wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

yum install -y docker-ce

安装Gitlab

• 参考这篇文章：

  http://blog.51cto.com/bigboss/2129284

• Docker方式安装：

  https://github.com/JyBigBoss/docker-compose/blob/master/gitlab/docker-compose.yaml

• 安装Harbor

• 参考：

• http://blog.51cto.com/bigboss/2316525         

• 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"
  

  copydocker 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  创建域名目录          

  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-pip
  pip install docker-compose
  
  cd $HOME && mkdir jenkins && cd jenkins
  wget https://raw.githubusercontent.com/JyBigBoss/docker-compose/master/jenkins/Dockerfile
  wget https://raw.githubusercontent.com/JyBigBoss/docker-compose/master/jenkins/docker-compose.yaml
  
  docker-compose up -d
  

  Jenkins需要安装的插件

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

  创建git仓库

  • 在web页面创建一个test仓库，并在在仓库中新建一个index.html文件

  • cd $HOME
    git clone git@192.168.0.10:yfg/test.git
    cd test/
    cat << EOF > index.html
    <h1>Test 123</h1>
    EOF
    git add .
    git commit -m 'add index.html'
    git push
    
    #创建两个tag
    git tag v1 -m 'version:1'
    git push --tags
    git tag v2 -m 'version:2'
    git push --tags
    

    　　

    
    
    

    ---

    在Harbor上创建一个test仓库

    配置Jenkins

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

      

    • 创建一个流水线(pipeline)项目

      
      
      
      
      
      
      
      
      
      
      
      

  　　

  　　

  node {
    stage(' Git clone ') {
        git branch: 'master', credentialsId: 'a4a81561-8bc0-426e-89f9-b4d4aa1925d6', url: 'git@192.168.0.10:yfg/test.git'
        env.check_to_tag="$TAG"
        sh '[ -n "${check_to_tag}" ] &&  git checkout ${check_to_tag} ||  { echo -e "切换至指定的tag的版本，tag：${check_to_tag} 不存在或为空，请检查输入的tag!" && exit 111; }'
    }
    stage("Create Dockerfile"){
        sh '''cat << EOF > Dockerfile
  FROM python:3.7.1-alpine
  RUN mkdir /test
  WORKDIR /test
  COPY ./ /test
  EXPOSE 8000
  CMD ["python","-m","http.server"]
  EOF'''
        sh 'cat Dockerfile'
    }
    stage("Create docker-compose.yaml "){
        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文件并且执行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

  •   #!/bin/bash
      echo '正在更新版本......'
    
      cd /root/deploy
    
      IMAGE_NAME='registry.lotbrick.com/test/http'
      DOCKER_TAG=`awk -F ':' '/.*image/{print $NF}' docker-compose.yaml`
    
      echo -e "
    "
      docker-compose pull && docker-compose up -d
    
      if [  "$?" == 0 ];then
          echo '删除旧的image'
          OLD_IMAGE=`docker images | grep $IMAGE_NAME | awk '{print $2,$3}' | grep -v "${DOCKER_TAG}" |awk '{print $1}'`
          for i in $OLD_IMAGE;do
              docker rmi http:$i
          done
      else
         echo "更新版本失败！！！"
         exit 111
      fi
