This repo serves as a minimal examples to reproduce a bug when deploy on GCP Cloud Run

Steps to create this service

If you want to recreate this example from scratch open Visual Studio and create a new project with the "gRPC Service (C#)" template. You need .NET Core 3.1 installed to have access to this template. The only subsequent code modification in the Program.cs file where we explicitly listen to the port number provided by the "PORT" environment variable.

Testing

To build the image:

docker build -f Dockerfile . -t gcr.io/$PROJECT_ID/dotnetgrpctest:latest

To upload the image to gcr:

docker push gcr.io/$PROJECT_ID/dotnetgrpctest:latest

Then deploy on Cloud Run (fully managed) with 'Allow unauthenticated invocations' ticked (Step 3 in the Authentication section)

You can download a client to test this server here.

Or you can create your own client with the official documentation.
