基于kubernetes平台微服务的部署

基于kubernetes平台微服务的部署

首先下载插件：

kubernetes Continuous Deploy

然后去找 .kube/ 里的config 复制里面的内容

去添加凭据：

然后就是脚本更新：

def git_address = "http://20.0.0.20:82/root/tensquare_back.git"
def git_auth = "904eff5d-41c8-44ad-ba24-7f539a0edb96"
//构建版本的名称
def tag = "latest"
//Harbor私服地址
def harbor_url = "20.0.0.50:85"
//Harbor的项目名称
def harbor_project_name = "tensquare"
//Harbor的凭证
def harbor_auth = "427399a8-db35-48e8-b5cf-a1ea63f10cc5"
//k8s的凭证
def k8s_auth="4f3c9e60-da07-49b3-89ae-d708516e8071"
//定义k8s-barbor的凭证
def secret_name="registry-auth-secret"
 
podTemplate(label: 'jenkins-slave', cloud: 'kubernetes', containers: [
        containerTemplate(
            name: 'jnlp',
            image: "20.0.0.50:85/library/jenkins-slave-maven:latest"
        ),
        containerTemplate(
            name: 'docker',
            image: "docker:stable",
            ttyEnabled: true,
            command: 'cat'
        ),
    ],
    volumes: [
        hostPathVolume(mountPath: '/var/run/docker.sock', hostPath: '/var/run/docker.sock'),
        nfsVolume(mountPath: '/usr/local/apache-maven/repo', serverAddress: '20.0.0.10' , serverPath: '/opt/nfs/maven'),
    ],
)
{
node("jenkins-slave"){
    // 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Harbor，并上传镜像
                withCredentials([usernamePassword(credentialsId: "${harbor_auth}", passwordVariable: 'password', usernameVariable: 'username')])
                {
                    //登录
                    sh "docker login -u ${username} -p ${password} ${harbor_url}"
                    //上传镜像
                    sh "docker push ${harbor_url}/${harbor_project_name}/${imageName}"
                }
 
            //删除本地镜像
            sh "docker rmi -f ${imageName}"
            sh "docker rmi -f ${harbor_url}/${harbor_project_name}/${imageName}"
            }
            def deploy_image_name = "${harbor_url}/${harbor_project_name}/${imageName}"
            //部署到K8S
            sh """
                sed -i 's#\$IMAGE_NAME#${deploy_image_name}#' ${currentProjectName}/deploy.yml
                sed -i 's#\$SECRET_NAME#${secret_name}#' ${currentProjectName}/deploy.yml
            """
            kubernetesDeploy configs: "${currentProjectName}/deploy.yml", kubeconfigId: "${k8s_auth}"
        }
    }
}
}

　　

要更改的就是：

添加k8s的凭证：

然后在eureka 目录下创建deploy文件：

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"

　　

里面的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}}

　

然后在提交前在k8s所有主机上操作

docker login -u lvbu -p Lvbu1234 20.0.0.50:85

kubectl create secret docker-registry registry-auth-secret --docker-server=20.0.0.50:85 --docker-username=lvbu --docker-password=Lvbu1234 -- docker-email=lbu@qq.com

　　

然后去提交之前的修改的配置

提交完之后就可以构建了！

然后去查看：

kubectl get secrets

kubectl get pods

kubectl get servicef  查看能看到端口 访问node节点的端口  就会发现注册中心有了　

然后部署服务网关：

同理更改配置文件中的eureka集群地址：

http://eureka-0.eureka:10086/eureka/,http://eureka- 1.eureka:10086/eureka/　

所有的都要更改！

然后一样的操作在网关低下创建deploy.yml文件：

内容如下：

---
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"

　　

在提交前先去手动上传父工程依赖到NFS的maven共享仓库目录中：

　　

然后在构建！

然后就是部署admin_service：

也是创建deploy.yml：

---
apiVersion: v1
kind: Service
metadata:
  name: admin
  labels:
    app: admin
spec:
  type: NodePort
  ports:
    - port: 9001
      name: admin
      targetPort: 9001
  selector:
    app: admin
---
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: admin
spec:
  serviceName: "admin"
  replicas: 2
  selector:
    matchLabels:
      app: admin
  template:
    metadata:
      labels:
        app: admin
    spec:
      imagePullSecrets:
        - name: $SECRET_NAME
      containers:
        - name: admin
          image: $IMAGE_NAME
          ports:
            - containerPort: 9001
  podManagementPolicy: "Parallel"

　　

然后 集群地址也要更改！

接下来的部署gatjering  也是如此：

deploy.yml文件如下：

---
apiVersion: v1
kind: Service
metadata:
  name: gathering
  labels:
    app: gathering
spec:
  type: NodePort
  ports:
    - port: 9002
      name: gathering
      targetPort: 9002
  selector:
    app: gathering
---
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: gathering
spec:
  serviceName: "gathering"
  replicas: 2
  selector:
    matchLabels:
      app: gathering
  template:
    metadata:
      labels:
        app: gathering
    spec:
      imagePullSecrets:
        - name: $SECRET_NAME
      containers:
        - name: gathering
          image: $IMAGE_NAME
          ports:
            - containerPort: 9002
  podManagementPolicy: "Parallel"

　　

也要修改集群地址eureka！

然后就可以一次性提交代码然后一次性构建！

结果如下：
