Goal

You have docker volume on one host and want to move that volume to another host. For example, you want to transfer PostgreSQL container with it's volume to another host.

Solution

Actually, there is no in-a-box solution from Docker, so we need to:

attach our volume to another container
copy and archive all files
copy archive to another host
