Ansible iterate over hosts in inventory group set by variable

Question

I have the next snippet in my role template:

upstream portal {
 {% set nodes = groups[\"my_dev_cluster\"] %}
 {% for node in nodes %}
 ...do something with nodes         


        

Answer 1

You don't need {{...}} because you're already inside a jinja context (in this case, the {% set ... %} block. Just write:

{% set nodes = groups[cluster_name] %}
