Hi all,
Just FYI in case that other folks may find this helpful later.
I took Michael's hint, and changed the error_on_undefined_vars from False
to True, which basically returns an explicit error if there exists a
missing variable, as follow.
myproject_foler/.ansible.cfg
#error_on_undefined_vars = False
error_on_undefined_vars = True
And I found that the original error was caused by one missing variable in
the lineinfile command, {{ elasticsearch_URL }}. Once I add those variables
in my vars file, everything start working :-)
In short, lineinfile does take varaiables and it works perfectly
My only slight complaint is that the error message was not as related to
the root cause as it could be.
Thanks to Michael.
