创建和dockerized使用react-app反应应用程序并获得如上所述的输出＆＃34; docker-compose up＆＃34;命令但http://0.0.0.0:5000/或http://localhost:5000/

   build: .
   image: react-cli
   container_name: react-cli
   volumes:

FROM mhart/alpine-node:6.12.0

RUN npm install -g npm --prefix=/usr/local
RUN ln -s -f /usr/local/bin/npm /usr/bin/npm

CMD [ "/bin/sh" ]





ENV NPM_CONFIG_LOGLEVEL warn

RUN npm install -g serve
CMD serve -s build
EXPOSE 3000

COPY package.json package.json
COPY semantic.json semantic.json

COPY npm-shrinkwrap.json npm-shrinkwrap.json
RUN npm install gulp-header --save-dev
RUN npm install --no-optional

COPY . .

RUN npm run build --production

RUN serve -s build

这是我的Dockerfile

很可能您没有在主机上公开容器端口。我没看到你的撰写文件看起来如何，但你可能需要添加

撰写文件中的容器定义。
