This repository defines component-level APIs and common configuration formats for the Istio platform. These definitions are specified using the protobuf syntax.

This repository depends only on the tools repository for tools used during build. This repository will not depend on any other repositories. Except for tools, all other Istio repositories can take a dependency on the api repository.

When making changes to the protos in this repository, your changes must comply with the API guidelines.

After the protobuf definitions are updated, the corresponding *pb.go and _pb2.py files must be generated by running make clean generate and submitted as part of the same PR as the updated definitions. Also make proto-commit must be run to update the proto.lock file with new changes.

If releasing a new tagged version, please update python/istio-api/setup.py version to reflect.

If a PR tries to make backwards incompatible changes, it will be blocked by protolock. To force these changes in, install protolock and run protolock commit --force.

You must include a note in your PR that you had to force the protolock and why.
