Customizing the .NET Runtime

Google Cloud Tools for Visual Studio automatically supplies an app.yaml file and a Dockerfile when you deploy to App Engine. However, you can extend the .NET runtime to add additional functionality by customizing the Docker image. For more information, see Custom Runtimes.

For building .NET containers, Google provides these base images:

.NET Runtime Base Image Health Checks
1.0.7 gcr.io/google-appengine/aspnetcore:1.0.7 Yes
1.1.4 gcr.io/google-appengine/aspnetcore:1.1.4 Yes
2.0.0 gcr.io/google-appengine/aspnetcore:2.0.0 Yes

Health checking

By default, all programs running in the flexible environment receive health check requests, and you don't need to write any additional code.
