[Lab 13] Canary failed! Scaling down vote.instavote

This error will appear when trying to trigger the Blue/Green deployment on page 9. The reason being that the container schoolofdevops/v2 specified in the kubectl params does not exist on DockerHub:

kubectl -n instavote set image deploy vote vote=schoolofdevops/v2

The following should be used instead:

kubectl -n instavote set image deploy vote vote=schoolofdevops/vote:v2
