   ii. create automated build (pull out from the top menu)
   iii. connect to github repo you have just created
   

5. make a change on the github repo (to trigger build)

6. Verify that the build succeeded https://hub.docker.com/r/yourdockerhubid/webserver/builds/

docker run -d --name ws -p80:80 yourdockerhubid/webserver

8. Click "Create" button at the bottom

9. Check if the webserver works

     i. enter the external ip adress (for the machine you created) in your browser (you should get your name)
     ii. If that does not work connect to the machine
     iii. Open shell
     iv. type gcloud compute ssh "your instance name"
     v. once connected to your instance type 'docker ps': your container should be running
   

10. Enter ip adress of the machine at the bottom of your netid.md file in the CS340-19/students repo and create a pull request
