Cuemata

This project generates CUE schemas for Pulumi providers, based on schema.json files published with their source code. These CUE schema files are intended to be used with Pulumi’s YAML language provider, when one wants to write resource definitions using CUE instead of YAML.

See examples/ directory for some use cases.

Tools

• cue-pulumi-gen: a program to generate CUE definitions for Pulumi providers' JSON schemas inside schemata/pulumi/provider/ directory

• pulumi-schema: a simple command to conveniently print out schema.json file, given a Pulumi provider’s name

Schema packages

• All CUE packages inside schemata/pulumi/provider/ directory are auto-generated. See providers.toml file for the full list of providers and their JSON schema sources.

• Package schemata/pulumi defines CUE schema for:

  • Pulumi.yaml in pulumi.cue. It is extended upon https://github.com/SchemaStore/schemastore/blob/master/src/schemas/json/pulumi.json with support for pulumi-yaml definitions.

  • schema.json (package metaschema) for a Pulumi provider in package.cue. The CUE definition is imported by cue CLI from https://github.com/pulumi/pulumi/blob/master/pkg/codegen/schema/pulumi.json.

Reference

• Pulumi’s YAML specs

• Pulumi’s package schema
