Installer for Envoy Protobuf files

Project description

envoy-proto-builder

https://img.shields.io/pypi/v/envoy_protobuf.svg https://img.shields.io/travis/dpetzold/envoy_protobuf.svg

Builds and installs Envoy protocol buffers and the following dependencies:

  • data-plane-api
  • googleapis
  • protoc-gen-validate
  • opencensus-proto

How it works

Clones the Envoy repository and associated dependencies to a temporary location. Builds the proto files into virtual Python module and installs the module with pip. The protobuf files are available in envoy_proto.

Installation

pip installl envoy-proto-builder

Usage

Running with no arguments will install the Envoy files from the master branch.

usage: envoy-protobuf-builder [-h] [--version VERSION] [--src-dir SRC_DIR] [--no-clone]

optional arguments:
  -h, --help         show this help message and exit
  --version VERSION  The Envoy version to build. Defaults to master.
  --src-dir SRC_DIR  The directory to clone the repositories to. If not specified a temporary
                     location is used.
  --no-clone         Build the files with cloning the repositories.
