如何在集群中的不同机器之间共享 docker 个图像？

Question

I've just started to maintain a cluster consisting of several machines. After deploying the kube.netes on each node, I found out that there is a tedious task for me to load docker images on each machines when I need to use some local mirrors. So here comes the problem, is there any elegant way to spread mirrors among each nodes quickly?

At the moment, I just utilize docker save and docker load command to transfer the image files among these machines by scp. I'd like to find out some way that enables me to do once and spread images to all nodes. Try hard to search for the similar problems, but it seems I cannot get an existing solution for that.

The best way to do this is to run a docker registry image inside one of these VMs and upload it to that. The other VMs, assuming they have.network access to this VM which runs the registry can download from it.
