}确保本地能够正常运行。
$ npm install express mongoose underscoreFROM node
RUN mkdir -p /home/src
COPY . /home/src
RUN cd /home/src; npm install --registry=https://registry.npm.taobao.org
EXPOSE 3000
CMD ["node", "/home/src/app.js"]进入终端
cd /home
mkdir db
mongod --dbpath=‘/home/db‘启动mongodb服务
6.docker build -t nodejsdemo ./
docker run -it -p 3000:3000 --name nodejsdemo --link=mongodb:mongodb modejsdemo
此时控制台可以看到 server start Listen port:3000
浏览器访问 192.168.99.100:3000
