A comment on Jsonnet – The Data Templating Language.

Re:Jsonnet – The Data Templating Language by gillh on Monday March 27, 2023 @01:49PM (#35329883)
We use Jsonnet extensively in Aperture project for generating control policies.

- Policy spec is expressed in protobuf format

- GRPC gateway plugin is used to generate Swagger (OpenAPI v2) spec from proto files

- Jsonnet bindings are generated from Swagger spec.

- Blueprints are implemented using Jsonnet bindings. The users generate policies from blueprints by providing configuration in yaml (using aperturectl CLI) or via jsonnet mixin.

- Generated doc example: https://docs.fluxninja.com/development/reference/policies/bu...

- CLI for generating policies from blueprints: https://docs.fluxninja.com/development/reference/aperturectl...

- Policy spec: https://docs.fluxninja.com/development/reference/policies/sp...

I'm interested in the code that processes the swagger/openapi into jsonnet, can you link to that?

It’s customized to our policy spec. But you can learn from this and adapt it to your spec.
