You can use all of the Jinja2 features in your templates, but we won’t cover them in detail here. Check out the Jinja2 Template Designer Documentation for more details. You probably won’t need to use those advanced templating features, though. One Jinja2 feature you probably will use with Ansible is filters; we’ll cover those in a later chapter. yml playbook, note that there are two new playbook ele‐ ments we haven’t discussed yet. There’s a handlers section that looks like this: handlers: - name: restart nginx service: name=nginx state=restarted In addition, several of the tasks contain a notify key.

Are you sure you want to continue connecting (yes/no)? You can just type yes. If it succeeded, output will look like this: testserver | success >> { "changed": false, "ping": "pong" } If Ansible did not succeed, add the -vvvv flag to see more details about the error: $ ansible testserver -i hosts -m ping -vvvv We can see that the module succeeded. The "changed": false part of the output tells us that executing the module did not change the state of the server. The "ping": "pong" text is output that is specific to the ping module.
