How to completely and completely transfer it to another host?
PS I find information everywhere on how to transfer an image. But I can’t understand if I transfer the image, then after all, all the changes that were made to the container will not be transferred.

Answer 1

More or less like this. I'm writing from memory, no need to copy-paste it, but you need to read the man page for each of the commands.
docker commit validator magnetikonline/html5validator
docker save magnetikonline/html5validator > /tmp/validator.tar
scp /tmp/validator.tar [email protected]:/tmp/validator.tar
---
docker load < /tmp/validator.tar
docker run validator magnetikonline/html5validator

Answer 2

I can’t understand if I transfer the image, then after all, all the changes that were made to the container will not be transferred.

All changes occur with the image (a layer of changes or several layers is added) and not with the "container". In general, it would be nice to still explain what you named it there. dockerfile?
