企业业务代码发布逻辑图

工具使用

工具	工具用途
git	用于提交业务代码或克隆业务代码仓库
gitlab	用于存储业务代码
jenkins	用于利用插件完成业务代码编译、构建、推送至Harbor容器镜像仓库及项目部署
tomcat	用于运行JAVA业务代码
maven	用于编译业务代码
harbor	用于存储业务代码构建的容器镜像存储
docker	用于构建容器镜像，部署项目

流程图

企业业务代码发布系统环境部署

主机规划

主机名	主机IP	主机功能	软件
dev	192.168.10.20	开发者 项目代码 solo	git
gitlab-server	192.168.10.21	代码仓库	gitlab-ce
jenkins-server	192.168.10.22	编译代码、打包镜像、项目发布	jenkins、docker、git
harbor-server	192.168.10.23	存储容器镜像	harbor、docker
web-server	192.168.10.24	运行容器，项目上线	harbor、docker
