This application is thought for explore service composition, 4 | client load balancing and configuration management. The web main application is composed by two pages under security: 5 | * a web page for standard users in order to get a special hello with a random special message for you on the root or /index.html web application path 6 | * a web page for admin user in order to manage the special message list on for /messages.html web application path. 7 | * there exist a prebuilt user for both web application 8 | * username **user** and password **secret** for /index.html web application 9 | * username **admin** and password **secret** for /messages.html web application 10 | 11 | ### Web Application for simple user screenshot 12 | ![](https://raw.githubusercontent.com/mrFlick72/spring-cloud-kubernetes-demo/master/images/user_webapp.png) 13 | 14 | 15 | ### Web Application for admin user screenshot 16 | ![](https://raw.githubusercontent.com/mrFlick72/spring-cloud-kubernetes-demo/master/images/messages_webapp.png) 17 | 18 | ## The technology stack 19 | 20 | In this project you can see used many technologies like: 21 | 22 | * Spring Cloud Gateway: the reactive Spring counterpart of Zuul, build on Spring 5.x and Webflux 23 | * Spring Cloud Kubernetes 24 | * Spring Cloud LoadBalancer 25 | * Spring Reactive Data Mongo 26 | * Spring WebFlux 27 | * Spring Boot 3.x 28 | * Spring Session 29 | * Spring Reactive Security 30 | * Java/Kotlin 31 | 32 | 33 | ## How it works 34 | 35 | Basically on the UI thankful to Spring Cloud Gateway, similarity to Zuul, we can configure a micro proxy between ui-interface and the backend services. All the magic 36 | is performed by the yml configuration. Even if, in any talk on Spring Cloud Gateway probably you can see the java config way, in this example I preferred yml config in order to 37 | can benefit of hot reload route. The configured routes will be useful to get the hello message on the main web application and create or delete special messages on the 38 | messages web application accessed by admin users. the snippet of code that implements this magic is like below: 39 | 40 | ```yaml 41 | spring: 42 | cloud: 43 | gateway: 44 | routes: 45 | - id: hello-service 46 | uri: lb://hello-service/ 47 | predicates: 48 | - Path=/hello-service/** 49 | filters: 50 | - StripPrefix=1 51 | 52 | - id: message-service 53 | uri: lb://message-service/ 54 | predicates: 55 | - Path=/message-service/** 56 | filters: 57 | - StripPrefix=1 58 | ``` 59 | 60 | On hello-service, instead the integration with message-service is performed by a classic rest service call using a WebClient.Builder annotated with @LoadBalanced in order to 61 | benefit of the *LoadBalancerExchangeFilterFunction* injected by spring for us. The configuration is very simple and the usage is a classical rest service call via WebClient: 62 | 63 | #### load balancer confguration 64 | ```java 65 | @SpringBootApplication 66 | public class HelloServiceApplication { 67 | 68 | ... 69 | 70 | @Bean 71 | @LoadBalanced 72 | public WebClient.Builder loadBalancedWebClientBuilder() { 73 | return WebClient.builder(); 74 | } 75 | 76 | } 77 | ``` 78 | #### service integration 79 | 80 | ```java 81 | 82 | @Slf4j 83 | @Service 84 | class HelloService { 85 | 86 | ... 87 | 88 | Mono sayHello(String name) { 89 | return webClientBuilder.get() 90 | .uri(helloServiceUri) 91 | .retrieve() 92 | .bodyToMono(HashMap.class) 93 | .flatMap(payload -> just(format(TEMPLATE, name, INSTANCE_ID, payload.getOrDefault("message", DEFAULT_MESSAGE)))); 94 | } 95 | } 96 | ``` 97 | 98 | The application.yml configuration provided via config map. The benefit of use configmap 99 | with Spring Cloud Kubernetes is that configuring restart actuator endpoint with spring cloud kubernetes configuration in the application.yml, we can benefit of a hot reload configuration mechanism 100 | via Spring application context restart. 101 | 102 | The application is totally reactive and no blocking io. It involved: 103 | 104 | * Spring Cloud Gateway instead of Zuul 105 | * Spring WebFlux instead of a classical Spring MVC 106 | * Spring Data Reactive Mongo instead of Spring Data Mongo 107 | * WebClient instead of a plain RestTemplate 108 | 109 | Another point of attention may be the usage of Spring Session on Redis for in order to achieve a totally scalable application, without sticky session or something like that. 110 | 111 | ## How build the project 112 | In this spike I will use minikube like k8s local environment. In order to speed up a fresh minikube instance for this purpose 113 | you can use this command: 114 | ```minikube start --vm-driver=virtualbox --cpus 4 --memory 8192 -p spring-cloud-k8s``` 115 | 116 | Remember to enable ingress with this command: ```minikube addons enable ingress -p spring-cloud-k8s``` 117 | In order to test on minikube you can use my docker images on docker hub and that's it install the kubernetes manifests via helm chart under helm folder. 118 | 119 | if you want you can try it online ;) [user page](https://spring-cloud-kubernetes-demo.vvaudi-lab.com/index.html), or [admin page](https://spring-cloud-kubernetes-demo.vvaudi-lab.com/messages.html) 120 | -------------------------------------------------------------------------------- /hello-service/.gitignore: -------------------------------------------------------------------------------- 1 | HELP.md 2 | .gradle 3 | /build/ 4 | !gradle/wrapper/gradle-wrapper.jar 5 | 6 | ### STS ### 7 | .apt_generated 8 | .classpath 9 | .factorypath 10 | .project 11 | .settings 12 | .springBeans 13 | .sts4-cache 14 | 15 | ### IntelliJ IDEA ### 16 | .idea 17 | *.iws 18 | *.iml 19 | *.ipr 20 | /out/ 21 | 22 | ### NetBeans ### 23 | /nbproject/private/ 24 | /nbbuild/ 25 | /dist/ 26 | /nbdist/ 27 | /.nb-gradle/ 28 | 29 | ### VS Code ### 30 | .vscode/ 31 | -------------------------------------------------------------------------------- /hello-service/Dockerfile: -------------------------------------------------------------------------------- 1 | FROM amazoncorretto:17.0.4 2 | 3 | ADD build/libs/hello-service.jar /usr/local/hello-service/ 4 | 5 | WORKDIR /usr/local/hello-service/ 6 | 7 | EXPOSE 8080 8 | 9 | CMD ["java", "-jar", "hello-service.jar"] -------------------------------------------------------------------------------- /hello-service/build.gradle: -------------------------------------------------------------------------------- 1 | plugins { 2 | id 'java' 3 | id 'org.springframework.boot' version '3.1.0' 4 | id 'io.spring.dependency-management' version '1.1.0' 5 | } 6 | 7 | apply plugin: "io.spring.dependency-management" 8 | 9 | group = "it.valeriovaudi" 10 | sourceCompatibility = "17" 11 | 12 | jar { 13 | archiveFileName = "hello-service" 14 | } 15 | 16 | repositories { 17 | mavenCentral() 18 | } 19 | 20 | ext { 21 | set('springCloudVersion', "2022.0.3") 22 | } 23 | 24 | dependencies { 25 | implementation "org.springframework.cloud:spring-cloud-starter-bootstrap" 26 | implementation "org.springframework.cloud:spring-cloud-starter-kubernetes-client-all" 27 | implementation "org.springframework.cloud:spring-cloud-starter-kubernetes-client-loadbalancer" 28 | 29 | implementation 'io.micrometer:micrometer-tracing-bridge-brave' 30 | runtimeOnly 'io.micrometer:micrometer-registry-prometheus' 31 | 32 | implementation "org.springframework.boot:spring-boot-starter-webflux" 33 | implementation "org.springframework.boot:spring-boot-starter-actuator" 34 | } 35 | 36 | dependencyManagement { 37 | imports { 38 | mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}" 39 | } 40 | } -------------------------------------------------------------------------------- /hello-service/gradle/wrapper/gradle-wrapper.jar: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/mrFlick72/spring-cloud-kubernetes-demo/ceb51f225246ca5ea808e5baef975b358ea86187/hello-service/gradle/wrapper/gradle-wrapper.jar -------------------------------------------------------------------------------- /hello-service/gradle/wrapper/gradle-wrapper.properties: -------------------------------------------------------------------------------- 1 | distributionBase=GRADLE_USER_HOME 2 | distributionPath=wrapper/dists 3 | distributionUrl=https\://services.gradle.org/distributions/gradle-7.6.1-bin.zip 4 | zipStoreBase=GRADLE_USER_HOME 5 | zipStorePath=wrapper/dists -------------------------------------------------------------------------------- /hello-service/gradlew: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | 3 | # 4 | # Copyright © 2015-2021 the original authors. 5 | # 6 | # Licensed under the Apache License, Version 2.0 (the "License");
