Due to a change of lower MySQL module from MySQLdb to pymsql, Ansible calls to mysql_db and mysql_user modules fail.

bifrost-keystone-install
This role installs keystone for a bifrost/stand-alone ironic deployment with all required substrate to allow for keystone configuration, including MySQL, RabbitMQ, dnsmasq, and nginx.
Requirements
This role requires:
- Ansible 2.1
Role Variables
Due to the required configuration steps, the configuration must be fairly explicit. The defaults should work for a user without any issues, however it is highly recommended that the parameters are reviewed and modified prior to deployment.
The main settings are in a nested data structure under the name
keystone. In order to logically separate the settings in order
to provide the greatest flexibility for change, under keystone
exists three subsections. bootstrap, message_queue, and
database.
The keystone.bootstrap settings provide the information to access
keystone as it provides the main administrative credentials.
If keystone is being installed, then these credentials will be used
to bootstrap the new keystone installation.
In addition to the bootstrap parameters, we provide the ability to
define the initial region_name, as well as admin_url,
public_url, and internal_url endpoints URLs for keystone.
If the intent is to utilize a pre-existing keystone service that has
already undergone bootstrapping, set the keystone.bootstrap.enabled
setting to false, in order to prevent bifrost from attempting to
bootstrap a new keystone. The keystone.bootstrap settings are
expected to be available by the bifrost-ironic-install role,
which has the same datastructure available in it's defaults/main.yml
file. These settings are used by the birost-ironic-install role
in order to create users, roles, and endpoints for Ironic's operation.
Under the message_queue and database structures, variables
are used to define the connection URLs to the message queue,
and database.
Below is the full data structure.
keystone: debug: true bootstrap: enabled: true username: admin password: ChangeThisPa55w0rd project_name: admin admin_url: "http://127.0.0.1:35357/v2.0/" public_url: "http://127.0.0.1:5000/v2.0/" internal_url: "http://127.0.0.1:5000/v2.0/" region_name: "RegionOne" message_queue: username: keystone password: ChangeThisPa55w0rd host: 127.0.0.1 port: 5672 database: name: keystone username: keystone password: ChangeThisPa55w0rd host: 127.0.0.1
Notes
None
Dependencies
The ansible module, os_keystone_session, is required by this module.
The env-setup.sh script should collect this file and place it in the proper location prior to executing this role.
Example Playbook
NOTE: The bifrost-keystone-install playbook
should be run before the ironic install playbook
to enable the same variables to be utilized.
- hosts: localhost
connection: local
name: "Install ironic locally"
become: yes
gather_facts: yes
