因为之前写过基于K8S部署jenkins master/slave平台，在这个的基础上构建微服务到K8S集群中
回到顶部## Jenkins-slave构建微服务项目到K8S集群
1、微服务项目上传到git仓库
这个就不多说了
2、更改注册中心eureka的配置文件
进入到项目代码中，更改微服务中eureka-service的配置文件application.yaml（需要和开发对一下，具体还要加哪些参数）
| 123456789101112131415 | server:``port: 8761``spring: application: name: eureka-service eureka:``instance:``prefer-ip-address: false``client:``region: default``service-url:``defaultZone: http:``//eureka-0.eureka.default:${server.port}/eureka/,http://eureka-1.eureka.default:${server.port}/eureka/``register-with-eureka: true``fetch-registry: true |
其他应用程序往eureka注册，需要在各自的application.yaml里添加下面的eureka信息
| 123456789 | eureka:``instance:``prefer-ip-address: false``client:``region: default``service-url:``defaultZone: http:``//eureka-0.eureka:8761/eureka/,http://eureka-1.eureka:8761/eureka/``register-with-eureka: true``fetch-registry: true |
3、创建statefulset资源文件部署eureka，ingress做负载均衡
（将所以要创建的资源都合并到一个yaml文件，上传到git仓库 项目代码的eureka目录下）
| 1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253545556575859606162636465 | #创建Service为headless``apiVersion: v1``kind: Service``metadata:``namespace``: NS``labels:``app: eureka``name: eureka``spec:``clusterIP: None``selector:``app: eureka``ports:``- port: 8761``protocol: TCP``targetPort: 8761``status:``loadBalancer: {} ---``#创建StatefulSet``apiVersion: apps/v1``kind: StatefulSet``metadata:``name: eureka``namespace``: NS``spec:``selector:``matchLabels:``app: eureka``serviceName: "eureka"``replicas: RSCOUNT``template:``metadata:``labels:``app: eureka``spec:``imagePullSecrets:``- name: SECRET_NAME``containers:``- name: eureka``image: IMAGE_NAME``ports:``- containerPort: 8761 ---``#创建ingress``apiVersion: networking.k8s.io/v1``kind: Ingress``metadata:``name: eureka-ingress``annotations:``kubernetes.io/ingress.``class``: "nginx"``spec:``rules:``- host: eureka.test.com``http:``paths:``- path: /``pathType: Prefix``backend:``service:``name: eureka``port: number: 8761 |
4、在jenkins创建流水线任务
新建任务——eureka 流水线——然后进入项目配置，Jenkinsfile如下：
| 123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102103104105106107108109110111112113114115116117118119 | def registry = "10.48.14.50:8888"``def project = "dev"``def app_name = "eureka-service"``def jar_path = "build/libs"``def jar_name = "${app_name}-0.0.1-SNAPSHOT.jar"``def jar_port = "8761"``def image_name = "${registry}/${project}/${app_name}:${BUILD_NUMBER}"``def git_address = "http://10.48.14.100:30080/001/xiangmu.git"``// 认证``def secret_name = "registrypullauth"``def docker_registry_auth = "b07ed5ba-e191-4688-9ed2-623f4753781c"``def git_auth = "a5ec87ae-87a1-418e-aa49-53c4aedcd261"``def k8s_auth = "3cd3f414-a0e2-4bc0-8808-78c64e6ad7d2"``def JAVA_OPTS = "-Xms128m -Xmx256m -Dfile.encoding=UTF8 -Duser.timezone=GMT+08 -Dspring.profiles.active=test" pipeline {``agent {``kubernetes {``label "jenkins-slave"``yaml ""``"``kind: Pod``metadata:``name: jenkins-slave``spec:``containers:``- name: jnlp``image: "${registry}/library/jenkins-slave-jdk:latest"``imagePullPolicy: Always``env: - name: TZ``value: Asia/Shanghai``volumeMounts:``- name: docker-cmd``mountPath: /usr/bin/docker``- name: docker-sock``mountPath: /``var``/run/docker.sock``- name: gradle-cache``mountPath: /root/.gradle``volumes:``- name: docker-cmd``hostPath:``path: /usr/bin/docker``- name: docker-sock``hostPath:``path: /``var``/run/docker.sock``- name: gradle-cache``hostPath: path: /tmp/gradle``""``"``}``}``parameters {``choice (choices: [``'1'``, '2'``, '3'``, '5'``, '7'``], description: '副本数'``, name: 'ReplicaCount'``)``choice (choices: [``'dev'``,``'test'``,``'prod'``,``'default'``], description: '命名空间'``, name: 'Namespace'``)``}``stages {``stage(``'拉取代码'``){``steps {``checkout([$``class``: 'GitSCM'``, branches: [[name: "${params.Branch}"``]], doGenerateSubmoduleConfigurations: false``, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${git_auth}"``, url: "${git_address}"``]]``])``}``} stage(``'代码编译'``){``steps {``sh ""``"``java -version``pwd``cd ${app_name}``pwd``gradle -v``gradle clean build -x test``""``" }``} stage(``'构建镜像'``){``steps {``withCredentials([usernamePassword(credentialsId: "${docker_registry_auth}"``, passwordVariable: 'password'``, usernameVariable: 'username'``)]) {``sh ""``"``echo '``FROM ${registry}/library/java:11``MAINTAINER liang``RUN apk add -U tzdata && \``ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime``ADD ${jar_path}/${jar_name} /``EXPOSE ${jar_port}``CMD java -jar $JAVA_OPTS /${jar_name}``'> ${app_name}/Dockerfile``docker build -t ${image_name} ${app_name}``docker login -u ${username} -p ${password} ${registry}``docker push ${image_name}``""``"``}``} } stage(``'部署到K8S平台'``){``steps {``configFileProvider([configFile(fileId: "${k8s_auth}"``, targetLocation: 'admin.kubeconfig'``)]) {``sh ""``"``pwd``sed -i 's#IMAGE_NAME#${image_name}#' ${app_name}/deploy.yaml``sed -i 's#SECRET_NAME#${secret_name}#' ${app_name}/deploy.yaml``sed -i 's#RSCOUNT#${ReplicaCount}#' ${app_name}/deploy.yaml``sed -i 's#NS#${Namespace}#' ${app_name}/deploy.yaml``kubectl apply -f ${app_name}/deploy.yaml -n ${Namespace} --kubeconfig=admin.kubeconfig``sleep 10``kubectl get pod -n ${Namespace} --kubeconfig=admin.kubeconfig``""``"``}``}``}``}``} |
构建项目：可以选择启动的副本数、项目代码分支、k8s命名空间（dev、test、prod：代表开发、测试、生产环境）
查看构建日志：
浏览器访问eureka：
需要添加dns记录或者host文件(根据自己的实际情况添加)
http://eureka.test.com 
5、构建其他应用程序部署到K8S
修改微服务网关gateway的配置文件application.yaml：
| 123456789101112131415 | server:``port: 8130``spring: application: name: gateway-service eureka:``instance:``prefer-ip-address: false``client:``region: default``service-url:``defaultZone: http:``//eureka-0.eureka:8761/eureka/,http://eureka-1.eureka:8761/eureka/``register-with-eureka: true``fetch-registry: true |
创建deploy资源 部署gateway，ingress做负载均衡
| 123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960 | apiVersion: v1``kind: Service``metadata:``namespace``: NS``labels:``app: gateway``name: gateway``spec:``selector:``app: gateway``ports:``- port: 8130``protocol: TCP``targetPort: 8130``status:``loadBalancer: {}``---``#创建Deployment``apiVersion: apps/v1``kind: Deployment``metadata:``name: gateway``namespace``: NS``spec:``selector: matchLabels:``app: gateway``replicas: RSCOUNT``template:``metadata:``labels:``app: gateway``spec:``imagePullSecrets:``- name: SECRET_NAME``containers:``- name: gateway``image: IMAGE_NAME``ports:``- containerPort: 8130``---``#创建ingress``apiVersion: networking.k8s.io/v1``kind: Ingress``metadata:``name: gateway-ingress``annotations:``kubernetes.io/ingress.``class``: "nginx"``spec:``rules:``- host: gateway.test.com``http:``paths:``- path: /``pathType: Prefix``backend:``service:``name: gateway``port: number: 8130 |
jenkins中创建gateway项目，使用eureka的Jenkinsfile，只需要修改其中的变量就可以了，这里就不写了
…
应用程序构建完成后，查看是否注册到eureka：
再查看eureka日志，说明成功了
大概就是这样，部署微服务的其他应用程序也是一样。
需要注意的是：项目中application.yaml的参数要问开发人员（有些程序需要连数据库）
