My Do-Until loop errors out if the until condition checks against a value
that happens to contain a string like "{{ var }}". I stepped through the
Ansible code and it attempts to evaluate "var" then throws an undefined
variable exception. I have no control over what echo_result.stdout
contains. How can I ask jinja2 to skip nested variable substitution and
leave "{{ var }}" as is while evaluating the until condition?
I have simplified the scenario down to the following playbook below. Thanks
in advance.
