OpenStack Host Aggregates

This role can be used to register host aggregates in nova using the os_nova_host_aggregate module.

Requirements

The OpenStack nova API should be accessible from the target host.

Role Variables

os_host_aggregates_venv is a path to a directory in which to create a virtualenv.

os_host_aggregates_auth_type is an authentication type compatible with the auth_type argument of os_* Ansible modules.

os_host_aggregates_auth is a dict containing authentication information compatible with the auth argument of os_* Ansible modules.

os_host_aggregates_cacert is an optional path to a CA certificate bundle.

os_host_aggregates_interface is the endpoint URL type to fetch from the service catalog. Maybe be one of public, admin, or internal.

os_host_aggregates is a list of nova host aggregates to register. Each item should be a dict containing the item 'name', and optionally:

• 'availability_zone' (name of the availability zone to set on the aggregate)
• 'hosts' (list of hostnames to add to the aggregate)
• 'metadata' (dict of key/value pairs to set on the aggregate)
