Getting a message on folders created in a loop

Archives Ansible Project

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:

You want to loop over the results, each item is stored in the results list.

- debug:
       msg: folder created {{item.item}}
     loop: '{{result.results}}'
     when: item is not failed
