Hello guys.
I'm here to bring an issue with Ansible dry-run (--check) mode. I have been
facing a curious situation where package installation made using Playbooks
and run in a dry-run mode is not working as expected. Using register+debug
module it's possible to see that the package has been successfully
installed, but when I try to use that installed package in later task,
Ansible fails.
*My Playbook:*
---
- hosts: logging
become: yes
tasks:
- name: Setting up EPEL
yum: name=epel-release state=present
register: inst
- debug: var=inst
- name: Checking installation
stat:
path: /etc/yum.repos.d/epel.repo
register: file
- fail:
msg: "File epel.repo doesn't exist!"
when: file.stat.exists == False
*Result:*
[root@c7 projX]# ansible-playbook -i inventory epel.yml --check
PLAY [logging]

}

If I take '--check' for dry-run out of the command it does work, but it's
not the best approach for me once I'm planning to put this "checking task"
in a CI software to "automate the automation".
My question is: is there any specific reason for that case (package
installation) not to work with --check parameter? I've done further tests
using Ubuntu and the Ansible's apt module but the same problem comes up.
Could you guys help me?
thank you.
