1.如何镜像重命名：
第一种方法： docker tag localimage-id repo:new_tag
chenyangdeMacBook-Pro:~ chenyang$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
hello-world latest fce289e99eb9 9 weeks ago 1.84 kB
chenyangdeMacBook-Pro:~ chenyang$ docker tag fce289e99 hello-world:v1
chenyangdeMacBook-Pro:~ chenyang$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
hello-world latest fce289e99eb9 9 weeks ago 1.84 kB
hello-world v1 fce289e99eb9 9 weeks ago 1.84 kB
第二种方法：docker tag repo-name/tag repo:new_tag
最后docker push :
[root@110_151 Dockerfile]# docker push 329054/nginx
The push refers to repository [docker.io/329054/nginx]
