title: can't run react app with docker container
body: <p>I have a react-app, which simple showing hello-world message but I like to run the app throug docker-container but having this problem. After this message, process stopped without running app..   </p>
  
  <pre><code>ℹ ｢wds｣: Project is running at http://172.17.0.2/
  ℹ ｢wds｣: webpack output is served from
  ℹ ｢wds｣: Content not from webpack is served from /app/public
  ℹ ｢wds｣: 404s will fallback to /
   Starting the development server...
  </code></pre>
  
  <p>Can't understand what I should do because I have very small app with basic code in Dockerfile</p>
  
  <pre><code>FROM node:alpine
  RUN mkdir /app
  COPY . /app
  WORKDIR /app
  COPY package.json ./
  RUN npm install
  CMD ["npm", "start"]
  </code></pre>
  
  <p>Do I need to install webpack-dev-server, I tried but got version error like 'manually added server' has lower version than already server. so I re-install the webpack-dev-server.</p>
  
  <p>I have created app with 'create-react-app', so I think every dependency is managed automatically..
  Is anyone have idea, how can I solve the problem.. thanks in advance (BTW..)</p>
  
  <p>Command which I use to build: <code>docker build . -t lucki</code></p>
  
  <p>Command to run image:  <code>docker run -p 3000:3000 lucki</code></p>
