Reference video in case if you need help getting Rails applications to be public on Google Cloud.
Covered in this video:
* Running Rails on the correct IP/port: `bin/rails server -b 0.0.0.0 -p 8080`
* Note: the port doesn't matter as long as you have it open in the local/VPC firewall AND your client knows where to connect!
* Opening firewall ports:
* In Ubuntu: `sudo ufw allow 8080`
* In Google VPC:
* Navigate to VPC firewall, edit default-allow-http, add on `,8080` to the TCP rule..
One thing I forgot to mention, if you want to leave it running and be able to close your SSH session, run it in tmux and detach before closing!
