Question

Looking for help with a problem I\'ve been struggling with for a few hours. I want to iterate over a list, run a command, register the output for each command and then iterate w

Answer 1

OK so I found a post on stackoverflow that helped me better understand what is going on here and how to access the elements in result.results.

The resultant code I ended up with was:

---

- hosts: localhost
  gather_facts: false

  vars:
    numbers:
      - name: "first"
        int: "1"
      - name: "second"
        int: "2"

  tasks:

    - name: Register output
      command: "/bin/echo {{ item.int }}"
      register: echo_out
      with_items: "{{ numbers }}"

    - debug: msg="item.item={{item.item.name}}, item.stdout={{item.stdout}}"
      with_items: "{{ echo_out.results }}"

Which gave me the desired result:

"msg": "item.item=first, item.stdout=1"
"msg": "item.item=second, item.stdout=2"

Answer 2

I am not sure if I understand the question correctly, but maybe this can help:

    - debug: msg="{{ item.stdout }}"
      with_items: echo_out.results

Please note that Ansible will print each item and the msg both - so you need to look carefully for a line that looks like "msg": "2".
