Random parameters but keeping idempotent

Hello!

I want to add back up task of my databases to cron. I don’t want them to start at the same time. And I have too much hosts to initialize each of them using variables. But if I use random filter it becomes unidempotent. Is it any way how to do what I want keeping idempotency?

Thank you.

How about hashing their hostnames, or using something else unique but constant
about them (last octet of their IP, maybe)?

I've used the random filter to conditionally create either host_vars
with the value (if file exists it doesn't regenerate), optionally you
could create a file on the target in /etc/ansible/facts.d/

Another option would be to create something similar to the password
lookup, a db backed random lookup.

Sounds interesting. How have you done this?

example (i prefer template but this makes it a 1 liner):

- copy: content="[defaults]\ntime={{60|random}}"
dest=/etc/facts.d/mycronscript.facts
  when: ansible_local is not defined or 'mycronscript' in
ansible_local or 'time' not in ansible_local.mycronscripts
