Set up a Local Kubernetes Cluster

Install Docker: Follow the installation guide for Docker based on your operating system: Docker Installation Guide.

Install Kubernetes: Use a tool like minikube or kind to set up a local Kubernetes cluster. Choose one of the following options:

• Minikube: Follow the installation guide for Minikube: Minikube Installation Guide.
• Kind: Follow the installation guide for Kind: Kind Installation Guide.

Implement a RESTful API that exposes an endpoint to check if a number is prime or not. The API should accept a POST request to the /prime endpoint and return a JSON response indicating whether the number is prime or not.

You may use any language that you want.

• Example Request

  POST /prime
  {
  "number": 7
  }

• Example Response

  Prime Number

  {
  "number": 7,
  "prime": true
  }

  Non-Prime Number

  {
  "number": 4,
  "prime": false
  }

Deploy the API built previously to the kubernetes cluster.

Use ArgoCD and GitOps principles to make this happen.

ArgoCD Installation Guide

• Implement a CI/CD pipelines that builds, package, test and deploy the solution. You may use any CI/CD tool like GitHub, Gitlab, Buildkite, etc.
• Unit testing

To complete the exercise, the candidate should provide the following:

• The code for all the solution that includes:
  • RESTful API code;
  • Dockerfiles;
  • ArgoCD app manifests;
  • Kubernetes deployment manifests.
• Any additional instructions or documentation that may be required to run or test the solution.
