Hi Roman,
Happy to help.
Small request -- can you please send just text based mail in the future?
It would make this a lot easier to read. Thanks!
Quick public service announcement, assuming you are using a recent Ansible,
you should simplify your clauses:
when: none_name not in node_query.json.computer |
map(attribute='displayName') | list
The need to do all the {{ dereference }} is not needed in recent Ansible
and can cause problems.
Also, your lookup is should not nest templates, that won't work.
It should look like:
lookup('file', '/tmp/' + node_name + '_newslave.json')
I'm pretty sure you can't urlencode right there inside the lookup statement
either, so I'd recommend this:
set_fact: my_path={{ '/tmp' + node_name + '_newslave.json' | urlencode }}
Save that variable and then it looks much much cleaner!
{{ lookup('file', my_path) }}
I would also define a variable for the URL so your playbooks can be cleaner.
Also, in the future please report what Ansible version you are using when
you have questions, as that can sometimes be relevant.
Thanks and hope this helps, let us know if you have more questions!
