devops_assignment

This repo contains all the necessary information/instructions for the DevOps assignment of Impactechs recruitment process.

TL;DR

The assigment has three parts:

• Terraforming - Hack your way into a modular terraform project
• Architecture design - We want to design a new Netflix; well just in paper ;)
• Lets deploy something in Kubernetes - Containerize, deploy and monitor a sample Go application

Terraforming

Dont worry about syntax, we just want to take refactor our Terraform scripts in a best practices project. Some requirements:

• Our DevOps team may work in parallel on the same infrastructure
• We want to avoid duplication - speed is important
• We want to deploy to 3 environments: Dev, Stage, Production
• Versions change, but it shouldn't break our scripts

What to deliver?

• A refactored project! Easily maintainable, modular and extendable
• A very brief explanation how you tackled the requirements. Code snippets are fine as well

Architecture

Netflix is awesome! We want to design our own streaming platform and some requirements are:

• Users should authenticate and authorized to access their accounts
• Users can save, rate and recommend to a friend any stream
• We would like to send recommendations to the users as well; lets dont waste time searching for what they might like
• Our billing should be instant, and accounting should have live feed on the data
• Our Dev would like to A/B test their new cool clent-side frontend design
• Our Ops team needs to monitor and be alerted for any issues

What to deliver?

An architecture diagram depicting the services and any infrastructure pieces the new Netflix will need. Here is the catch; Also write us some notes on the problems you see in your design.

Deploy something

We have included a dummy Golang (1.12) microservice which exposes 3 endpoints on port 8080:

• /demo/random-error -> Randomly something goes wrong
• /demo/hello -> Hello world!
• /metrics -> We need to monitor some metrics

go get -d -v -t
go test --cover -v ./... --run UnitTest
go build -v -o go-demo

This app should be containerized and should be shipped in a brand new K8s cluster. So we would like to:

• Deploy a Prometheus server to monitor our app
• Deploy our app which should be accessible externally
• Our app should be highly available and scale based on resources automatically

What to deliver?

• A Dockerfile
• All the K8s deployment manifests that are needed to configure our monitoring and deploy our app into a cluster. You can use simple k8s manifests, Helm or kustomize. Totally up to you.
• Some notes on what else we might need for Ops or Dev
