解决删除镜像时image is referenced in multiple repositories

rt@123:~# docker images
REPOSITORY                                  TAG                 IMAGE ID            CREATED             SIZE
192.168.0.1/jii/jenkins                    1.0.1              3391ef1391f6        18 hours ago        206 MB
192.168.0.1/you/tom                        1.0.8              f8ab12e03d53        22 hours ago        276 MB
192.168.0.1/you/tom                        1.0.9              f8ab12e03d53        22 hours ago        276 MB

rt@123:~# docker rmi f8ab12e03d53
Error response from daemon: conflict: unable to delete f8ab12e03d53 (must be forced) - image is referenced in multiple repositories

3、删除时可以用repository和tag的方式来删除

rt@123:~# docker rmi 192.168.0.1/you/tom:1.0.8
Untagged:192.168.0.1/you/tom:1.0.8

rt@123:~# docker images
REPOSITORY                                  TAG                 IMAGE ID            CREATED             SIZE
192.168.0.1/jii/jenkins                    1.0.1              3391ef1391f6        18 hours ago        206 MB
192.168.0.1/you/tom                        1.0.9              f8ab12e03d53        22 hours ago        276 MB
