Jenkins構建、推送、拉取鏡像和發布應用

本文轉載自查看原文 2020-05-16 17:47 1491 Jenkins

這里本地的環境是

jenkins 192.168.2.3

harbor 192.168.2.6

生產部署服務器 192.168.2.5

1. 安裝 `Publish Over SSH` 插件

安裝以下插件，可以實現遠程發送Shell命令

2. 配置遠程部署服務器

1. 從`Jenkins`拷貝公鑰到發布服務器

ssh-copy-id 192.168.2.5

2. 系統配置->添加遠程服務器

應用，保存

Passphrase:如果自己在本地生成的ssh key沒密碼的話，這里不需要填寫

Path to key:這里填寫私鑰的地址

key：這里填寫私鑰的內容（cat ~/.ssh/id_rsa查看）

Name：這里自己填寫一個好記的名字

Hostname：部署服務器主機ip或者域名

Username：部署服務器的用戶名

Remote Directory:遠程的操作目錄

3. 修改`Jenkinsfile`構建腳本

生成遠程調用模板代碼

點擊生成腳本

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憑證ID
def git_auth = "cce455e2-ba69-459e-93bc-c58ce1e6278f"
//git的url地址
def git_url = "ssh://git@192.168.2.4:23456/itheima_group/tensquare_back.git"
//鏡像的版本號
def tag = "latest"
//Harbor的url地址
def harbor_url = "192.168.2.6:85"
//鏡像庫項目名稱
def harbor_project = "tensquare"
//Harbor的登錄憑證ID
def harbor_auth = "	d6d9dbe8-f3c2-4cb0-bd79-770ea0b7d751"

node {
    // 從gitlab拉取代碼
   stage('拉取代碼') {
      checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
   }
   stage('編譯，安裝公共子工程') {
      sh "mvn -f tensquare_common clean install"
   }
   stage('編譯，構建鏡像') {
       sh "mvn -f ${project_name} clean package dockerfile:build"

       //定義鏡像名稱
       def imageName = "${project_name}:${tag}"

       //對鏡像打上標簽
       sh "docker tag ${imageName} ${harbor_url}/${harbor_project}/${imageName}"

       //把鏡像推送到Harbor
       withCredentials([usernamePassword(credentialsId: "${harbor_auth}", passwordVariable: 'password', usernameVariable: 'username')]) {

           //登錄到Harbor
           sh "docker login -u ${username} -p ${password} ${harbor_url}"

           //鏡像上傳
           sh "docker push ${harbor_url}/${harbor_project}/${imageName}"

           sh "echo 鏡像上傳成功"
       }

       //部署應用
       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)])
   }
}

上面的部署服務器的的deploy.sh如下

#! /bin/sh
#接收外部參數
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"

#查詢容器是否存在，存在則刪除
containerId=`docker ps -a | grep -w ${project_name}:${tag}  | awk '{print $1}'`
if [ "$containerId" !=  "" ] ; then
    #停掉容器
    docker stop $containerId

    #刪除容器
    docker rm $containerId
	
	echo "成功刪除容器"
fi

#查詢鏡像是否存在，存在則刪除
imageId=`docker images | grep -w $project_name  | awk '{print $3}'`

if [ "$imageId" !=  "" ] ; then
      
    #刪除鏡像
    docker rmi -f $imageId
	
	echo "成功刪除鏡像"
fi

# 登錄Harbor
docker login -u john -p John12345 $harbor_url

# 下載鏡像
docker pull $imageName

# 啟動容器
docker run -di -p $port:$port $imageName

echo "容器啟動成功"

將deploy.sh腳本部署到部署服務器指定位置，並給與執行權限
