Before we did the experiment is on a host, in fact, in the real environment there are multiple hosts, containers on these hosts to start, run, stop and destroy, related containers will communicate with each other over the network, whether they are running on the same host.For this kind of song Multi-host environment, how should we manage it efficiently?The first problem is: Install and configure
