for the other newbies, heres a more detailed description for Windows users who installed Ubuntu:
Open ubuntu terminal
run vim ~/.bash_profile
inside the new terminal, copy in the above exports with your names and types.
type: :wq and press Enter. this saves the file and returns you to the ubuntu terminal
run source ~/.bash_profile
start up your instance from the console and re-run gcloud compute ssh
