Docker-compose -f docker-compose.yaml up //image创建成功后，就可以使用Docker-compose来批量的启动服务
Docker-compose -f docker-compose.yaml down //如果需要修改image，那么先使用docker-compose来down所有的服务

FROM node:13-alpine
ENV MONGO_DB_USERNAME=admin \
    MONGO_DB_PWD=password
RUN mkdir -p /home/app
COPY ./app /home/app
WORKDIR /home/app
CMD ["node","server.js"]

RUN 和 CMD的区别：CMD仅运行docker的继承线最后一个，被继承的Dockerfile中的CMD不会被运行。RUN无论处于被继承的image中还是最后的image中，都会被执行。

Docker build -t my-app:1.0 .
Docker rmi my-app:1.0 //删除之前docker build的image

Docker Volumes
3 Volume types:
Host volume: Docker run -v /home/mount/data:/var/libe/mysql/data
Anonymous Voulume: Docker run -v /var/lib/mysql/data
Named volumes: docker run -v name:/var/lib/mysql/data

windows環境下，配置docker容器代理：
~/.docker/config.json
