Scenario

Alpine Inc has recently built a web application that allows users to record simple Notes application. The application is built using NodeJs, Express and backed by a NoSQL MongoDB.

The source code for this application is stored in GitHub but the code itself is built and deployed manually from the lead developer’s (Pete) laptop. Although this process has worked in the past, Pete had recently taken leave from work which has meant that Alpine Inc missed a critical release that contained a new feature for one of their largest clients.

There have also been instances where bugs have been introduced into production which has caused an increase in the number of support calls from their customers, and the support and development teams have had to work overtime to manage the load and ?x the issues. These issues are causing reduced morale among the teams, as well as impacting the revenue of Alpine Inc.

As the newly hired DevOps practitioner, Alpine Inc has turned to you to help resolve their issues and enable their teams to better deliver new features and ensure releases into production are quick and reliable.

To help kick off this transformation, you have proposed that Alpine Inc start looking at establishing a CI pipeline to help reduce dependency on Pete by introducing automated builds and automate their testing processes. This will reduce the strain on the QA team and ensure bugs and development defects are picked up quickly and fed back to developers to be resolved before any changes are promoted to production.

The Approach

To make this easier for Alpine Inc, which is rather immature with DevOps methodologies and practices, you have opted to use SaaS tools where possible to help reduce the learning curve for their development team. You will follow best practice principles and make as much of your solution using code, this includes your CI build con?guration and scaffolding scripts.

Tools to use:

  • GitHub (GitHub Classroom)
  • GitHubActions – used for creating the pipelines
  • Docker
  • DockerCompose
  • Basicnpm commands

After a lengthy and heated debate amongst the team, it was decided to use  GitHub Flow as the branching strategy. Rather than committing directly to the “main” branch, it was agreed to always use feature branches and pull requests. However it was also agreed that engineers could approve their own PR’s.

Deliverable

Alpine Inc expects you update your GitHub classroom repository with the code and documentation required to run the Continuous Integration build you are creating for them including all ?les.

You task is to:

  1. De?nea CI pipeline by creating a ?le in the .github/work?ows  Your pipeline will automatically execute on GitHub Action runners.
  2. De?neyour md.

Note that when you implement things like linting and end-to-end testing, you might discover bugs or errors which the development team had not noticed before! You will need to ?x them so that your pipeline passes. (Hint: some of the package versions pinned by the dev team in package.json might need to be “bumped” to operate in a more current environment.)

Access GitHub Classroom

We will be using Github classroom to edit and manage the code base. All the core ?les for the application will be provided to you here. Please accept the invite below to join the classroom and get access to Assignment #1. You will be expected to work and make your commits to this repo.

Marking Guide

The Alpine Inc team needs to be able to understand why you chose to approach your solution the way you did. Create a document with details for each of the elements in your solution, explain how the element works and how it forms part of the overall DevOps process. Write as little as possible to communicate your message. Add screenshots where appropriate to demonstrate that you have completed the requirements of each section.
