I'd also be super interested in some way to do this. To me this is a very
sane use case, and the Ansible appears to allow the use of until: along
with with_items:, but appears to just ignore the until statement. If this
is not supported ideally there would be some sort of syntax issue.
Would the Ansible team be willing to take a pull request to allow until
evaluations in the context of a with_items loop?
For more clarity here is an example play. Lets say we want to send a
update to a single web server out of a set, and you want to stop after the
first successful call. Maybe the calls are not idempotent, maybe you don't
want to add extra load...
here is a test play with until and with_items, and until apparently not
being evaluated.
- hosts: localhost
gather_facts: no
tasks:
- name: test
# action: debug msg="cluster host {{ item }}"
# action: uri timeout=2 url={{ item }}
action: shell curl --max-time 1 {{ item }} >/dev/null
with_items: "{{input_hosts|shuffle}}"
register: put_status
until: put_status.rc == 0
here is the output executing with an input array of URLs, you can see the
first URL works yet it keeps going
ansible-playbook -vv -i ../hosts --sudo test2.yml
--extra-vars='{"input_hosts": ["https://www.google.com";,
"https://www.snargoblarg.com"]}'
