Jenkins构建、推送、拉取镜像和发布应用
这里本地的环境是
jenkins
192.168.2.3
harbor
192.168.2.6生产部署服务器 192.168.2.5
1. 安装 Publish Over SSH
插件
安装以下插件,可以实现远程发送Shell
命令
2. 配置远程部署服务器
1. 从jenkins
拷贝公钥到发布服务器
ssh-copy-id 192.168.2.5
2. 系统配置->添加远程服务器
应用,保存
Passphrase
:如果自己在本地生成的ssh key
没密码的话,这里不需要填写
Path to key
:这里填写私钥的地址
key
:这里填写私钥的内容(cat ~/.ssh/id_rsa
查看)
Name
:这里自己填写一个好记的名字
Hostname
:部署服务器主机ip
或者域名
Username
:部署服务器的用户名
Remote Directory
:远程的操作目录
3. 修改Jenkinsfile
构建脚本
生成远程调用模板代码
点击生成脚本
sshPublisher(publishers: [sshPublisherDesc(configName: ‘deploy_server‘, transfers: [sshTransfer(cleanRemote: false, excludes: ‘‘, execCommand: ‘‘, execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: ‘[, ]+‘, remoteDirectory: ‘‘, remoteDirectorySDF: false, removePrefix: ‘‘, sourceFiles: ‘‘)], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])
完整的Jenkinsfile
如下
//git凭证ID def git_auth = "cce455e2-ba69-459e-93bc-c58ce1e6278f" //git的url地址 def git_url = "ssh://:23456/itheima_group/tensquare_back.git" //镜像的版本号 def tag = "latest" //Harbor的url地址 def harbor_url = "192.168.2.6:85" //镜像库项目名称 def harbor_project = "tensquare" //Harbor的登录凭证ID def harbor_auth = " d6d9dbe8-f3c2-4cb0-bd79-770ea0b7d751" node { // 从gitlab拉取代码 stage(‘拉取代码‘) { checkout([$class: ‘GitSCM‘, branches: [[name: "*/${branch}"]], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]]) } stage(‘编译,安装公共子工程‘) { sh "mvn -f tensquare_common clean install" } stage(‘编译,构建镜像‘) { sh "mvn -f ${project_name} clean package dockerfile:build" //定义镜像名称 def imageName = "${project_name}:${tag}" //对镜像打上标签 sh "docker tag ${imageName} ${harbor_url}/${harbor_project}/${imageName}" //把镜像推送到Harbor withCredentials([usernamePassword(credentialsId: "${harbor_auth}", passwordVariable: ‘password‘, usernameVariable: ‘username‘)]) { //登录到Harbor sh "docker login -u ${username} -p ${password} ${harbor_url}" //镜像上传 sh "docker push ${harbor_url}/${harbor_project}/${imageName}" sh "echo 镜像上传成功" } //部署应用 sshPublisher(publishers: [sshPublisherDesc(configName: "deploy_server", transfers: [sshTransfer(cleanRemote: false, excludes: ‘‘, execCommand: "/opt/jenkins_shell/deploy.sh $harbor_url $harbor_project $project_name $tag $port ", execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: ‘[, ]+‘, remoteDirectory: ‘‘, remoteDirectorySDF: false, removePrefix: ‘‘, sourceFiles: ‘‘)], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)]) } }
上面的部署服务器的的deploy.sh
如下
#! /bin/sh #接收外部参数 harbor_url=$1 harbor_project_name=$2 project_name=$3 tag=$4 port=$5 imageName=$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 john -p John12345 $harbor_url # 下载镜像 docker pull $imageName # 启动容器 docker run -di -p $port:$port $imageName echo "容器启动成功"
将deploy.sh
脚本部署到部署服务器指定位置,并给与执行权限
3. 测试
这里做了
nat
端口转换,将虚拟机中的192.168.2.5:10086
转换到本地的10086端口
