Microservices Deployment Cookbook

By: Vikram Murugesan

Overview of this book

This book will help any team or organization understand, deploy, and manage microservices at scale. It is driven by a sample application, helping you gradually build a complete microservice-based ecosystem. Rather than just focusing on writing a microservice, this book addresses various other microservice-related solutions: deployments, clustering, load balancing, logging, streaming, and monitoring. The initial chapters offer insights into how web and enterprise apps can be migrated to scalable microservices. Moving on, you’ll see how to Dockerize your application so that it is ready to be shipped and deployed. We will look at how to deploy microservices on Mesos and Marathon and will also deploy microservices on Kubernetes. Next, you will implement service discovery and load balancing for your microservices. We’ll also show you how to build asynchronous streaming systems using Kafka Streams and Apache Spark. Finally, we wind up by aggregating your logs in Kafka, creating your own metrics, and monitoring the metrics for the microservice.

Preface

Destroying your microservice in Kubernetes


So far in this chapter, we've learned how to deploy and scale our microservice in a Kubernetes cluster. There will be scenarios where you would want to destroy your microservice completely from your cluster, probably because you would like to perform a clean redeploy. In this recipe, we will learn how to destroy our microservice.

Getting ready

Open up the Kubernetes dashboard if you already have your cluster running. If not, use Minikube to start the cluster and open the dashboard. Make sure there are no instances of the geolocation container running on your Kubernetes cluster. If you have any instance of geolocation running, delete the replication controllers, services, and pods.

How to do it...

  1. To illustrate the destroy functionality, let's deploy the geolocation microservice first. Use the friendly form and enter the following configurations to create your microservice:

    • App name: geolocation

    • Container image: vikrammurugesan/geolocation:latest

    • ...
