appropriate redirect link for Docker

[mani0525]

I have Docker file:

FROM cloudron/base:0.10.0
ENV PATH /usr/local/node-6.9.5/bin:$PATH
WORKDIR /tmp
COPY package.json /tmp/
RUN npm config set registry http://registry.npmjs.org/ && npm install
WORKDIR /usr/src/app
COPY . /usr/src/app
RUN cp -a /tmp/node_modules /usr/src/app
RUN npm run build
EXPOSE 8000
CMD [ "npm", "run", "start:production" ]

if I run this by:

then going to http://localhost:8000 works fine but if I want go to http://localhost:8000/about I get error:
Cannot GET /about
What should I do to set it up properly? Of course, using such a URL when developing my React app is fine.
Edit:

 "scripts": {
    "clean": "rimraf dist",
    "compile": "node build/scripts/compile",
    "build": "npm run clean && cross-env NODE_ENV=production npm run compile",
    "start": "cross-env NODE_ENV=development node build/scripts/start",
    "start:production": "cross-env NODE_ENV=production node build/scripts/start",
    "test": "cross-env NODE_ENV=test karma start build/karma.config",
    "test:watch": "npm test -- --watch",
    "lint": "eslint .",
    "lint:fix": "npm run lint -- --fix"
  },

It appears that my start:production is poor.
