Proxmox network interface configuration: template error while templating string: Encountered unknown tag 'item'

[Samuel Vandamme]

Hi everyone

I'm trying to setup multiple proxmox network interfaces for my containers with Ansible. 

Here is the code that I'm using. You can see in the netif property that I sometimes want to add a second interface to the container.

- name: Create instances

  proxmox: 

    vmid={{ item.id }} 

    node='simpsons' 

    api_user='{{ proxmox.api.username }}' 

    api_password='{{ proxmox.api.password }}' 

    api_host='localhost' 

    password='{{ item.hostname | b64encode | to_uuid }}' 

    hostname='{{ item.hostname }}' 

    onboot=yes

    memory={{ item.memory }}

    ostemplate='local:vztmpl/debian-8.0-standard_8.4-1_amd64.tar.gz' 

    netif='

      {"net0":"name=eth0,gw=10.100.0.1,ip=10.100.0.{{ item.id }}/24,bridge=vmbr0"}

      {% item.public_ip is defined %}

      ,

      {"net1":"name=eth1,gw=100.100.100.1,ip={{ item.public_ip }}/24,bridge=vmbr0,mac={{ item.public_mac }}"}

      {% endif %}'

  with_items: "{{ containers }}"

When I run my playbook with this task I get the following error: fatal: [xxx]: FAILED! => {"failed": true, "msg": "template error while templating string: Encountered unknown tag 'item'.. String:  {\"net0\":\"name=eth0,gw=10.100.0.1,ip=10.100.0.{{ item.id }}/24,bridge=vmbr0\"} {% item.public_ip is defined %} , {\"net1\":\"name=eth1,gw=100.100.100.1,ip={{ item.public_ip }}/24,bridge=vmbr0,mac={{ item.public_mac }}\"} {% endif %}"}

It feels like I'm taking the wrong approach to this. Can someone point me into the right direction to solve this or provide an alternative method?

ansible 2.1.2.0

Thanks a lot for your time
