gitlab+jenkins+harbor+k8s部署微服务-流水线自动部署
一、gitlab
1.1 登录gitlab创建项目
项目名称等自定义，权限可以选择私有或者公有
1.2 gitlab 代码提交
创建好的项目下复制项目地址
#在gitlab服务器上创建一个目录

bf35535..5455143 xmzw -> xmzw二、Jenkins
2.1 Jenkins创建流水线项目
比如创建任务名称：pipeline的流水线项目，点击确定
2.2 项目配置
点击pipeline任务，点击配置
1. 选择scm，配置gitlab仓库地址，这里要复制http的地址。
2. 勾选参数化构建过程，配置版本为传参
3. 点击流水线语法，会自动转换成Jenkins脚本命令
三、流水线部署
3.1 在gitlab上创建一个Jenkins文件
内容如下：
大概流程：从git仓库拉取代码-发送目标服务器-上传镜像到harbor-使用k8s部署业务
pipeline {
agent any
stages {
stage('从git仓库拉取代码') {
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从git仓库拉取代码成功'
}
}
stage('发送目标服务器') {
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 '发送目标服务器成功'
}
}
stage('上传镜像') {
steps {
sshPublisher(publishers: [sshPublisherDesc(configName: 'ssh', transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: '''ssh root@192.168.198.144
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 '上传镜像成功'
}
}
stage('部署业务') {
steps {
sshPublisher(publishers: [sshPublisherDesc(configName: 'ssh', transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: '''ssh root@192.168.198.144
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 '部署业务成功'
}
}
}
}3.2 推送镜像的脚本
[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 root@192.168.198.146:/usr/local/devops/
scp xm_nginx.tar.gz root@192.168.198.147:/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:$hostImageTag
#删除旧镜像
if [[ "$hostImageTag" =~ "$imageTag" ]] ; then
docker rmi -f ${imageID}
echo "Delete Image ${imageID} Success"
fi
#加载镜像
docker load -i xm_nginx.tar.gz
echo "load Success"
#打标签
docker tag xm_nginx:$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 业务部署的yaml文件
[root@k8s-node2 xmls]# cat deploy.yaml

xm_nginx.tar.gz为Nginx的1.23.1的镜像包，网上下载一个即可
3.5 gitlab上创建tag
3.6 构建
选择1.23.1，点击构建
成功构建
3.7 测试访问正常
