We are going to start by looking at various use cases that involve Linux administration. In this section, we are going to identify a task that is usually done manually and try to automate as much of it as possible. An administrator may still be required in situations where there are errors or misconfiguration.
We are going to divide the following use cases into subcategories to better identify their role in general. In each case, we will look at several Ansible tasks. These will either follow a playbook sequence, be executed if certain conditions are met, or be carried out within a loop.
Within this subsection, we are going to show some use cases involving system administration tasks that can be automated using Ansible playbooks. We will first describe the task and the environment in which it will be executed and then we will write a well-formatted and named playbook to illustrate how Ansible can be used.
