Preparing a Docker host
It is assumed that we are already familiar on how to set up a Docker host. For most of the chapters of this book, we will run against the following environment unless mentioned explicitly:
- Operating System: CentOS 7.5
- Docker version: 18.09.0
The following commands display the operating system and Docker Engine version running inside our Docker host:
$ ssh dockerhost
dockerhost$ lsb_release -a
LSB Version: :core-4.1-amd64:core-4.1-noarch
Distributor ID: CentOS
