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

Setting up Zookeeper using Docker


In Chapter 3 , Deploying Microservices on Mesos, we learned a little bit about Zookeeper. To keep it very simple, Zookeeper is a cluster-management tool that is mainly used for storing your cluster configurations. Zookeeper is used by several Apache big data projects such as Mesos, Kafka, and Bookkeeper. In this chapter, we will see how we can use Zookeeper to store our microservice configurations and later use them to perform load-balancing. This recipe will show you how to start Zookeeper and Exhibitor using Docker. Exhibitor is a management interface for Zookeeper. In addition to providing a web interface to manage Zookeeper, it also performs log file cleanups and backups. We will be using the Exhibitor web interface to verify that our service was registered on Zookeeper.

Getting ready

  1. We now know that we need two components:

    • Zookeeper

    • Exhibitor

    They could either be two individual containers linked together via docker-compose or could coexist in the same...
