This is a level 1 challenge for candidates who want to join our DevOps team.

It is designed to test your level of familiarity with development and operations tools and concepts.

Create a simple microservice in any programming language of your choice, as follows:

• The application should be a web server that returns a JSON response, when its / URL path is accessed:

{
  "timestamp": "<current date and time>",
  "hostname": "<Name of the host (IP also accepted)>",
  "engine": "<Name and/or version of the engine running>",
  "visitor ip": "<the IP address of the visitor>"
}

• Create a Dockerfile for this microservice and publish the image to Docker Hub. Your application must be configured to run as a non-root user in the container.

• Create a Kubernetes manifest in YAML format, containing a Deployment and a Service, to deploy your microservice on Kubernetes. Your Deployment must use your public Docker image.

• Publish your code, Dockerfile, and Kubernetes manifests to a public Git repository in a platform of your choice (e.g. GitHub, GitLab, Bitbucket, etc.), so that it can be cloned and tested by the team.

Your task will be considered successful if a colleague is able to deploy your manifest to a running Kubernetes cluster and use your microservice correctly.

• Code quality and style: your code must be easy for others to read, and properly documented when relevant.

• Container best practices: your container image should be as small as possible, without unnecessary bloat.
