Change variable in Ansible template based on group

Question

I\'ve got an Ansible inventory file a bit like this:

[es-masters]
host1.my-network.com

[es-slaves]
host2.my-network.com
host3.my-network.com

[es:children]
es-m         


        

Answer 1

{% if ansible_fqdn in groups['es-masters'] %}
    {% set node_master=true %}
{% else %}
    {% set node_master=false %}
{% endif %}

maybe like this? change the var which named node_master, rather than use a txt
