title: google cloud instance terminate after close browser
body: <p>I have a bash script. I would like to run it continuously on google cloud server. I connected to my VM via SSH in browser but after I've closed my browser, script was stopped.
  I tried to use Cloud Shell but if I restart my laptop, script launches from start. It doesn't work continuously!
  Is it possible to launch my script in google cloud, shut down laptop and be sure what my script works?</p>
