I'm currently having a var in my ./vars/default.yml, which is used at
several points in my playbook for branching installation operations.
boolean_var: true
Depending on this I'm performing (or not) install steps
....
when: not boolean_var
So far so good. I'm also using this var in some j2 templates like so:
{% if boolean_var %}
...
{% endif %}
My problem is, that I mostly forget to set this variable to a proper state,
which reflects the real status on the host system, so I have to abort an
update.
I would rather like to derive it from a pre_task, checking the existence of
a particular file on the host before starting all operations.
Is there a way to define a variable with the same scope (playbook and
templates) at runtime?
