Basically, there are three main installation scenario: Scenario 1: Ironic installation together with other openstack services including keystone. In this case variable enable_keystone is set to true and keystone service will be installed together with ironic installation. It is possible realise this scenario, no fix needed Scenario 2: Ironic installation with connection to already installed keystone. In this scenario we have to set enable_keystone to “No” to prevent from new keystone service installation during the ironic installation process. But in other hand, we need to have correct sections in ironic.conf to provide all information needed to connect to existing keystone. But all sections for keystone are added to ironic.conf only if enable_keystone var is set to “Yes”. It isn’t possible to realise this scenario. Proposed fix provide support for this scenario, where multiple regions share the same keystone service. Scenario 3: No keystone integration. Ironic don't connect to Keystone. It is possible realise this scenario, no fix needed Proposed solution also keep the default behaviour: if no enable_keystone_integration is manually defined by default it takes value of enable_keystone variable and all behaviour is the same. But if we don't want to install keystone and want to connect to existing one at the same time, it will be possible to set enable_keystone var to “No” (preventing keystone from installation) and at the same time set ironic_enable_keystone_integration to Yes to allow needed section appear in ironic.conf through templating.

Kolla Ansible
The Kolla Ansible is a deliverable project separated from Kolla project.
Kolla Ansible deploys OpenStack services and infrastructure components in Docker containers.
Kolla's mission statement is:
To provide production-ready containers and deployment tools for operating
OpenStack clouds.Kolla is highly opinionated out of the box, but allows for complete customization. This permits operators with little experience to deploy OpenStack quickly and as experience grows modify the OpenStack configuration to suit the operator's exact requirements.
Getting Started
Learn about Kolla Ansible by reading the documentation online Kolla Ansible.
Get started by reading the Developer Quickstart.
