flytekit.CronSchedule#

class flytekit.CronSchedule(cron_expression=None, schedule=None, offset=None, kickoff_time_input_arg=None)[source]#

Use this when you have a launch plan that you want to run on a cron expression. This uses standard cron format in case where you are using default native scheduler using the schedule attribute.

CronSchedule(
    schedule="*/1 * * * *",  # Following schedule runs every min
)

See the User Guide for further examples.

Parameters

cron_expression (str) – This should be a cron expression in AWS style.Shouldn’t be used in case of native scheduler.
schedule (str) – This takes a cron alias (see _VALID_CRON_ALIASES) or a croniter parseable schedule. Only one of this or cron_expression can be set, not both. This uses standard cron format and is supported by native scheduler
offset (str) –
kickoff_time_input_arg (str) –
This is a convenient argument to use when your code needs to know what time a run was kicked off. Supply the name of the input argument of your workflow to this argument here. Note that until Flyte has an atomic clock, there could be a few seconds here and there. That is, if your run is supposed to kick off at 3pm UTC every Weds, it may actually be 15:00:02 or something. Example
```
@workflow
def my_wf(kickoff_time: datetime): ...

schedule = CronSchedule(
    schedule="*/1 * * * *"
    kickoff_time_input_arg="kickoff_time")
```
