Deploy ASP.NET Core Application different image verison in Kubernetes

Deploying the pods (individually or with a replication controller), using the same labels, except for the version, for which you use the value v2. 

Modified the code (frontendmvc).

Build the image, re name the image tag version 2 & publish the image to Docker Hub

docker build -t frontendmvc .
docker tag frontendmvc makader/myapp:frontendmvc-v2
docker push makader/myapp:frontendmvc-v2

Create a Kubernetes service using a YAML

Instead of exposing directly (see the blog), create a service in a declarative way using a YAML file

forntendmvc_service .yaml
