安装Gitlab

参考这篇文章：

blog.51cto.com/bigboss/212…

• Docker方式安装：
  

github.com/JyBigBoss/d…

• 安装Harbor
  
• blog.51cto.com/bigboss/231…
• docker 配https registry私有仓库的重点说明
  

• 生成ca 证书 给harbor 使用

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ./server.key -out ./server.crt -subj "/CN=registry.lotbrick.com"

复制docker 客户端登入harbor 前导入自制Ca 证书位置 mkdir -p /etc/docker/certs.d/registry.lotbrick.com #registry.lotbrick.com 建立域名目录

mkdir -p /etc/docker/certs.d/registry.lotbrick.com
scp ./server.crt  /etc/docker/certs.d/registry.lotbrick.com/ca.crt
systemctl daemon-reload
systemctl restart docker
docker login registry.lotbrick.com

• 安装Jenkins

• yum install -y python-pippip install docker-composecd $HOME && mkdir jenkins && cd jenkinswget https://raw.githubusercontent.com/JyBigBoss/docker-compose/master/jenkins/Dockerfilewget https://raw.githubusercontent.com/JyBigBoss/docker-compose/master/jenkins/docker-compose.yamldocker-compose up -d复制代码

  Jenkins须要安装的插件

• Gitlab Hook、Build Authorization Token Root、Publish Over SSH、Gitlab AuthenticationGitlab、Git Parameter、Git Tag Message、Pipeline、docker-build-step、Docker Pipeline复制代码

  建立git仓库

  • 在web页面建立一个test仓库，并在在仓库中新建一个index.html文件

• cd $HOMEgit clone git@192.168.0.10:yfg/test.gitcd test/cat << EOF > index.html<h1>Test 123</h1>EOFgit add .git commit -m 'add index.html'git push#建立两个taggit tag v1 -m 'version:1'git push --tagsgit tag v2 -m 'version:2'git push --tags复制代码

  　　

  
  
  

  在Harbor上建立一个test仓库

  

  配置Jenkins

  • 打开Jenkins的设置页面，配置Publish over SSH插件

    

  • 建立一个流水线(pipeline)项目

      sh '''cat << EOF > docker-compose.yaml version: "2.4" services: http: image: registry.lotbrick.com/test/http:${check_to_tag} container_name: python-http_server ports: - "80:8000" restart: always EOF'''

      sh 'cat docker-compose.yaml'
  }

  stage('Build Image And Push to registry') {
    //withRegistry('仓库地址','jenkins凭据ID')
    docker.withRegistry('https://registry.lotbrick.com', '9ffa7ef5-38c6-49da-8936-ec596359be56'){
        //build当前目录(workspace)下的Dockerfile
        def BuildImage = docker.build("registry.lotbrick.com/test/http:${check_to_tag}")
        //Push刚才Build出来的镜像
        BuildImage.push()
      }
}
stage('Depoly'){
    //调用Publish Over SSH插件，上传docker-compose.yaml文件而且执行deploy脚本
      sshPublisher(publishers: [sshPublisherDesc(configName: 'jenkins_pipeline_test_deploy', transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: '/bin/bash /root/deploy/deploy.sh', execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: '[, ]+', remoteDirectory: '/root/deploy', remoteDirectorySDF: false, removePrefix: '', sourceFiles: 'docker-compose.yaml')], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])

• 生成流水线脚本的方法
  
  
  
  
  
  

• Jenkins凭据ID获取方法
  
  
  
  
  

• 发布脚本：depoly.sh：放到要部署代码的主机的/root/deploy目录下
