This chapter assumes that you have access to a virtualization-capable environment running Ubuntu 18.04 LTS. Some examples are also performed on CentOS 7. In either of these cases, the examples can be run on either a physical machine (or laptop) running one of the aforementioned operating systems, with a process that has virtualization extensions enabled or a virtual machine with nested virtualization enabled.
Ansible 2.8 is also used later in this chapter and it is assumed you have this installed on the Linux host you are using.
All example code discussed in this chapter is available from GitHub at: https://github.com/PacktPublishing/Hands-On-Enterprise-Automation-on-Linux/tree/master/chapter05.
