Hi, I just got a warning in my playbook after updating Ansible to 2.5. Just wanted to let you know. :-)

[DEPRECATION WARNING]: Using tests as filters is deprecated. Instead of using `result|search` instead use `result is search`. This feature will be removed in version 2.9.

db_create_result.stdout|search('already exists. Skipped') }}

ok: [192.168.33.10]

Hey sokphea chea!

Ah, awesome! So, in Ansible 2.3, they deprecated using the jinja syntax in when and changed_when. But actually, that's ok! I didn't realize it, but those {{ are totally unnecessary. So, remove them :). Everything will still work the same and the warnings will go away. We're going to update our code to show that!

Thanks for the ping on this!

Cheers!
