hello,
I find very interesting this way of organizing variables for .ini files.
I wanted to use it myself, so I worked on a plugin that allows to generate
all the keys of an .ini file in one pass with the inifile module.
It works fine and I use to manage my OpenStack configuration files.
I am not a specialist in development, but I think this plugin can be useful
for everyone, so if someone wants to take over to maintain and integrate it
into ansible, he is welcome.
The plugin transforms the hierarchy data in a list (section, key, value)
for use directly with the inifile module with_inidata as below:
vars file :
...
glanceapi_conf:
DEFAULT:
verbose: "{{ image_log_verbose }}"
rabbit_host: "{{ amqp_host }}"
rabbit_port: "{{ amqp_port }}"
rabbit_userid: "{{ amqp_userid }}"
rabbit_password: "{{ amqp_password }}"
rabbit_ha_queues: "{{ amqp_ha_queues }}"
database:
connection: "mysql://{{ image_db_user }}:{{ image_db_password }}@{{
db_host }}/{{ image_db }}"
keystone_authtoken:
auth_uri: "http://{{ identity_admin_host }}:{{ identity_api_port
}}/v2.0"
identity_uri: "http://{{ identity_admin_host }}:{{ identity_admin_port
}}"
admin_tenant_name: "{{ image_ks_tenant }}"
admin_user: "{{ image_ks_user }}"
admin_password: "{{ image_ks_password }}"
paste_deploy:
flavor: keystone
glance_store:
default_store: file
filesystem_store_datadir: /var/lib/glance/images/
...
plugin code :

self.basedir = basedir

if not isinstance(terms[item0], dict):

Task code :
- name: configuration.modify_glance-api_conf_file / modify glance-api.conf
ini file
ini_file:
section: "{{ item.0 }}"
dest: /etc/glance/glance-api.conf
option: "{{ item.1 }}"
value: "{{ item.2 }}"
backup: yes
with_inidata: glanceapi_conf
To use it, simply copy the plugin code with the name "dataini" in the
directory defined in /etc/ansible.cfg. This should be
/usr/share/ansible_plugins/lookup_plugins
for the Ubuntu distribution and write your tasks as in my example. That's
all.
I hope that this plugin will allow you to simplify your ini files
management.
Best Regards
