Getting started with Kubernetes and Docker with minikube

In this block post, we’ll package applications with Docker containers, and then deploy them with Kubernete in a local minikube cluster. We’ll cover some Kubernete concepts such as Pod, Deployment, Service, etc. Source code is published here.

This is a semi-rerun of an older blog Developing Microservices with minikube. If you are into Typescript and want some step-by-step level of details, check that out instead. We focus more on Kubenetes and Docker instead of building applications here.

There are 3 apps: auth, gateway, and books. They are implemented in 3 different ways.

• Typescript + express.js
• Scala + finch
• Python + flask

They all work similarly, with some very minor differences in how we publish docker images. Now let’s get started.
