Build Instructions

Build Protocol Buffers

Automated Build

python3 -m venv .venv
source .venv/bin/activate
./proto-build.sh

Verify src/ contains: /envoy, /validate, /xds, /udpa

Manual Build (Step by Step)

If you prefer not to use proto-build.sh:

  1. Install protoc and tools

    See instructions if needed.

    uv sync --group proto

  2. Build Envoy protobufs

    Code to help pull and build is at: https://github.com/cetanu/envoy_data_plane.git. This builds envoy protos in src/envoy_data_plane_pb2/. Copy the envoy directory.

    cd ..
git clone git@github.com:cetanu/envoy_data_plane.git
cd envoy_data_plane
python build.py
cd ..
cp -r envoy_data_plane/src/envoy_data_plane_pb2/envoy plugins-adapter/src/

  3. Get XDS protobufs

    This XDS repo contains python code for validate, xds, and udpa. Go to the python folder.

    git clone https://github.com/cncf/xds.git
cp -rf xds/python/xds xds/python/validate xds/python/udpa plugins-adapter/src/

  4. Install dependencies and run

Ensure by this point you have the envoy, validate, xds, udpa python protobuf folders in src/ to run the external processor server (server.py).

uv sync
uv run python src/server.py
