Hello there,
Is it possible to create a variable which is a dict using jinja2 within a
playbook?
For example, I have the following (contrived) playbook, within which I am
trying to create a 'host_info' dict which I can then access from a task:
---
- hosts: 127.0.0.1
connection: local
sudo: no
vars:
app_servers: 5
ipaddress_base: "192.168.0"
rmi_portbase: 10000
host_info: |
{%- for number in range(1,app_servers + 1) -%}
{% set host = 'app' + number|string %}
- hostname: host
- ipaddress: {{ ipaddress_base }}.{{ number }}
- rmi_port: {{ rmi_portbase|int + ( number * 10) }}
{%- endfor %}
tasks:
- debug: var=item
with_items: host_info
- debug: var=item.hostname
with_dict: host_info
However I can't seem to generate a dict as intended.
$ ansible-playbook -i "localhost," test.yml
PLAY [127.0.0.1]

}

PLAY RECAP

to retry, use: --limit @/tmp/test.retry
127.0.0.1 : ok=2 changed=0 unreachable=1 failed=0
Any thoughts / assistance would be appreciated.
cheers,
Anth
