docker的image两个id相同名字不同，如何删除其中之一

问题如下：

[root@echohye ~]# docker images
REPOSITORY                                       TAG        IMAGE ID       CREATED          SIZE
127.0.0.1:5000/echohye                           1.1        409b137b25d9   50 minutes ago   381MB
192.168.1.6:5000/echohye                         1.1        409b137b25d9   50 minutes ago   381MB
mycentos                                         1.1        409b137b25d9   50 minutes ago   381MB
localhost:5000/echohye                           1.1        409b137b25d9   50 minutes ago   381MB

删除的时候，只需要加上镜像名:版本号就行了

[root@echohye ~]# docker rmi 127.0.0.1:5000/echohye:1.1
Untagged: 127.0.0.1:5000/echohye:1.1

[root@echohye ~]# docker rmi localhost:5000/echohye:1.1
Untagged: localhost:5000/echohye:1.1

[root@echohye ~]# docker images
REPOSITORY                                       TAG        IMAGE ID       CREATED          SIZE
192.168.1.6:5000/echohye                         1.1        409b137b25d9   54 minutes ago   381MB
mycentos                                         1.1        409b137b25d9   54 minutes ago   381MB
