Solution

Created a Dockerfile to containerize the application, used multi stage build to reduce image size. Pushed the image to my personal docker hub account.

Used Google Kubernetes Engine on Google Cloud as kubernetes cluster. Created ingress, service, deployment and backend-config resources. When i create ingress on GKE it creates backend services on LB and default path of backend services' health check is "/". But our application doesnt serve anything on path "/" so our backend services gets unhealthy state.

To fix that i create a backend-config resource and update the path as "/WeatherForecast" also i add an extra annotation on service to use my custom backend-config resource. With that backend services gets healthy state and ingress works.

You can test the application on http://34.120.2.10/WeatherForecast

Yaml files are under infra/ and to one click installation you can run setup.sh

I draw a small diagram to show flow.
