In this chapter, we have covered the fundamentals of Ansible and the way to use it together with Docker. As an exercise, we propose the following tasks:

1. Create the server infrastructure and use Ansible to manage it.
   • Connect a physical machine or run a VirtualBox machine to emulate the remote server
   • Configure SSH access to the remote machine (SSH keys)

2. Create a Python-based "hello world" web service and deploy it in a remote machine using Ansible playbook.
   • The service can look exactly the same as described in the exercises for the chapter
   • Create a playbook, which deploys the service into the remote machine
   • Run the ansible-playbook command and check whether...
