OpenStack Service Configuration in Kolla
----------------------------------------
TODO(all) fill this section out
.. NOTE:: As of now kolla only supports config overrides for ini based configs.
Kolla allows deployer to override configuration of services. Kolla will look
for file in `/etc/kolla/config/<< sevice name >>/<< config file >>`. This can
be done per-project, per-service or per-service-on-specified-host.
For example to override scheduler_max_attempts in nova scheduler, the operator
need to create `/etc/kolla/config/nova/nova-scheduler.conf with content`:
::
[DEFAULT]
scheduler_max_attempts = 100
If the operator wants to configure compute node ram allocation ratio
on host myhost, the operator needs to create file
`/etc/kolla/config/nova/myhost/nova.conf` with content:
::
[DEFAULT]
ram_allocation_ratio = 5.0
The operator can make these changes after services were already deployed by using
following command
.
::
kolla-ansible reconfigure
