Generate Protobuf go code and out.pb

Install protoc by following this.

Run the following code to get the proto dependency.

go get github.com/golang/protobuf/protoc-gen-go
mkdir -p proto/google/api/
curl -sSL https://raw.githubusercontent.com/googleapis/googleapis/master/google/api/annotations.proto --output proto/google/api/annotations.proto
curl -sSL https://raw.githubusercontent.com/googleapis/googleapis/master/google/api/http.proto --output proto/google/api/http.proto

Generate protobuf code and out.pb (used for cloud endpoints deployment).

protoc \
    --proto_path=proto \
    --include_source_info \
    --descriptor_set_out deployment/out.pb \
    --go_out=plugins=grpc:proto \
    proto/mixer.proto

Run grpc server and examples locally

go run server/main.go \
  --bq_dataset=google.com:datcom-store-dev.dc_v3_clustered \
  --bt_table=dc20 \
  --bt_project=google.com:datcom-store-dev \
  --bt_instance=prophet-cache \
  --project_id=datcom-mixer \
  --schema_path=deployment/mapping

cd examples
./run_all.sh

Build mixer docker image and submit to Google Cloud Registry

gcloud builds submit --tag gcr.io/datcom-mixer/go-grpc-mixer:<TAG> .
