1、创建一个流水线的新项目

2、创建NFS共享目录

让所有Jenkins-Slave构建指向NFS的Maven的共享仓库目录

[root@k8s-master ~]# vim /etc/exports
/opt/nfs/jenkins *(rw,no_root_squash)
/opt/nfs/maven *(rw,no_root_squash)     
[root@k8s-master ~]# systemctl restart nfs

3、项目里配置参数

4、配置harbor凭证

5、编写构建Pipeline

粘贴以下模板，参数自行修改 ！！！

def git_address = "http://192.168.195.180:82/kgc_group/tensquare_back.git" 
def git_auth = "f06c4b06-ac26-4683-ad00-2d3599c827ee"
//构建版本的名称
def tag = "latest"
//Harbor私服地址
def harbor_url = "192.168.195.183:85"
//Harbor的项目名称
def harbor_project_name = "tensquare"
//Harbor的凭证
def harbor_auth = "46c4a44a-65d7-419f-a34b-9dd0a25710c9"



podTemplate(label: 'jenkins-slave', cloud: 'kubernetes', containers: [ 
        containerTemplate(
            name: 'jnlp',
            image: "192.168.195.183:85/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: '192.168.195.200' , 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}"
            }
        }
    }
}
}

在构建中需要创建仓库目录，是因为NFS共享目录权限不足，需更改权限

[root@k8s-master ~]# mkdir -p /opt/nfs/maven
[root@k8s-master ~]# chmod -R 777 /opt/nfs/maven/

还需要在从节点设置docker命令权限

[root@k8s-node1 ~]# chmod 777 /var/run/docker.sock
[root@k8s-node2 ~]# chmod 777 /var/run/docker.sock

6、开始构建项目

Eureka服务构建成功！！！
