Now thinking about tag based routing it doesn’t make sense at the end.

I think I will change it to a story that starts with 0% traffic and tag for the new version hello-00002 and the user first test the new version before making available to anyone, then increase from 0% to 50% then finishing with 100% to latest v2

Thanks for making these improvements!

I've made some suggestions to improve consistency and style.

I think there are some other useful things in this PR such improving the curl commands for minikube. Do you plan to remove the tag parts from this PR so that we can merge the rest?

[csantanapr]

I will create a new PR for the tag stuff, and remove it from this one

[csantanapr]
