This is NodeJS based application designed to showcase microservices hosted in local Docker or Kubernetes with local docker registry images. Application contains 1x WebApp service + 2x REST API services where one of the service is internal which is not directly accessible from internet.

Overview

This is simple nodejs based application designed to showcase microservices in docker and kubernetes. Application contains one web application and two REST api services where one of the service is internal which is not directly accessible from internet.

Configuration demonstrates basics how to setup local docker registry and local kubernetes hosting. e.g. If you want to create own private cloud solution.

❕ Please notice that example is documented based on Windows host.

Architecture

All application services used in showcase are written with NodeJS.
