App Engine Flex - Specify Dot Net Runtime version

Question

I'm building an app with .NET core on Google App Engine flex. These are two top-level items in my app.yaml file...

runtime: aspnetcore
env: flex

Is there a way I can ensure that it runs on the dotnet 2.1 runtime? How do I specify that I want it to run on .NET CORE 2.1.

Answer 1

You can set your runtime as custom and then create a Dockerfile with the runtime configuration you want. In this case:

FROM gcr.io/google-appengine/aspnetcore:2.1

Here you can check the documentation about Building Custom Runtimes
