I’m running a playbook that should create 2 folders in a loop. If the
folder is not existing, I wish to get a message that folders was created
In my scenario, folder 1 already exists and only folder 2 was created. But
the message was skipped – I’m guessing that the register is being updated
on every loop and the last task is getting the last update of the register.
My goal Is to show a message on every folder that was created.
Thanks
*Playbook:*
- hosts: gw
become: true
become_user: hdfs
vars:
folders:
- /folder1
- /folder2
tasks:
- name: create Main HDFS folders
shell: hadoop fs -mkdir {{ item }}
register: result
ignore_errors: yes
with_items: "{{ folders }}"
- debug:
msg: " {{ result }}"
- debug:
msg: folder created
when: result is not failed
*Output:*
