Not sure why, if the user already existed (eg: already SSH logged in google web console), it doesn't work when I manually added SSH keys into metadata on google web console. I have tried hundred of times from the steps below.

I found out you have to manually add your ssh key through web SSH CONSOLE -> ssh in on google web console and copy ssh pub key on your local machine (usually is in ~/.ssh/) and append (edit and paste to the end) it to ~/.ssh/authorized_keys.
