google Discovery documents.

OpenAPI 3 Specifications for Google Cloud APIs can be found at stackql/stackql-provider-registry

Overview

This script performs the following steps:

1. Gets the root discovery document for all Google APIs
2. Gets each respective service discovery document from the root discovery document (can be filtered to only fetch preferred service versions)
3. Converts each service discovery document to an OpenAPI 3.x specification, written as a yaml file to the openapi folder

The resultant OpenAPI service specifications can the be used with stackql/openapisaurus to generate StackQL Google provider definitions.

Inspect

PROVIDER_REGISTRY_ROOT_DIR="$(pwd)/openapi"
REG_STR='{"url": "file://'${PROVIDER_REGISTRY_ROOT_DIR}'", "localDocRoot": "'${PROVIDER_REGISTRY_ROOT_DIR}'", "verifyConfig": {"nopVerify": true}}'
./stackql shell --registry="${REG_STR}"

Publish to the StackQL Provider Registry

Raise a PR to add the provider from openapi/src to the stackql-provider-registry. Once merged into the dev branch it will be tested and deployed to the dev registry, which can be accessed via:

# google cloud shell example...
curl -L https://bit.ly/stackql-zip -O && unzip stackql-zip
# use the following to test from the dev provider registry with interactiva authentication
DEV_REG="{ \"url\": \"https://registry-dev.stackql.app/providers\" }"
AUTH='{ "google": { "type": "interactive" }}'
./stackql --auth="${AUTH}" --registry="${DEV_REG}" shell
