Hands-On Microservices with Spring Boot and Spring Cloud

By: Magnus Larsson

Overview of this book

Microservices architecture allows developers to build and maintain applications with ease, and enterprises are rapidly adopting it to build software using Spring Boot as their default framework. With this book, you’ll learn how to efficiently build and deploy microservices using Spring Boot. This microservices book will take you through tried and tested approaches to building distributed systems and implementing microservices architecture in your organization. Starting with a set of simple cooperating microservices developed using Spring Boot, you’ll learn how you can add functionalities such as persistence, make your microservices reactive, and describe their APIs using Swagger/OpenAPI. As you advance, you’ll understand how to add different services from Spring Cloud to your microservice system. The book also demonstrates how to deploy your microservices using Kubernetes and manage them with Istio for improved security and traffic management. Finally, you’ll explore centralized log management using the EFK stack and monitor microservices using Prometheus and Grafana. By the end of this book, you’ll be able to build microservices that are scalable and robust using Spring Boot and Spring Cloud.

Managing a Kubernetes cluster

A running Kubernetes cluster consumes a lot of resources, mostly memory. So, when we are done working with a Kubernetes cluster in Minikube, we must be able to hibernate it in order to release the resources allocated to it. We also need to know how to resume the cluster when we want to continue working with it. Eventually, we must also be able to permanently remove the cluster when we don't want to keep it on disk anymore.

Minikube comes with a stop command that can be used to hibernate a Kubernetes cluster. The start command we used to initially create the Kubernetes cluster can also be used to resume the cluster from its hibernated state. To permanently remove a cluster, we can use the delete command from Minikube.

Hibernating and resuming...
