一、编写Jenkinsfile

基于之前的Jenkinsfile进行修改

//git的凭证
def git_auth="520d10cb-e95e-48d5-8b84-ca1be098d23f"
//git的URL
def git_url="git@192.168.72.14:emotional-damage/tensquare_back.git"
//镜像标签
def tag="latest"
//harbor的url地址
def harbor_url="192.168.72.16:85"
//镜像仓库名
def harbor_name="tensquare"
//harbor凭证
def harbor_auth="5fe03d24-0156-4497-96b5-c0a7ce6564f1"
node {
     //获取当前选择项目名称
     def selectedProjectNames="${project_name}".split(",")
     //获取当前选择的服务器
     def selectedServers="${publish_server}".split(",")
     stage('拉取代码') {
            //用变量代替，字符串符号使用双引号
            checkout([$class: 'GitSCM', branches: [[name: '*/${branch}']], extensions: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
     }
     stage('审查代码') {
            for(int i=0;i<selectedProjectNames.length;i++){
                //项目信息 tensquare_eureka_server@10086
                def projectInfo=selectedProjectNames[i]
                //当前的项目名称
                def currentProjectName="${projectInfo}".split("@")[0]
                //当前窗口的项目端口
                def currentProjectPort="${projectInfo}".split("@")[1]
                //定义SonarQubeScanner工具
                def scannerHome = tool 'sonar-scanner'
                //引用SonarQube系统环境
                withSonarQubeEnv('sonarqube') {
                sh """
                cd ${currentProjectName}
                ${scannerHome}/bin/sonar-scanner
                """
                }
            }
     }
     stage('编译打包工具服务') {
            sh  "mvn -f tensquare_common clean install"
     }
     stage('打包其他子服务') {
            for(int i=0;i<selectedProjectNames.length;i++){
                //项目信息 tensquare_eureka_server@10086
                def projectInfo=selectedProjectNames[i]
                //当前的项目名称
                def currentProjectName="${projectInfo}".split("@")[0]
                //当前窗口的项目端口
                def currentProjectPort="${projectInfo}".split("@")[1]
                sh  "mvn -f ${currentProjectName} clean package dockerfile:build"
                //定义镜像名称
                def imageName="${currentProjectName}:${tag}"
                //对镜像打标签
                sh "docker tag ${imageName} ${harbor_url}/${harbor_name}/${imageName}"
                withCredentials([usernamePassword(credentialsId: '5fe03d24-0156-4497-96b5-c0a7ce6564f1', passwordVariable: 'password', usernameVariable: 'username')]) {
                // some block
                //登录harbor
                sh "docker login -u ${username} -p ${password} ${harbor_url}"
                //镜像上传
                sh "docker push ${harbor_url}/${harbor_name}/${imageName}"
                sh "echo 镜像上传成功"
                }
                    //遍历所有服务器，分别部署
                    for(int j=0;j<selectedServers.length;j++){
                    //获取当前遍历的服务器名称
                    def currentServerName = selectedServers[j]

                    //加上的参数格式：--spring.profiles.active=eureka-server1/eureka-server2
                    def activeProfile = "--spring.profiles.active="

                    //根据不同的服务名称来读取不同的Eureka配置信息
                    if(currentServerName=="master_server"){
                    activeProfile = activeProfile+"eureka-server1"
                    }else if(currentServerName=="slave_server"){
                    activeProfile = activeProfile+"eureka-server2"
                    }
                    //部署应用
                    sshPublisher(publishers: [sshPublisherDesc(configName: "${currentServerName}", transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: "/opt/jenkins_shell/deployCluster.sh ${harbor_url} ${harbor_name} ${currentProjectName} ${tag} ${currentProjectPort} ${activeProfile}", execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: '[, ]+', remoteDirectory: '', remoteDirectorySDF: false, removePrefix: '', sourceFiles: '')], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])
                    }
            }
     }
}

写好之后推送到Gitlab上

二、编写Docker容器脚本

这个Docker集群的脚本，主服务器和从服务器都要有deployCluster.sh脚本

放在/opt/Jenkins_shell目录下，别忘了给执行权限 chmod +x

mkdir /opt/jenkins_shell

vim /opt/Jenkins_shell/deployCluster.sh

#! /bin/sh
#接收外部参数
harbor_url=$1
harbor_project_name=$2
project_name=$3
tag=$4
port=$5
profile=$6
imageName=$harbor_url/$harbor_project_name/$project_name:$tag
echo "$imageName"
#查询容器是否存在，存在则删除
containerId=`docker ps -a | grep -w ${project_name}:${tag}  | awk '{print $1}'`
if [ "$containerId" !=  "" ] ; then
    #停掉容器
    docker stop $containerId
    #删除容器
    docker rm $containerId
        echo "成功删除容器"
fi
#查询镜像是否存在，存在则删除
imageId=`docker images | grep -w $project_name  | awk '{print $3}'`
if [ "$imageId" !=  "" ] ; then
    #删除镜像
    docker rmi -f $imageId
        echo "成功删除镜像"
fi
# 登录Harbor
docker login -u bigsun -p Tt87654321 $harbor_url
# 下载镜像
docker pull $imageName
# 启动容器
docker run -di -p $port:$port $imageName $profile
echo "容器启动成功"

o "容器启动成功"
