About this Hands-on Lab

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.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

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

https://github.com/linuxacademy/aws-lightsail-deep-dive/blob/master/Scenario3/learning_activity_1/launchscript.sh

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:

  • Exit the MongoDB shell (exit).
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

Additional Resources

  • Make sure you are in the us-east-1 region.
  • Use the provided credentials to log in to the AWS management console.
