bootstrap_expect is wrong when using consul

[blmhemu]

In the below line, we are checking if consul is NOT enabled. But when consul is enabled, the bootstrap_expect is wrongly being set to 3 whatever be the actual count. This is causing nomad to fail in some cases.

I had the same problem as you. You can fix the problem by initializing the variable nomad_servers differently in defaults/main.yml.

nomad_servers: "\
    {% set _nomad_servers = [] %}\
    {% for host in groups[nomad_group_name] %}\
      {% set _nomad_node_role = hostvars[host]['nomad_node_role'] | default('client', true) %}\
      {% if ( _nomad_node_role == 'server' or _nomad_node_role == 'both') %}\
        {% if _nomad_servers.append(host) %}{% endif %}\
      {% endif %}\
    {% endfor %}\
    {{ _nomad_servers }}\ "
