# 基于centos7构建python3运行环境
# 构建命令: 在Dockerfile文件目录下执行 docker build -t python-centos:3.5 .
# 容器启动命令: docker run -itd --name python --restart always --privileged=true -v /root/dockers/python:/root/python -v /root/dockers/python/cron:/var/spool/cron python-centos:3.5 /usr/sbin/init
# 进入容器：docker exec -it python /bin/bash
