Rocky Series Release Notes

6.0.0

New Features

• 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>

  NOTE: notifications db records will be purged on the basis of update_at and status fields (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.sample file 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 masakari and 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.yaml and 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

  • [taskflow_driver_recovery_flows]

  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.

Upgrade Notes

• WSGI application script masakari-wsgi is 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.
