Use variables in standard loops

I am trying to user variables in the below example described here.


- name: add several users 
  user: name={{ item.name }}
  state=present groups={{ item.groups }}
  with_items:
    - { name: 'testuser1', groups: 'wheel' }
    - { name: 'testuser2', groups: 'root' }

This works fine, but when I try to infuse variables, it does not works as intended. I am sure, I am doing something wrong.

I’ve defined two lists in my playbook

`
vars:

  • old:
  • ens155
  • ens160
  • new:
  • eth0
  • eth1
    `

I am trying to make below code work like ens155 is eth0 and ens160 is eth1, but this code shows this message - [ens155, ens160] is [eth0, eth1]

`

  • shell: echo {{ item.old }} is {{ item.new }}
    with_items:
  • { old: ‘{{ old }}’, new: ‘{{ new }}’ }
    `

How can I make this work ? If required, I am happy to change the way my variables are defined.

Regards.

The injected old and new are injected as an array. Try it like this:

  • shell: echo {{ item.old }} is {{ item.new }}
    with_items:
  • { old: ‘{{ old[0] }}’, new: ‘{{ new[0] }}’ }
  • { old: ‘{{ old[1] }}’, new: ‘{{ new[1] }}’ }

Thanks Alwin, the number of elements in the list could vary.

This is what I was looking for.

`

  • shell: echo {{ item.0 }} is {{ item.1 }}
    with_together:
  • “{{ old }}”
  • “{{ new }}”
    `

Regards.
