Thank you for your interest and participation in our recruitment process for our DevOps Engineer position, to continue with the process we ask you to take the following technical test and share your result with us.
24 hours
You'll need:
- A Github account
- A docker hub account
- Access to a kubernetes cluster for testing purposes (It can be Minikube or any other public or private option)
- Fork this repository, then clone it locally.
As a DevOps we need you to create a mechanism to deploy microservices. You'll be in charge of deploy, monitor, scale applications and promote the DevOps culture with the development team. But let's start by the begining, below you'll find the requirements for this exercise.
Dockerize the given service at app.py, including all it's required dependencies installed and ready to rock.
Implement a workflow to build and publish your docker image on docker hub. Please use any CI/CD tool of your preference that you can show us during a quick demo.
Create a service configuration file to deploy the service on your kubernetes cluster and expose it to the world.
- Improve the given python service so it maintains a counter of the amount of POST requests it served, and return it on GET requests.
- Github Actions as CI/CD tool
- GKE to deploy your service
- A link to the public docker registry where the image is published.
- A link to your repository containing:
- The Dockerfile(s) for the image(s).
- The kubernetes file(s) for the service deployment(s). The deployment should be replicable on our kubernetes cluster.
- Optionally the code for the improved version of the service.
Your code should be as simple as possible, yet well documented and robust. Spend some time on designing your solution. Think about operational use cases from the real world. Few examples:
- What happens if a service crashes?
- How much effort will it take to create a new service? D.R.Y!
- How secure is your app?
