Ansible: Kick off playbook ONLY if a certain directory contains any files


Hi all,

I am fairly new to ansible but have been googling around for the answer to this and just cannot find anything that matches my request. So I wonder if you can assist please??


Basically I have a very long playbook to build an environment and set permissions etc etc etc and I have been instructed that at the very beginning of the PB I need to set a condition that IF a certain directory already contains files (any files at all) then the PB should exit, else it should continue with the rest of the installation and other bits.

How on earth do I do that sort of thing?? I just cannot see a module that helps me apart from it something that checks that the directory exists which is not what I want.

Thanks for any constructive input.

Found and tested some new modules and it worked....

- name: Check if a dir is empty - Exit if not
find:
paths: /bob/test_dir
patterns: '*.*'
register: foundFiles

- debug:
msg: "Install files found. Exiting playbook"
when: foundFiles.matched > 0

- meta: end_play
when: foundFiles.matched > 0

- name: No files detected - Install code
shell: ls -lrt /bob/test_dir ## this is a dummy cmd to show things move on
