This is pools.sls:

{% for pool in salt['pillar.get']('phpfpm:pools').items() %}

{{ pool.confdir }}/{{pool.domain}}.conf:
  file.managed:
    - source: salt://phpfpm/templates/pool.conf.jinja
    - template: jinja
    - pool_name: {{ pool.domain }} #Stanza name
    - pool_user: {{ pool.user }} #Process user
    - pool_group: {{ pool.group }} #Process group
    - require:
      - file: {{ pool.confdir }}
      - user: {{ pool.user }}
      - user: {{ pool.group }}
{% endfor %}

This is phpfpm.sls in the pillar dir:

phpfpm:
  ## Required for Zend Server:
  lookup:
    dirs:
      config: /usr/local/zend/etc/fpm.d
      socket: /usr/local/zend/tmp
    user: www-data
    group: www-data
    listen.group: www-data
    listen.owner: www-data
    pool_name: myhost

  config:
    # Do not remove default configs (required for Zend Server)
    cleanup: False

  pools:
    myhost:
      domain: myhost
      user: www-data
      confdir: /usr/local/zend/etc/fpm.d
      group: www-data


And here is what pillar.item phpfpm returns:
