I have done similar things. With enough "experimentation", you can get it
right.
Here's an example from a recent project:
---
all:
vars:
randomkey: "1" # set this first to override
{% for k in inventory_data.key1.key2["key3-with-dashes"] -%}
{% set v = inventory_data.key1.key2["key3-with-dashes"][k] %}
{{ k | indent( width=1 )}}: {% if v is string %}{{ v | to_nice_json }}{%
else %}{{ v | to_nice_json(indent=2) | indent( width=10, first=true) }}{%
endif %}
{% endfor %}
Notice three things:
- the initial spaces in front
- the to_nice_json(indent=2)
- the EXTRA indent(width=10, first=true) afterwards
My workaround here is that nested values end up being json instead of pure
yaml (yaml is a superset of json).
This doesn't produce exactly what I would do with hand crafted yaml, but it
does produce valid yaml.
NB: the inventory_data var is passed in to the template like this:
- name: Create inventory file and populate
template:
src: localhost_inventory.yml.j2
dest: "{{ ansible_dir }}/inventory/localhost.yml"
mode: '0644'
owner: root
vars:
inventory_data: "{{
lookup('file','./ansible-inventory/settings/static/group1/hosts.yml') |
from_yaml }}"
