Deploying a gRPC Service on Google Cloud Run

Cloud Run for gRPC

This lesson explains the main concept clearly with beginner-friendly examples and background so you can learn why the code works.

1. Dockerfile (same as lesson‑47) – expose port 8080.
2. Build and push the image.

$ docker build -t gcr.io/<PROJECT>/go-grpc .
$ docker push gcr.io/<PROJECT>/go-grpc

3. Deploy with the gcloud CLI:

$ gcloud run deploy go-grpc \
    --image gcr.io/<PROJECT>/go-grpc \
    --platform managed \
    --region us-central1 \
    --allow-unauthenticated \
    --port 8080

4. Enable gRPC in the service settings (check Allow unauthenticated invocations and gRPC protocol).
5. Use the generated client to call the endpoint (ensure grpc.WithTransportCredentials(insecure.NewCredentials())).
