For the examples we will use in this chapter, we can install Jenkins on the management host or a separate machine. My personal preference is to install it on a separate virtual machine. The virtual machine will have a similar network set up as the management host up to this point, with one interface for the internet connection and another interface for VMNet 2 connection to the VIRL management network.

$ cat /etc/apt/sources.list | grep jenkins

# install Java8
$ sudo add-apt-repository...
