I was trying to setup docker as part of a recent project. I had followed the guide provided by docker to set up docker on my Ubuntu server.
After successfully installing docker on my Ubuntu Server, I was not able to run sudo docker run hello-world successfully.
There is a number dial that changes rapidly and a text field for the user to enter his name. When the user clicks on the "get lucky number" button, jQuery is used to send the lucky number on the number dial and the user name to the server.
The server generates a text file based on the input from the user and sends the file back to the browser. The browser will then show a download dialog box for the user to decide whether to save a copy of the file or view the file using one of the native applications found in his/her computer.
