4.将镜像推送到阿里云 Registry

[root@host1 ~]# docker tag hello-world crpi-xyb4ez7e48w6bh7l.cn-chengdu.personal.cr.aliyuncs.com/docker_sjl/hello-world
[root@host1 ~]# docker images | grep hello-world
crpi-xyb4ez7e48w6bh7l.cn-chengdu.personal.cr.aliyuncs.com/docker_sjl/hello-world   latest    1b44b5a3e06a   4 weeks ago     10.1kB
hello-world                                                                        latest    1b44b5a3e06a   4 weeks ago     10.1kB

        然后执行 docker push 命令推送该镜像

[root@host1 ~]# docker tag 1b44b5a3e06a  crpi-xyb4ez7e48w6bh7l.cn-chengdu.personal.cr.aliyuncs.com/docker_sji/hello-world
