我有一个简单的MERN堆栈SPA，我想为其构建一个docker映像。我一直在搜索一些教程，但是每个人都在构建一个dockerfile，客户端和服务器文件夹是同级而不是父级和子级，所以我想知道是否可行。我将create-react-app用于前端，后端是Nodejs，

文件结构如下：

-server/
  - client/
    - src/
    - public/
    - index.js
    - package.json
    - package-lock.json
  - Dockerfile
  - index.js
  - package.json
  - package-lock.json

这是我的server / package.json：

  "scripts": {
    "start": "node /app/index.js","server": "nodemon /app/index.js","client": "npm run start --prefix client","dev": "concurrently \"npm run server\" \"npm run client\""
  }

我的client / package.json：

"scripts": {
    "start": "react-scripts start","build": "react-scripts build","test": "react-scripts test","eject": "react-scripts eject"
  },"proxy": "http://localhost:5000"

我的服务器/ Dockerfile：

FROM node:10

# Set image metadata
LABEL version="1.0"
LABEL description="Johnny Node"


# Create app directory
WORKDIR /app

# install dependencies
COPY package*.json ./
RUN npm cache clean --force && npm install

# copy app source to image _after_ npm install so that
# application code changes don’t bust the docker cache of
# npm install step
COPY . .


COPY client/package*.json /app/client/

RUN cd /app/client && npm install && npm run build

# set application PORT and expose docker PORT,80 is what Elastic Beanstalk expects
EXPOSE 5000

CMD npm run dev

我遇到了一些奇怪的错误，例如找不到某些模块或npm ERR！ client@0.1.0 build：react-scripts build，不确定我的Dockerfile做错了什么。谢谢你！
