Simple Web App

This is a simple web application implemented in ExpressJS that displays the hostname of the server and the current time.

Docker

Build the Docker image using the following command:

docker build -t cac-simple-webapp .

Once the image is built, you can run a container using the following command:

docker run -p 3000:3000 -e PORT=3000 cac-simple-webapp

Prerequisites

The server running the application should have NodeJS (8.x) installed. Read here how to install NodeJS on Ubuntu.

How to install

Clone this repository to the server:

 $ git clone https://github.com/TimothySealy/cac-simple-webapp.git
 $ cd cac-simple-webapp

Install dependencies (once) and then run the application:

 $ npm install
 $ npm run start

Environment variables

The web application runs on port 3000 by default. The port can be changed using the PORT environment variable. For example:

 $ export PORT=80
