Jinja templating doesn’t work in playbooks in that way. Lots of variable
constructs are actually parsed with jinja2, so you can do stuff like
- set_fact:
myvar: "{% if something %}this{% else %}that{% endif %}"
As Giovanni mentioned, there are numerous looping constructs for things
like task repetition. Playbooks are declarative, so it wouldn’t really be
right to build them from a template.
