Moving all Docker containers to a new web server: rsync, TCP forwarders and DNS basics.

In this video I explain DNS registration basics and step by step how I copied my Docker containers of my websites from one server to another on the fly and activated them there. During the server move, I used a TCP forwarder to redirect requests from the old server to the new one to bridge the time until the DNS changes are known on the Internet.
