This is one of the core repositories of Flyte. It contains the Specification of the Flyte Language using protobuf messages, the Backend API specification in gRPC, and Swagger REST. The repo contains the generated clients and protocol message structures in multiple languages. Along with the generated code, the repository also contains the Golang clients for Flyte’s backend APIs (the services grouped under FlyteAdmin).

Tooling for Flyteidl

  1. Run make download_tooling to install generator dependencies.

   make download_tooling
  1. Ensure Docker is installed locally.

  2. Run make generate to generate all the code, mock client, and docs for FlyteAdmin Service.

    make generate
  1. To add new dependencies for documentation generation, modify and run

   make doc-requirements.txt

Docs structure

The index.rst files for protos are arranged in parallel under the docs folder. All the proto definitions are within protos/flyteidl and their corresponding docs are in protos/docs.

├── admin
│   ├── admin.rst
│   └── index.rst
├── core
│   ├── core.rst
│   └── index.rst
├── datacatalog
│   ├── datacatalog.rst
│   └── index.rst
├── event
│   ├── event.rst
│   └── index.rst
├── plugins

├── service

Each module in protos has a module in docs with the same name. For example: protos/flyteidl/core has a module protos/docs/core under the docs folder which has the corresponding index and documentation files.

Generating Documentation

  • If a new module is to be introduced, follow the structure for core files in file which helps generate the core documentation from its proto files.

     core_proto_files=`ls protos/flyteidl/core/*.proto |xargs`
     # Remove any currently generated file
     ls -d protos/docs/core/* | grep -v index.rst | xargs rm
     protoc --doc_out=protos/docs/core --doc_opt=restructuredtext,core.rst -I=protos `echo $core_proto_files`
  • make generate generates the modified rst files.

  • make html generates the Sphinx documentation from the docs folder that uses the modified rst files.
