How to save has been explained clearly. However, it is not clear how to transmit it. Here I will talk more about how to transmit it. Assume that the name of the package is xiaoming/ubuntu. Let’s save it in tmp first.
sudo docker save -o /tmp/ubuntu.tar xiaoming/ubuntu

Suppose you have an image called ubuntu, then you can use the save and load commands to transfer the image:
Execute on local machine
sudo docker save -o ubuntu.tar ubuntu
The ubuntu.tar file is obtained, copy it to the remote machine, and execute
sudo docker load < ubuntu.tar
That’s how it happened...

In addition to the export/import mechanism of docker mentioned by others, you can also build your own private docker registry.

Then we can open a micro download server.
Finally go to other servers
That’s it.
