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

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 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-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

  Jenkins需要安装的插件

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

  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 $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#创建两个taggit tag v1 -m 'version:1'git push --tagsgit 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

}

• 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

• 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
