Hi,

I want to do loop in the dict variable appliance and in variable have var count. This count I should like loop count.

appliances:
fw01:
count: 2
vmname: name
image: redhat
os_type: Linux
data_disks:

  • lun: 0
    disk_size_gb: 128
    managed_disk_type: Standard_LRS

I create this task debug for tests:

  • name: virtual_machine
    debug:
    msg: “{{ item.key }} - {{ item.value.count }}”
    with_dict:
  • “{{ virtual_machine }}”
    with_sequence: start=0 end=“{{ item.value.count }}”

but return this error:

ERROR! duplicate loop in task: sequence

How can create this loop?

Matt Martz gave you the answer yesterday when you asked exactly the same question.

Hi Rafael,

I want to do loop in the dict variable appliance and in variable have var
count. This count I should like loop count.

appliances:
  fw01:
    count: 2
    vmname: name
    image: redhat
    os_type: Linux
    data_disks:
      - lun: 0
        disk_size_gb: 128
        managed_disk_type: Standard_LRS

- name: virtual_machine
  debug:
    msg: "{{ item.key }} - {{ item.value.count }}"
  with_dict:
    - "{{ virtual_machine }}"
  with_sequence: start=0 end="{{ item.value.count }}"

but return this error:
ERROR! duplicate loop in task: sequence

How can create this loop?

It's possible to *include_tasks* and create nested loops. For this purpose
it's necessary to "Define inner and outer variable names with loop_var"
https://docs.ansible.com/ansible/latest/user_guide/playbooks_loops.html#defining-inner-and-outer-variable-names-with-loop-var

For example the playbook

    $ cat playbook.yml
    - hosts: master
      tasks:
        - include_tasks: create-vm.yml
          loop: "{{ appliances|dict2items }}"

with this included file

    $ cat create-vm.yml
    - name: virtual_machine
      debug:
        msg: "{{ item.key }} - {{ inner_item }}"
      with_sequence: start=0 end="{{ item.value.count - 1 }}"
      loop_control:
        loop_var: inner_item

should give

    ok: [master] => (item=0) => {
        "msg": "fw01 - 0"
    }
    ok: [master] => (item=1) => {
        "msg": "fw01 - 1"
    }

Cheers,
