1、下载 Kubernetes Continuous Deploy 插件

2、设置k8s凭证

在服务器里找到config文件

在凭证里面添加

获取k8s的id号

编写脚本文件

def git_address = "http://192.168.100.128:82/kgc/tensquare_back.git" 
def git_auth = "1162668b-deea-4c49-9a7d-eb7e6aec3ebe"
//构建版本的名称
def tag = "latest"
//Harbor私服地址
def harbor_url = "192.168.100.133:85"
//Harbor的项目名称
def harbor_project_name = "tensquare"
//Harbor的凭证
def harbor_auth = "4e2c8472-a8bf-4d51-912a-9a12ebdda722"
//k8s的凭证
def k8s_auth="9190e86a-b328-48ae-9d88-18bb2cb4644d"
//定义k8s-barbor的凭证
def secret_name="registry-auth-secret"

        containerTemplate(
            name: 'jnlp',
            image: "192.168.100.133:85/library/jenkins-slave-maven:latest"

        containerTemplate(

        ),
    ],

    // 第一步
    stage('pull code'){
        checkout([$class: 'GitSCM', branches: [[name: '*/master']], extensions: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_address}"]]])
    }
    // 第二步
    stage('make public sub project'){
        //编译并安装公共工程
        sh "mvn -f tensquare_common clean install"
    }
    // 第三步
    stage('make image'){
        //把选择的项目信息转为数组
        def selectedProjects = "${project_name}".split(',')
 
 
        for(int i=0;i<selectedProjects.size();i++){
            //取出每个项目的名称和端口
            def currentProject = selectedProjects[i];
            //项目名称
            def currentProjectName = currentProject.split('@')[0]
            //项目启动端口
            def currentProjectPort = currentProject.split('@')[1]
 
            //定义镜像名称
            def imageName = "${currentProjectName}:${tag}"
 
            //编译,构建本地镜像
            sh "mvn -f ${currentProjectName} clean package dockerfile:build"
            container('docker') {
 
                //给镜像打标签
                sh "docker tag ${imageName} ${harbor_url}/${harbor_project_name}/${imageName}"

                {
                    //登录
                    sh "docker login -u ${username} -p ${password} ${harbor_url}"
                    //上传镜像
                    sh "docker push ${harbor_url}/${harbor_project_name}/${imageName}"

            sh "docker rmi -f ${harbor_url}/${harbor_project_name}/${imageName}"
            }
            def deploy_image_name = "${harbor_url}/${harbor_project_name}/${imageName}"

                sed -i 's#\$IMAGE_NAME#${deploy_image_name}#' ${currentProjectName}/deploy.yml

            """
            kubernetesDeploy configs: "${currentProjectName}/deploy.yml", kubeconfigId: "${k8s_auth}"
        }
    }
}
}

3、在IDEA里配置文件

deploy.yml内容如下

---
apiVersion: v1
kind: Service
metadata:
  name: eureka
  labels:
    app: eureka
spec:
  type: NodePort
  ports:
    - port: 10086
      name: eureka
      targetPort: 10086
  selector:
    app: eureka
---
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: eureka
spec:
  serviceName: "eureka"
  replicas: 2
  selector:
    matchLabels:
      app: eureka
  template:
    metadata:
      labels:
        app: eureka
    spec:
      imagePullSecrets:
        - name: $SECRET_NAME
      containers:
        - name: eureka
          image: $IMAGE_NAME
          ports:
          - containerPort: 10086
          env:
          - name: MY_POD_NAME
            valueFrom:
             fieldRef:
              fieldPath: metadata.name
          - name: EUREKA_SERVER
            value: "http://eureka-0.eureka:10086/eureka/,http://eureka- 1.eureka:10086/eureka/"
          - name: EUREKA_INSTANCE_HOSTNAME
            value: ${MY_POD_NAME}.eureka
  podManagementPolicy: "Parallel"

在修改application.yml配置文件更改如下

server:
  port: ${PORT:10086}
spring:
  application:
    name: eureka

eureka:
  server:
    # 续期时间,即扫描失效服务的间隔时间(缺省为60*1000ms)
    eviction-interval-timer-in-ms: 5000
    enable-self-preservation: false
    use-read-only-response-cache: false
  client:
    # eureka client间隔多久去拉取服务注册信息 默认30s
    registry-fetch-interval-seconds: 5
    serviceUrl:
      defaultZone: ${EUREKA_SERVER:http://127.0.0.1:${server.port}/eureka/}
  instance:
    # 心跳间隔时间,即发送一次心跳之后,多久在发起下一次(缺省为30s)
    lease-renewal-interval-in-seconds: 5
    #  在收到一次心跳之后,等待下一次心跳的空档时间,大于心跳间隔即可,即服务续约到期时间(缺省为90s)
    lease-expiration-duration-in-seconds: 10
    instance-id: ${EUREKA_INSTANCE_HOSTNAME:${spring.application.name}}:${server.port}@${random.l ong(1000000,9999999)}
    hostname: ${EUREKA_INSTANCE_HOSTNAME:${spring.application.name}}

修改完成后,提交项目

这个时候构建会显示报错!!k8s访问harbor需要密钥权限

需要在所有的k8s主机上操作

[root@localhost ~]# docker login -u zch -p Zch12345 192.168.100.133:85     #先登录harbor仓库

在master主机上操作

[root@k8s-master ~]# kubectl create secret docker-registry registry-auth-secret --docker-server=192.168.100.133:85 --docker-username=zch --docker-password=Zch12345 --docker-email=zch@qq.com

在master节点查看

设置完成后开始构建

查看节点状态

[root@k8s-master ~]# kubectl get pods
NAME                                     READY   STATUS    RESTARTS   AGE
eureka-0                                 1/1     Running   0          7m28s
eureka-1                                 1/1     Running   0          7m28s
nfs-client-provisioner-6858cdf56-6ltmd   1/1     Running   0          169m

查看暴露的端口号

[root@k8s-master ~]# kubectl get service
NAME         TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)           AGE
eureka       NodePort    10.1.147.207   <none>        10086:30272/TCP   8m30s
kubernetes   ClusterIP   10.1.0.1       <none>        443/TCP           5h48m

访问两个node节点的30272端口

部署服务网关

更改配置文件中的eureka集群地址

修改服务网关zuul的地址

在zuul目录下创建配置文件deploy.yml如下

---
apiVersion: v1
kind: Service
metadata:
  name: zuul
  labels:
    app: zuul
spec:
  type: NodePort
  ports:
    - port: 10020
      name: zuul
      targetPort: 10020
  selector:
    app: zuul
---
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: zuul
spec:
  serviceName: "zuul"
  replicas: 2
  selector:
    matchLabels:
      app: zuul
  template:
    metadata:
      labels:
        app: zuul
    spec:
      imagePullSecrets:
        - name: $SECRET_NAME
      containers:
        - name: zuul
          image: $IMAGE_NAME
          ports:
            - containerPort: 10020
  podManagementPolicy: "Parallel"

需要手动上传父工程依赖到NFSMaven共享仓库目录中

提交项目

构建服务网关zuul

构建成功后查看

认证中心和活动微服务的构建方式与服务网关构建相同

[root@k8s-master ~]# kubectl get pods
NAME                                     READY   STATUS    RESTARTS   AGE

admin-1                                  1/1     Running   0          6m34s
eureka-0                                 1/1     Running   0          69m

zuul-1                                   1/1     Running   0          25m
