2.1 Jenkins創建流水線專案
比如創建任務名稱：pipeline的流水線專案，點擊確定
2.2 專案配置
點擊pipeline任務，點擊配置
1. 選擇scm，配置gitlab倉庫地址，這里要復制http的地址，
2. 勾選引數化構建程序，配置版本為傳參
3. 點擊流水線語法，會自動轉換成Jenkins腳本命令
三、流水線部署
3.1 在gitlab上創建一個Jenkins檔案
內容如下：
大概流程：從git倉庫拉取代碼-發送目標服務器-上傳鏡像到harbor-使用k8s部署業務
pipeline {
agent any
stages {
stage('從git倉庫拉取代碼') {
steps {
checkout([$class: 'GitSCM', branches: [[name: '*/xmzw']], extensions: [], userRemoteConfigs: [[credentialsId: '8f6e9bea-7734-43d8-a6a2-d54e233fa9ff', url: 'http://192.168.198.147/root/xmls.git']]])
echo 'H從git倉庫拉取代碼成功'
}
}
stage('發送目標服務器') {
steps {
sshPublisher(publishers: [sshPublisherDesc(configName: 'ssh', transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: '', execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: '[, ]+', remoteDirectory: '', remoteDirectorySDF: false, removePrefix: '', sourceFiles: '*tar.gz,*sh,*yaml')], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])
echo '發送目標服務器成功'
}
}
stage('上傳鏡像') {
steps {
sshPublisher(publishers: [sshPublisherDesc(configName: 'ssh', transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: '''ssh [email protected]
cd /usr/local/devops
sh harbor.sh $tag''', execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: '[, ]+', remoteDirectory: '', remoteDirectorySDF: false, removePrefix: '', sourceFiles: '')], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])
echo '上傳鏡像成功'
}
}
stage('部署業務') {
steps {
sshPublisher(publishers: [sshPublisherDesc(configName: 'ssh', transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: '''ssh [email protected]
cd /usr/local/devops
kubectl apply -f deploy.yaml
kubectl rollout restart -n my-ns-pipeline deployment my-deploy''', execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: '[, ]+', remoteDirectory: '', remoteDirectorySDF: false, removePrefix: '', sourceFiles: '')], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])
echo '部署業務成功'
}
}
}
}3.2 推送鏡像的腳本
[root@k8s-node2 xmls]# cat harbor.sh
#/bin/bash
imageTag=$1
echo > $imageTag
containerName=xm_nginx:${imageTag}
echo containerName: ${containerName}
cd /usr/local/devops
scp xm_nginx.tar.gz [email protected]:/usr/local/devops/
scp xm_nginx.tar.gz [email protected]:/usr/local/devops/
imageID=`docker images | grep xm_nginx |grep -v grep| awk '{print $3}'`
hostImageTag=`docker images | grep xm_nginx |grep -v grep| awk '{print $2}'`
echo imageID:$imageID hostImageTag:$hostImageTag
#洗掉舊鏡像
if [[ "$hostImageTag" =~ "$imageTag" ]] ; then
docker rmi -f ${imageID}
echo "Delete Image ${imageID} Success"
fi
#加載鏡像
docker load -i xm_nginx.tar.gz
echo "load Success"
#打標簽
docker tag xm_nginx:$imageTag 192.168.198.144:80/xmzw/xm_nginx:latest
docker login 192.168.198.144:80 -u admin -p Harbor12345
docker push 192.168.198.144:80/xmzw/xm_nginx:latest3.3 業務部署的yaml檔案
[root@k8s-node2 xmls]# cat deploy.yaml

spec:

xm_nginx.tar.gz為Nginx的1.23.1的鏡像包，網上下載一個即可
3.5 gitlab上創建tag
3.6 構建
選擇1.23.1，點擊構建
成功構建
3.7 測驗訪問正常
