solve method: the path fo source not mount volumes correctly . use kitematice and select the right path
这里的找不到packages.json 和找不到代码路径有关，主要问题在于kitematic 的版本可能无法识别 docker的compose 文件中mount路径，需要手动挂载项目路径到 volumns 下
挂载到目录后遇到 找不到express 的错误， 
此时，kitematic 管理器中可以使用exec 控制台，进入路径后执行 npm install --save
other question： windows 上docker 默认 default ip 192.168.99.100，如何修改ip：
a current workaround, assuming you've got the Toolbox installed:
Close Kitematic
Delete the current default VM: docker-machine rm -f default
Create a new default machine docker-machine create -d virtualbox --virtualbox-hostonly-cidr "![]()
192.168.99.1/24"
Open Kitematic and it should be using this VM.
这个方案是先停掉kitematic,然后用docker-machine删除默认的vm实例，重新创建一个vm，指定ip,然后启动kitematic，刚创建的就可以自动识别了
