3. 定义数据卷容器: 只是为了共享数据docker run -itd -v /data/  --name centeos_testv centos  bash/data/ 就是虚拟机内的目录,和宿主机没有任何关系--name centeos_testv 容器名字docker:/root# docker imagesREPOSITORY                                    TAG                 IMAGE ID            CREATED             VIRTUAL SIZE192.168.32.150:5000/zjzc_centos6.5_template   latest              f01c69d919d1        2 days ago          975.4 MBdocker:/root# docker run -itd -v /data/  --name centeos_test02 192.168.32.150:5000/zjzc_centos6.5_template   bash623d933a9f3b42415f9d56bbc214860868895926b3a62092225076321aee1d97docker:/root# docker run -itd -v /data/  --name centeos_test02 192.168.32.150:5000/zjzc_centos6.5_template   bashError response from daemon: Conflict.
