Docker Run 命令打包H5及其他后台应用
一、简单的run命令介绍

举个栗子:
docker run -it registry.houbank.net/devi/node:8.11.3
运行容器 并不退出,进入容器
二、使用Run命令构建
第一步:构建一个shell脚本 .node的脚本
# .node
node() {
docker run --rm \ -- rm 删除本地的容器文件系统
-v $(pwd):/project \ -- 磁盘外链一个文件,将需要打包的项目链接到Docker容器中(个人理解)
-w /project \ -- 定义工作目录 (如果了解镜像的工作目录则不需要)
registry.houbank.net/devi/node:8.11.3 [OPTIONS ''npm''] \ --镜像仓库的地址 ,添加npm是因为开始没有npm命令
$* -- 参数
}
第二步 通过scurce .node 临时设置环境变量(用于使用脚本中的npm 函数,借此使用Docker中的npm 及相关node版本)
第三步 通过jenkins 运行
scurce ~/.node
npm install
npm run test
第四步 重启nginx即可
三、使用Run命令构建其他项目
构建其他项目也是同样的方式,但是启动时可能有一定差距,需具体分析相关情况
