Protobuf and gRPC interfaces#
This package contains Protobuf definitions for the various types, messages and interfaces that Pulumi components use to communicate. These definitions serve as the source of truth for several parts of the wider codebase.
Code generation#
Note
Code generated from Protobuf files is committed to the repository. If you change
one or more .proto files, you should run make build_proto to regenerate the
necessary stubs and commit the changes as part of the same piece of work.
The pulumi/pulumi:proto/generate.sh script in this directory (called by the
build_proto target in the top-level pulumi/pulumi:Makefile) generates types
and gRPC clients for the languages supported in this repository (Go,
NodeJS/TypeScript and Python). Generated code is committed to the repository,
typically in proto directories at the relevant use sites (e.g.
pulumi/pulumi:sdk/nodejs/proto).
Documentation#
We use the protoc-gen-doc
plugin to protoc to generate
Markdown documentation from the Protobuf files. This process is handled by the
pulumi/pulumi:docs/Makefile in the docs directory and uses the
pulumi/pulumi:docs/references/proto.md.tmpl template. Generated documentation ends
up in the docs/_generated directory (which is .gitignored), so e.g. this
index links to files in this folder.
