[Openstack-operators] [openstack-ansible] configuration file override

Dear all,

Openstack-ansible (OSA) allows us to override parameters in the configuration files as described here: https://docs.openstack.org/project-deploy-guide/openstack-ansible/draft/app-advanced-config-override.html

there is the following statement:

"You can also apply overrides on a per-host basis with the following configuration in the /etc/openstack_deploy/openstack_user_config.yml file:

compute_hosts:
   900089-compute001:
     ip: 192.0.2.10
     host_vars:
       nova_nova_conf_overrides:
         DEFAULT:
           remove_unused_original_minimum_age_seconds: 43200
         libvirt:
           cpu_mode: host-model
           disk_cachemodes: file=directsync,block=none
         database:
           idle_timeout: 300
           max_pool_size: 10

"

In this example the override is part of a compute host definition and there it is in the host_vars section (compute_hosts -> 900089-compute001 -> host_vars -> override). Is it possible to apply such an override for all the compute hosts by not using the hostname? For instance something like:

" compute_hosts:
       nova_nova_conf_overrides:
         DEFAULT:
           remove_unused_original_minimum_age_seconds: 43200
"

would this be correct?


Thank you,
Laszlo
