Rocky Series Release Notes¶

New Features¶

• New variables have been added to allow a deployer to customize a monasca systemd unit file to their liking.

• The task dropping the monasca 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.

• The service setup in keystone for monasca will now be executed through delegation to the monasca_service_setup_host which, by default, is localhost (the deploy host). Deployers can opt to rather change this to the utility container by implementing the following override in user_variables.yml.

  monasca_service_setup_host: "{{ groups['utility_all'][0] }}"
  

• For the os_monasca role, the systemd unit TimeoutSec 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. The RestartSec 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 the monasca_*_init_config_overrides variables which use the config_template task to change template defaults.

Deprecation Notes¶

• The variable monasca_requires_pip_packages is no longer required and has therefore been removed.
