I don't know if Docker helps with this, I don't use Docker. But some kind of solution has to exist.
How AWS does updates is it first downloads the new code into a separate folder and then switches the link to point to the new folder instead.
But AWS has an unsatisfactory feeling because it downloads the entire code instead of doing a git update. These are all issues that could be fixed, and someone has to do them. I have no idea if Docker helps with any of them, but the opportunity is still there.
