Simple App

What is this?

This app is for demo purposes only. It consists of a frontend in node.js (v6.x) that displays data from a table from a MySQL backend (AWS RDS). The intent is to showcase

• CI pipeline using TravisCI
• Auto-provisioning (and teardown) of AWS EC2 instances via AWS CLI

Usage

git clone https://github.com/sosimon/simple-app.git
cd simple-app
npm install
node app.js

Hit http://localhost:3000/

CI

We're using TravisCI; the configuration is defined in .travis.yml. The following is a description of the sequence of activities.

1. Set environment variables
   • AWS access keys - AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY will need to change depending on the AWS account being used
2. Setup (before_install)
   • Install AWS CLI
   • EC2 - setup.sh will spin up a new instance and attempt to verify the SSH connection
   • RDS - MySQL instance already setup; no configuration required
3. Testing (script)
   • Lint - lint.sh, which runs npm run lint
   • Unit tests - INCOMPLETE
4. Deploy (script)
   • Deploy app to EC2 - package app (tar.bz2), SCP to remote instance and extract
   • Integration tests on the EC2 instance - test.sh, which runs npm run test
5. Teardown (after_script)
   • teardown.sh: remove SSH keypair and terminate EC2 instance
