在docker集装箱失败的angular度2应用程序。 无法执行启动脚本。
我有一个angular度服务，快速服务和mongo数据库服务的撰写文件。 当我运行docker-compose up –build时，出现以下错误：

这是我的DOCKERFILE ：

这是我的package.json ：

==>看起来像是在npm build和npm start之间丢失了node_modules文件夹，但我找不到原因。
尝试只build立到每一步（通过评论所有的指令后），并find什么时候，通过运行一个容器的构build结果（ docker run -it --rm <ID_OF_BUILT_IMAGE> bash
BTW：
- 你的第一个
FROM是无用的 - 最好使用
ENTRYPOINT而不是CMD -
ng serve的host参数中有太多0（0.0.0.0.0不是有效的IP）
