Building a patch from docker registry?

Question

Docker

Good afternoon! There is a local docker registry and a docker registry, which is located on another server without internet access. Task: compile a patch from the local docker registry, write it to an external hard drive, then connect this hard drive to a server without the Internet, update the docker registry on this server.
Recommend how best to do this or poke your nose where you can see an example?

Docker: save/load container using tgz file (tar.gz)
for not running docker, use save:
for running or paused docker, use export:
load
gunzip -c mycontainer.tgz | docker load
