Clearly in the jinja template though, it's looped to increment nodeid 
nodelist {
{% set nodeid = 0 %}
{% for host in groups['hacluster'] %}
{% set nodeid = nodeid + 1 %}
    node {
        ring0_addr: {{ hostvars[host]['ansible_' + hostvars[host]['api_interface']]['ipv4']['address'] }}
        name: {{ hostvars[host]['ansible_hostname'] }}
        nodeid: {{ nodeid }}
    }
{% endfor %}
