Merging role defaults with runtime vars












1















Let's say I've got a role org.foo with the following files:



defaults/main.yml:



service_conf:
includes:
- "thing.conf"
main:
host: "foo.example.com"
port: 1234
# plus a whole bunch more


templates/service.conf.j2:



{% for value in service_conf.includes %}
include '{{ value }}'
{% endfor %}

{% for key,value in service_conf.main.iteritems() %}
{{ key }} = '{{ value }}'
{% endfor %}


and at some point in a task I'd like to:




  1. Append an item to service_conf.includes

  2. Add or modify an entry in service_conf.main


How would I do this?



I've tried set_fact like below, but it ends up replacing the default values rather than modifying them.



- name: adjust config
set_fact:
service_conf:
main:
host: 'app.domain.com'
port: '5678'
tls: 'yes'
when: condition = 'happened'
