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.

Building and deploying the microservices

Building, deploying, and verifying the deployment using the test-em-all.bash test script is done in the same way it was done in Chapter 19, Centralized Logging with the EFK Stack, in the Building and deploying the microservices section. Run the following commands:

  1. Build the Docker images from the source with the following commands:
cd $BOOK_HOME/Chapter20
eval $(minikube docker-env)
./gradlew build && docker-compose build
  1. Recreate the namespace, hands-on, and set it as the default namespace:
kubectl delete namespace hands-on
kubectl create namespace hands-on
kubectl config set-context $(kubectl config current-context) --namespace=hands-on
  1. Execute the deployment by running the deploy-dev-env.bash script with the following command:
./kubernetes/scripts/deploy-dev-env.bash 
  1. Start the Minikube tunnel...
