Specifying instances by host and port like this however may preclude you from being able to effectively loadbalance requests. 6 | 7 | The provided message broker is RabbitMQ, however it's possible to swap out the RabbitMQ server for the provided ActiveMQ server. 8 | 9 | ## Project Structure 10 | - `eureka` 11 | - Spring Cloud Netflix Eureka - provides service discovery for enabled clients. This allows our applications to find each other by their `spring.application.name` property and the port they are configured to run on. With this our services can make requests to discoverable services with `http://my-service-name` rather than needing to know the hostname and port of the service 12 | - `gateway` 13 | - Spring Cloud Gateway - provides routing and load balancing for HTTP and Websocket connections through a single host and port (http://localhost:8080 as configured), and uses service discovery to route requests by service name. 14 | - `server` 15 | - Our example application which is serving a websocket endpoint for our client to connect to. This application has two profiles configured, a default profile running on port 8081 and a second profile on port 8082. 16 | - `example.html` 17 | - Our example "client" to connect to our websocket server. 18 | 19 | ## Requirements 20 | - Docker 21 | - Web browser 22 | 23 | ## Running 24 | ### Using Docker Compose: 25 | - Run `docker-compose up -d` to build and start the containers 26 | - Access Eureka console via http://localhost:8761 or health via http://localhost:8761/actuator/health 27 | - Access Gateway and application endpoints through http://localhost:8080, or health via http://localhost:8080/actuator/health 28 | - NOTE: There is no default route 29 | - open `example.html` in a websocket compatible browser 30 | 31 | During startup be patient as eureka attempts to resolve location and port, as well as health for each of the discovery enabled applications (gateway, server [app1], and server [app2]). This could take some time for the discovery server and clients to begin accepting requests. 32 | 33 | I've added a timed method to respond to the same websocket topic which the client is subscribed to to simulate push notifications from the server, either in response to a system action or in response to another user's action. 34 | 35 | ### Demonstration of the project running 36 | ![Websocket demonstration](https://github.com/jmlw/demo-projects/blob/master/spring-cloud-gateway-websocket/ws-demo-1.gif?raw=true) 37 | 38 | ### Demonstration with second user in another window 39 | ![Websocket demonstration with second user](https://github.com/jmlw/demo-projects/blob/master/spring-cloud-gateway-websocket/ws-demo-2.gif?raw=true) 40 | -------------------------------------------------------------------------------- /spring-cloud-gateway-websocket/docker-compose.yml: -------------------------------------------------------------------------------- 1 | version: '3' 2 | 3 | services: 4 | rabbitmq: 5 | build: rabbitmq 6 | labels: 7 | kompose.service.type: nodeport 8 | ports: 9 | - '15672:15672' 10 | volumes: 11 | - 'rabbitmq_data:/bitnami' 12 | 13 | eureka: 14 | build: ./eureka 15 | ports: 16 | - '8761:8761' 17 | 18 | gateway: 19 | build: ./gateway 20 | ports: 21 | - '8080:8080' 22 | depends_on: 23 | - eureka 24 | environment: 25 | - EUREKA_URI=http://eureka:8761/eureka 26 | 27 | websocket-server-1: 28 | build: ./websocket-server 29 | depends_on: 30 | - eureka 31 | - rabbitmq 32 | environment: 33 | - EUREKA_URI=http://eureka:8761/eureka 34 | - BROKER_RELAY_HOST=rabbitmq 35 | 36 | websocket-server-2: 37 | build: ./websocket-server 38 | depends_on: 39 | - eureka 40 | - rabbitmq 41 | environment: 42 | - EUREKA_URI=http://eureka:8761/eureka 43 | - BROKER_RELAY_HOST=rabbitmq 44 | 45 | volumes: 46 | rabbitmq_data: 47 | driver: local 48 | -------------------------------------------------------------------------------- /spring-cloud-gateway-websocket/eureka/.mvn/wrapper/maven-wrapper.properties: -------------------------------------------------------------------------------- 1 | distributionUrl=https://repo.maven.apache.org/maven2/org/apache/maven/apache-maven/3.5.4/apache-maven-3.5.4-bin.zip 2 | -------------------------------------------------------------------------------- /spring-cloud-gateway-websocket/eureka/Dockerfile: -------------------------------------------------------------------------------- 1 | FROM maven:3-jdk-8-alpine AS build 2 | WORKDIR /opt/src 3 | COPY pom.xml . 4 | RUN mvn dependency:go-offline 5 | COPY src src 6 | RUN mvn package -Dmaven.test.skip=true spring-boot:repackage 7 | 8 | FROM openjdk:8-jre-alpine 9 | COPY --from=build /opt/src/target/eureka-0.0.1-SNAPSHOT.jar /opt/app.jar 10 | ENTRYPOINT ["java","-jar","/opt/app.jar"] 11 | -------------------------------------------------------------------------------- /spring-cloud-gateway-websocket/eureka/mvnw: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | # ---------------------------------------------------------------------------- 3 | # Licensed to the Apache Software Foundation (ASF) under one 4 | # or more contributor license agreements.

Refer to the [official documentation on configuring a pod with cofigmaps](https://kubernetes.io/docs/tasks/configure-pod-container/configure-pod-configmap/) for additional information including [how to set up minikube](https://kubernetes.io/docs/setup/learning-environment/minikube/) or use an alternative. 7 | 8 | Also ensure you have Maven and Java 8 installed. Some tweaks to dependencies may be required for Java 9+ since `java.xml.bind ` was removed in later versions of Java. 9 | 10 | ## Build 11 | We will be utilizing minikube, and minikube's build environment to facilitate this demo, however it's possible to use the `latest` version of the demo app from [my docker hub](https://cloud.docker.com/u/jmlw/repository/list). In your terminal run `eval $(minikube docker-env)` to configure your current session to use minikube's docker engine to build and store images. This is required if you intend to use local images only. Otherwise, the `PullPolicy` in the kubernetes deployment can be changed to `Always` and an image from a remote docker repository can be used. 12 | 13 | Maven is configured to build the docker image using the packaged jar by running: 14 | ```bash 15 | ./mvnw clean compile package dockerfile:build 16 | ``` 17 | 18 | ## Deploy to (Mini)Kubernetes 19 | To deploy, ensure you kubectl configured, and simply run `kubectl apply -f deployments/`. This will apply all of the manifest files in the directory: 20 | 21 | - service account for the container 22 | - role defining kubenertes API access levels 23 | - role binding to attache the role to the service account 24 | - deployment defining a template for the pod(s) to be created utilizing the image we've built 25 | - service to expose our app as a NodePort in our Kuberentes Cluster 26 | - configmap for our application which includes an override for the default value provided in our spring boot application.yml 27 | 28 | ## Verify 29 | Verify that our app is actually using the configuration from our configmap, fetch the logs of our pod as a one liner: 30 | 31 | ```bash 32 | kubectl logs "$(kubectl get pods | grep demo-deployment | awk '{print $1}')" 33 | ``` 34 | 35 | Now verify that our endpoint is accessible and returns our config value: 36 | 37 | ```bash 38 | curl "$(minikube service demo --url)" 39 | # expected output: 40 | # Configuration from Kubernetes! 41 | ``` 42 | -------------------------------------------------------------------------------- /spring-cloud-kubernetes-config-demo/deployments/configmap.yaml: -------------------------------------------------------------------------------- 1 | apiVersion: v1 2 | kind: ConfigMap 3 | metadata: 4 | # matches the spring app name as defined in application.yml 5 | name: spring-cloud-kubernetes-config-demo 6 | data: 7 | # must be named 'application.yaml' or be the only key in this config 8 | # refer to Spring Cloud Kubernetes Config documentation or source code 9 | application.yaml: |- 10 | app: 11 | config: Configuration from Kubernetes! 12 | 13 | --- 14 | apiVersion: v1 15 | kind: ConfigMap 16 | metadata: 17 | name: environment-variable-config 18 | data: 19 | ENVIRONMENT_CONFIG: Configuration from Docker environment in Kubernetes! 20 | -------------------------------------------------------------------------------- /spring-cloud-kubernetes-config-demo/deployments/deployment.yaml: -------------------------------------------------------------------------------- 1 | apiVersion: rbac.authorization.k8s.io/v1 2 | kind: Role 3 | metadata: 4 | namespace: default 5 | name: demo-role 6 | rules: 7 | - apiGroups: [""] # "" indicates the core API group 8 | resources: ["pods", "configmaps"] 9 | verbs: ["get", "watch", "list"] 10 | 11 | --- 12 | apiVersion: rbac.authorization.k8s.io/v1beta1 13 | kind: RoleBinding 14 | metadata: 15 | name: demo-role-binding 16 | namespace: default 17 | subjects: 18 | - kind: ServiceAccount 19 | name: demo-service-account 20 | namespace: default 21 | roleRef: 22 | kind: Role 23 | name: demo-role 24 | apiGroup: rbac.authorization.k8s.io 25 | 26 | --- 27 | apiVersion: v1 28 | kind: ServiceAccount 29 | metadata: 30 | name: demo-service-account 31 | namespace: default 32 | 33 | --- 34 | apiVersion: apps/v1 35 | kind: Deployment 36 | metadata: 37 | name: demo-deployment 38 | labels: 39 | app: demo 40 | spec: 41 | replicas: 1 42 | selector: 43 | matchLabels: 44 | app: demo 45 | template: 46 | metadata: 47 | labels: 48 | app: demo 49 | spec: 50 | serviceAccountName: demo-service-account 51 | containers: 52 | - name: spring-cloud-kubernetes-config-demo 53 | image: jmlw/spring-cloud-kubernetes-config-demo 54 | imagePullPolicy: Never 55 | ports: 56 | - containerPort: 8080 57 | env: 58 | - name: ENVIRONMENT_CONFIG 59 | valueFrom: 60 | configMapKeyRef: 61 | name: environment-variable-config 62 | key: ENVIRONMENT_CONFIG 63 | --- 64 | kind: Service 65 | apiVersion: v1 66 | metadata: 67 | name: demo 68 | spec: 69 | selector: 70 | app: demo 71 | ports: 72 | - protocol: TCP 73 | port: 8080 74 | nodePort: 30000 75 | name: http 76 | type: NodePort 77 | -------------------------------------------------------------------------------- /spring-cloud-kubernetes-config-demo/mvnw: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | # ---------------------------------------------------------------------------- 3 | # Licensed to the Apache Software Foundation (ASF) under one 4 | # or more contributor license agreements.
