job3:
schedule.present:
- function: test.ping
- seconds: 3600
- splay: 10
This will schedule the command: test.ping every 3600 seconds
(every hour) splaying the time between 0 and 10 seconds
job2:
schedule.present:
- function: test.ping
- seconds: 15
- splay:
start: 10
end: 20
This will schedule the command: test.ping every 15 seconds
splaying the time between 10 and 20 seconds
job1:
schedule.present:
- function: state.sls
- job_args:
- httpd
- job_kwargs:
test: True
- when:
- Monday 5:00pm
- Tuesday 3:00pm
- Wednesday 5:00pm
- Thursday 3:00pm
- Friday 5:00pm
This will schedule the command: state.sls httpd test=True at 5pm on Monday,
Wednesday and Friday, and 3pm on Tuesday and Thursday. Requires that
python-dateutil is installed on the minion.
job1:
schedule.present:
- function: state.sls
- job_args:
- httpd
- job_kwargs:
test: True
- cron: '*/5 * * * *'
Scheduled jobs can also be specified using the format used by cron. This will
schedule the command: state.sls httpd test=True to run every 5 minutes. Requires
that python-croniter is installed on the minion.
job1:
schedule.present:
- function: state.sls
- job_args:
- httpd
- job_kwargs:
test: True
- when:
- Monday 5:00pm

- Thursday 3:00pm
- Friday 5:00pm
- returner: xmpp
- return_config: xmpp_state_run
- return_kwargs:
recipient: user@domain.com
This will schedule the command: state.sls httpd test=True at 5pm on Monday,
Wednesday and Friday, and 3pm on Tuesday and Thursday. Using the xmpp returner
to return the results of the scheduled job, with the alternative configuration
options found in the xmpp_state_run section.
job1:
schedule.present:
- function: state.sls
- job_args:
- httpd
- job_kwargs:
test: True
- hours: 1
- skip_during_range:
- start: 2pm
- end: 3pm
- run_after_skip_range: True
This will schedule the command: state.sls httpd test=True at 5pm on Monday,
Wednesday and Friday, and 3pm on Tuesday and Thursday. Requires that
python-dateutil is installed on the minion.

from __future__ import absolute_import, print_function, unicode_literals
def present(name,
**kwargs):
'''
Ensure a job is present in the schedule
name
The unique name that is given to the scheduled job.
seconds
The scheduled job will be executed after the specified
number of seconds have passed.
minutes
The scheduled job will be executed after the specified
number of minutes have passed.
hours
The scheduled job will be executed after the specified
number of hours have passed.
days
The scheduled job will be executed after the specified
number of days have passed.
when
This will schedule the job at the specified time(s).
The when parameter must be a single value or a dictionary
with the date string(s) using the dateutil format.
Requires python-dateutil.
cron
This will schedule the job at the specified time(s)
using the crontab format.
Requires python-croniter.
run_on_start
Whether the job will run when Salt minion start. Value should be
a boolean.
function
The function that should be executed by the scheduled job.
job_args
The arguments that will be used by the scheduled job.
job_kwargs
The keyword arguments that will be used by the scheduled job.
maxrunning
Ensure that there are no more than N copies of a particular job running.
jid_include
Include the job into the job cache.
splay
The amount of time in seconds to splay a scheduled job.
Can be specified as a single value in seconds or as a dictionary
range with 'start' and 'end' values.
range
This will schedule the command within the range specified.
The range parameter must be a dictionary with the date strings
using the dateutil format. Requires python-dateutil.
once
This will schedule a job to run once on the specified date.
once_fmt
The default date format is ISO 8601 but can be overridden by
also specifying the ``once_fmt`` option.
enabled
Whether the job should be enabled or disabled. Value should be a boolean.
return_job
Whether to return information to the Salt master upon job completion.
metadata
Using the metadata parameter special values can be associated with
a scheduled job. These values are not used in the execution of the job,
but can be used to search for specific jobs later if combined with the
return_job parameter. The metadata parameter must be specified as a
dictionary, othewise it will be ignored.
returner
The returner to use to return the results of the scheduled job.
return_config
The alternative configuration to use for returner configuration options.
return_kwargs
Any individual returner configuration items to override. Should be passed
as a dictionary.
persist
Whether the job should persist between minion restarts, defaults to True.
skip_during_range
This will ensure that the scheduled command does not run within the
range specified. The range parameter must be a dictionary with the
date strings using the dateutil format. Requires python-dateutil.
run_after_skip_range
Whether the job should run immediately after the skip_during_range time
period ends.
