cinder.service module¶
Generic Node base class for all workers that run on hosts.
- class Launcher¶
Bases:
object
- class Service(host, binary, topic, manager, report_interval=None, periodic_interval=None, periodic_fuzzy_delay=None, service_name=None, coordination=False, cluster=None, *args, **kwargs)¶

- classmethod create(host=None, binary=None, topic=None, manager=None, report_interval=None, periodic_interval=None, periodic_fuzzy_delay=None, service_name=None, coordination=False, cluster=None, **kwargs)¶
Instantiates class and passes back application object.
- Parameters
host – defaults to CONF.host
binary – defaults to basename of executable
topic – defaults to bin_name - ‘cinder-‘ part
manager – defaults to CONF.<topic>_manager
report_interval – defaults to CONF.report_interval
periodic_interval – defaults to CONF.periodic_interval
periodic_fuzzy_delay – defaults to CONF.periodic_fuzzy_delay
