Julia Kreger ff75b0cf4b Make ironic database use more configurable
Basic changes to allow for greater flexibility
in detailed configurations that may scale beyond
a single coductor host, or cases where a remote
database server may need to be utilized.

Also removed a note from the defaults file which
no longer made sense. I think it was an incomplete
thought that I had accidently committed at some point.

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 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 roles:
    • role: bifrost-keystone-install
    • role: bifrost-ironic-install
