1、安装Docker for Windows，点击https://store.docker.com/editions/community/docker-ce-desktop-windows进入下载
2、建立centos7镜像库，可到网易蜂巢选择一份Dockerfile复制，网址为
3、将复制的内容放到新建的Dockerfile文件中，这个文件需要自己创建，但注意这个文件不要加上后缀
这里我复制的内容为：
FROM hub.c.163.com/public/centos:7.2.1511 RUN yum clean all RUN yum install -y yum-plugin-ovl || true RUN yum install -y vim tar wget curl rsync bzip2 iptables tcpdump less telnet net-tools lsof sysstat cronie python-setuptools RUN yum clean all RUN easy_install supervisor RUN cp -f /usr/share/zoneinfo/Asia/Shanghai /etc/localtime EXPOSE 22 RUN mkdir -p /etc/supervisor/conf.d/ RUN /usr/bin/echo_supervisord_conf > /etc/supervisord.conf RUN echo [include] >> /etc/supervisord.conf RUN echo \'files = /etc/supervisor/conf.d/*.conf\' >> /etc/supervisord.conf COPY sshd.conf /etc/supervisor/conf.d/sshd.conf CMD ["/usr/bin/supervisord"]
