How to quickly migrate from one server with a docker application to another?

Question

Docker

Now I use this method.

#на первом
docker commit <num> krll/<name>
docker push

#на втором
docker pull krll/<name>
docker run [options] krll/<name>

Is there an easier and smarter way?

Answer 1

through docker save and docker export, then you don’t need to commit anything,
but it’s still the same inappropriate way.

Answer 2

Did I understand you correctly that you are violating the whole concept of Docker and 12 factors - namely, do you have non-stateless containers?
And if you do not violate and use the Docker Registry, then continue to use it.
