DevOps Assesment Task

The goal of the exercise is to setup all the infrastructure necessary to support the continuous deployment of a NodeJS app. We will be using a public cloud, a Heroku-style PaaS name Dokku and a variety of provisioning and Infrastructure-as-code tools.

Task 1. Setup Dokku*

First you will need to deploy Dokku on a public cloud provider of your choice, we prefer AWS, but GCE, Digital Ocean or Azure are also ok. Use infrastructure-as-code tools to set it up, we suggest Terraform, but Cloudformation, Ansible or others are also accepted.

Task 2. Deploy the NodeJS app

• To get a first taste of Dokku, manually deploy the application as provided (using buildpacks).
• Create a Dockerfile for the app (be mindful of container size).
• Deploy the app again, now making sure Dokku uses the Dockerfile.

Task 3. Set up CI/CD pipelines

Set up a continuous deployment pipeline using a public service like Travis CI, Circle CI or feel free to launch one on your own using Concourse CI or Jenkins for example.

(Optional) Task 4. Propose the ideal CD pipeline

After implementing a successful pipeline describe what in your view would be the ideal CD pipeline. Touch briefly (maximum 2 pages) on each of the following points:

• Branching strategy
• Test stages
• Versioning
• Environments
• Fan-in/ Fan-out stages
• Continuous Delivery or Continuous Deployment
• Release Strategy

Deliverables

• A github, gitlab or bitbucket repo with the code to create all of the above.
• Documentation on how to apply it (it should be brief)
• CD pipeline discussion (if done)

Estimated time to complete: 4 to 6 hours
