Jenkins+Kubernetes+Docker完成微服务持续集成（书本刚翻到扉页，作者就说声再见。）

Jenkins+Kubernetes+Docker完成微服务持续集成

 

拉取代码，构建镜像

1） 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

 

 

 

2） 创建项目，编写构建Pipeline

 

tensquare_eureka_server@10086,tensquare_zuul@10020,tensquare_admin_service@9001,tensquare_gathering@9002

 

 

//配置harbor凭证

 

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}"

            }

        }

    }

}

}

 

注意：在构建过程会发现无法创建仓库目录，是因为NFS共享目录权限不足，需更改权限

mkdir  /opt/nfs/maven

chmod -R 777 /opt/nfs/maven

 

 

还有Docker命令执行权限问题

 

 

chmod 777 /var/run/docker.sock （在master节点，和起来Jenkins的pod节点的node）

 

 

 Eureka服务构建成功！！！
