Chapter 2. Top New Features

Each composable service template now contains logic to upgrade the service across major releases. This provides a mechanism to accommodate upgrades through the custom role and composable service architecture.

The director now configures Red Hat OpenStack Platform on existing systems running the latest release of Red Hat Enterprise Linux (for the initial release of Red Hat OpenStack Platform 11, this is version 7.3). This means you can provision systems outside the standard director tools but still use the director to configure these systems to run Red Hat OpenStack Platform while using the custom role and composable service architecture.

The director can now deploy OpenStack Bare Metal Provisioning (ironic) as a standalone role on the overcloud. In previous version, the Ironic role required inclusion on a Split Systemd Controller. Now you can deploy the role on its own.

The director now provides the tripleo-ansible-inventory command that generates an inventory of hosts in the environment. Use this for running Ansible automation tasks on groups of hosts.
