如图：

[root@localhost nginx]# docker images
 REPOSITORY   TAG      IMAGE ID       CREATED      SIZE
                    89e246af3571       About a minute ago   880 MB
 docker.io/ubuntu     latest              7698f282e524        3 months ago         69.9 MB
 docker.io/centos     latest              9f38484d220f        5 months ago         202 MB
 docker.io/registry   latest              f32a97de94e1        5 months ago         25.8 MB

解决：

docker tag 89e246af3571 rojer:nginxV0.0.1

[root@localhost nginx]# docker tag --help
 Usage:    docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]
 Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE
 Options:
       --help   Print usage
