Repeat N times for each element of the list in Ansible

It’s the usual ‘suck at iterations’ problem in Ansible.

My problem:

        mytasks:
          - name: foo
            repeat: 10
          - name: bar
            repeat: 99

I need to create foo-0, foo-1, …, foo-9, bar-0, bar-1,…, bar-99 in a single loop in Ansible.

The ugly solution with subelements will be like this:

    - name: Generating tasks
      debug:
        msg: "{{ item.0.name }}-{{ item.1 }}"
      loop: "{{ mytasks | subelements('ids') }}"

To make it works (I changed ‘repeat’ to ids) we need to alter mytasks:

mytasks:
 - name: foo
   ids: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Don’t ask me to write bar with ids from 0 to 99. I hate it.

I tried to invent crazy wheels with range filter for subelements for ‘repeat’, and I couldn’t.

Alexander, my colleague, found an elegant solution which really I love:

mytasks:
    - name: foo
      ids: "{{ range(0, 10) }}"
    - name: bar
      ids: "{{ range(0, 99) }}"

And it works with a task shown above. And you don’t need to enumerate all integers. Beautiful!
