所有主机的Docker安装方式

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
mkdir /etc/docker/
cat  /etc/docker/daemon.json
{   "registry-mirrors": ["https://registry.docker-cn.com"],
"live-restore": true,
"default-shm-size": "128M",
"max-concurrent-downloads": 10,
"oom-score-adjust": -1000,
"debug": false
}   
EOF
systemctl enable docker
systemctl restart docker
安装Gitlab

• 
  参考这篇文章：
  　　http://blog.运维网.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.运维网.com/bigboss/2316525
  
  

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  index.html
Test 123
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
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
• 
  编写pipeline脚本,下面是这次测试发布用到的脚本
  
  
  
  • Docker Pipeline插件用法：https://jenkins.io/zh/doc/book/pipeline/docker/
    
  • 完整的pipeline脚本
    
  
  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  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  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 $NF}' docker-compose.yaml`
echo -e "\n"
docker-compose pull && docker-compose up -d
if [  "$?" == 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
