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

Configuring ports in Kubernetes


So far in this chapter, we have created our own Kubernetes cluster and deployed our geolocation microservice on the cluster. But unfortunately, we were not able to access our microservice because we haven't exposed our ports (in the dashboard method) or created services (in the kubectl method). In this recipe, we will learn how to map our ports and create services.

Getting ready

When we deploy our application from the friendly form in the Kubernetes dashboard, we have some advanced settings that we could utilize to expose ports. Open the dashboard using the minikube command:

minikube dashboard

Delete any deployments, replication controllers, or services you already have for geolocation. You can leave the echoserver container that we created earlier or delete it-it shouldn't really affect us.

How to do it...

  1. Go ahead and create a new application. Enter the application name geolocation and container image vikrammurugesan/geolocation:latest. This time, configure...
