Pike Series Release Notes¶
16.0.0¶
New Features¶
Capping the default value for the variable
ironic_wsgi_processes
to 16 when the user doesn’t configure this variable. Default value is one fourth the number of vCPUs available on the machine with a capping value of 16.
New variables have been added to allow a deployer to customize a ironic systemd unit file to their liking.
The task dropping the ironic systemd unit files now uses the
config_template
action plugin allowing deployers access to customize the unit files as they see fit without having to load extra options into the defaults and polute the generic systemd unit file with jinja2 variables and conditionals.
For the
os_ironic
role, the systemd unitTimeoutSec
value which controls the time between sending a SIGTERM signal and a SIGKILL signal when stopping or restarting the service has been reduced from 300 seconds to 120 seconds. This provides 2 minutes for long-lived sessions to drain while preventing new ones from starting before a restart or a stop. TheRestartSec
value which controls the time between the service stop and start when restarting has been reduced from 150 seconds to 2 seconds to make the restart happen faster. These values can be adjusted by using theironic_*_init_config_overrides
variables which use theconfig_template
task to change template defaults.
