一、企业业务代码发布方式
1.1 传统方式
- 以物理机或虚拟机为颗粒度部署
- 部署环境比较复杂，需要有先进的自动化运维手段
- 出现问题后重新部署成本大，一般采用集群方式部署
- 部署后以静态方式展现
1.2 容器化方式
- 以容器为颗粒度部署
- 部署方式简单，启动速度快
- 一次构建可到处运行
- 出现故障后，可随时恢复
- 可同时部署多套环境（测试、预发布、生产环境等）

5.6 项目构建及发布
5.6.1 项目构建及发布步骤
第一步：jenkins获取项目代码
第二步：jenkins对项目代码编译，由maven完成
第三步：jenkins使用docker对编译完成的项目代码进行打包，打包成容器应用镜像
第四步：jenkins把打包的容器应用镜像上传到harbor
第五步：jenkins通过ssh插件完成对web-server进行运行容器应用镜像的操作
5.6.2 创建项目任务
