Several months back I was working quite a bit with MAAS and
needed a way to fully automate not only the MAAS deployment but also the
management of VMs. In this case they were VMs running on KVM .
So as I am backfilling with posts and catching up on some things that I had
intended on sharing this would be one of them.
First thing is to grab the ansible-maas
Ansible role if you would like to use that. This role is actually a very basic
single host deployment but can easily be adapted to separate out functionality
if needed.
Once you have your MAAS deployment completed you are then ready for managing MAAS
with what else other than, Ansible of course. Below you will find the templates
and playbook used for managing MAAS.
To generate MAAS Ansible inventory you can use the following Jinja2 template:
[maas_non_provisioned]
{% for host in (maas_machines['stdout']|from_json) %}
{% if groups['maas_deployed_machines'] is defined %}
{% if host['fqdn'] not in groups['maas_deployed_machines'] %}
{{ host['fqdn'] }}
{% elif host['hostname'] not in groups['maas_deployed_machines'] %}
{{ host['hostname'] }}
{% endif %}
{% elif groups['maas_deployed_machines'] is not defined %}
{{ host['fqdn'] }}
{{ host['hostname'] }}
{% endif %}
{% endfor %}
{% if kvm_vms_list is defined %}
{% if groups['maas_deployed_machines'] is defined %}
{% for kvm_vm in kvm_vms_list %}
{% if kvm_vm not in groups['maas_deployed_machines'] %}
{{ kvm_vm }}
{% endif %}
{% endfor %}
{% elif groups['maas_deployed_machines'] is not defined %}
{% for kvm_vm in kvm_vms_list %}
{{ kvm_vm }}
{% endfor %}
{% endif %}
{% endif %}
To generate MAAS related variables based dynamic discovery you can use the
following Jinja2 template:
---
# Defined vars from first maas play to continue onto additional plays.
# these will eventually be put into group_vars
inventory_directory: '{{ inventory_directory }}'
maas_login_profile: '{{ maas_login_profile }}'
maas_login_url: '{{ maas_login_url }}'
maas_login_user: '{{ maas_login_user }}'

# Defined machines marked as broken
{% if groups['maas_broken_machines'] is defined %}
maas_broken_machines:

{% endfor %}

maas_broken_machines: []
{% endif %}

{% endif %}

{% endif %}

{% if groups['maas_power_unknown_machines'] is defined %}
maas_power_unknown_machines:
