Rocky Series Release Notes¶
Masakari has been enabled for mutable config. Below option may be reloaded by sending SIGHUP to the correct process.
‘retry_notification_new_status_interval’ option will apply to process unfinished notifications.
Operators can now purge the soft-deleted records from the database tables. Added below command to purge the records:
masakari-manage db purge --age_in_days <days> --max_rows <rows>
notificationsdb records will be purged on the basis of
statusfields (finished, ignored, failed) as these records will not be automatically soft-deleted by the system.
Masakari now support policy in code, which means if operators doesn’t need to modify any of the default policy rules, they do not need a policy file. Operators can modify/generate a
policy.yaml.samplefile which will override specific policy rules from their defaults.
Masakari is now configured to work with two oslo.policy CLI scripts that have been added:
The first of these can be called like
oslopolicy-list-redundant --namespace masakariand will output a list of policy rules in policy.[json|yaml] that match the project defaults. These rules can be removed from the policy file as they have no effect there.
The second script can be called like
oslopolicy-policy-generator --namespace masakari --output-file policy-merged.yamland will populate the policy-merged.yaml file with the effective policy. This is the merged results of project defaults and config file overrides.
NOTE: Default policy.json file is now removed as Masakari now uses default policies. A policy file is only needed if overriding one of the defaults.
Operator can now customize workflows to process each type of failure notifications (hosts, instance and process) as per their requirements. Added below new config section for customized recovery flow in a new conf file masakari-custom-recovery-methods.conf
Under [taskflow_driver_recovery_flows] is added below five new config options
‘instance_failure_recovery_tasks’ is a dict of tasks which will recover instance failure.
‘process_failure_recovery_tasks’ is a dict of tasks which will recover process failure.
‘host_auto_failure_recovery_tasks’ is a dict of tasks which will recover host failure for auto recovery.
‘host_rh_failure_recovery_tasks’ is a dict of tasks which will recover host failure for rh recovery on failure host.
WSGI application script
masakari-wsgiis now available. It allows running the masakari APIs using a WSGI server of choice (for example nginx and uwsgi, apache2 with mod_proxy_uwsgi or gunicorn). The eventlet-based servers are still available, but the WSGI options will allow greater deployment flexibility.
