Implementing a MEAN App using Lightsail

Welcome to this Amazon Lightsail learning activity where we will be implementing the `MEAN` stack within a single Lightsail instance. The goal of this learning activity is to gain knowledge and experience with: * Creating a Lightsail instance, complete with a pre-installed stack. * Using a Launch Script to perform advanced configuration. * Interacting with an "on-instance" MongoDB. * Connecting to the instance to configure a MEAN based application. * Application testing and verification. Good look and enjoy the learning activity.

Challenge

Build the Lightsail Instance using the MEAN Blueprint.
- Create a Lightsail Instance, using Linux/Unix as the platform and the MEAN Apps + OS blueprint
  
  Add a launch script (linked below)
  
  Name the instance MEAN
  
  Ensure it's created in us-east-1
  
  Pick the 2 GB memory instance size
- Connect to the instance and verify the todo-mean directory exists in the home folder.
Launch Script for the activity

Challenge

Configure the "on-instance" MongoDB.
- Connect to the MEAN instance using SSH.
- Connect to the MongoDB instance as root:
- Change to the tasks database:
- Create a Database User called tasks with the password of tasks and the dbOwner role:
https://github.com/linuxacademy/aws-lightsail-deep-dive/blob/master/Scenario2/mongodbsetup.sh
- Exit the MongoDB shell (exit).
Challenge

Start and test the application.
- Move into the todo-mean directory in your users folder on the instance.
- Start the application using sudo DEBUG=app:* ./bin/www
- Verify the application is running via a web browser at http://instancepublicIP
