Sudo_user This is the user that Ansible will try and become using sudo. For example, if we set sudo to yes and user to daniel, setting sudo_user to kate will cause Ansible to use sudo to get from daniel to kate once logged in. If you were doing this in an interactive SSH session, we could use sudo -u kate while you are logged in as daniel. connection This allows us to tell Ansible what transport to use to connect to the remote host. We will mostly use ssh or paramiko for remote hosts. However, we could also use local to avoid a connection overhead when running things on the localhost.
The names are also outputted to the console when the playbook is run, so that the user can tell what is happening. If we don't provide a name, Ansible will just use the action line of the task or the handler. Unlike other configuration management tools, Ansible does not provide a fully featured dependency system. This is a blessing and a curse; with a complete dependency system, we can get to a point where we are never quite sure what changes will be applied to a particular machine. Ansible, however, does guarantee that our changes will be executed in the order they are written.
However, they make good documentation and allow us to refer to each task later on, if required. This will become useful especially when we come to handlers.
