Docker run-d<；私人形象>；致命的。在其他主机上，它'；好吗？

让命令自己说话：

在名为：coreworker的主机上

core@coreworker-1 ~ $ docker images

现在在位于hub docker repo的devhost上运行映像

很快就到了：

core@devhost ~ $ ping hub-docker-repo
PING hub-docker-repo.service.consul (172.17.8.150) 56(84) bytes of data.
64 bytes from coreworker-1.node.dc1.consul (172.17.8.150): icmp_seq=1 ttl=63 time=8.27 ms
64 bytes from coreworker-1.node.dc1.consul (172.17.8.150): icmp_seq=2 ttl=63 time=5.19 ms

现在试试看

core@devhost ~ $ docker run -d hub-docker-repo:5000/485d5874-c786-4b90-93ac-8db5342a6059:1
Unable to find image 'hub-docker-repo:5000/485d5874-c786-4b90-93ac-8db5342a6059:1' locally

FATA[0000] Error: image 485d5874-c786-4b90-93ac-8db5342a6059:1 not found

现在在实际托管注册表的coreworker上试用它（作为docker映像）

为什么我不能运行远程映像？或者更好的是，甚至可以发现它？

事实证明，该图像从未被推送过，因此其他主机无法看到
