Saltstack get grains of a minion in orchestration

I'm using salt-cloud to deploy VMs and I'm trying to get them registred in my DNS with the Saltstack Reactor system.

I have a reactor.conf with this trigger:

reactor:
  - 'salt/cloud/*/created':           # Add a VM
    - /srv/reactor/initialize_vm.sls

initilize_vm.sls :

invoke_orchestrate_add_to_dns:
  runner.state.orchestrate:
    - mods: orch.add_to_dns
    - pillar:
        event_name: {{ name }}
        event_profile: {{ profile }}

orch/add_to_dns.sls:

{% set name = pillar['event_name'] %}
{% set profile = pillar['event_profile'] %}

vm-add-dns-{{ name }}:
  sqlite3.row_present:
    - db: /var/lib/powerdns/pdns.sqlite3
    - table: records
    - where_sql: "name='{{ name }}' and type='A'"
    - data:
        domain_id: 1
        name: {{ name }}
        type: A
        content: {{ ??? }}
        ttl: 300
        prio: 0
        disabled: 0

I just need to know the IP address of the new minion. But as the orchestration run on the master, I can't just do a content: {{ grains['fqdn_ip4'] }}.

Any ideas to get minions informations ?

If you don't wish to add configuration you can also do the following:

{% set ip = salt.saltutil.runner('salt.execute', [data['id']], {'fun': 'grains.get', 'kwarg': {'key':'fqdn_ip4'}})[data['id']] %}

Or as mentioned in the comments:

{% set ip = salt['saltutil.runner']('cache.grains', tgt=data['id'])[data['id']]['fqdn_ip4'][0] %}

Figured I'd add this here as a reference for others.
