Schedule jobs using cron expressions

There are different ways to trigger OCP jobs:

Trigger the job by another part of the app, like a form
Use a cron expression to run the job periodically on a given schedule

Use opti-cli command:

opti jobs trigger <appId> <jobName> <trackerId>

Schedule jobs with cron expressions

Use the cron property in the app manifest file (app.yml) to schedule the regular execution of a job. The property uses quartz cron format.

Examples:

Expression	Description
- - ? *	Every second
0 _ ? _	Every minute
0 /2 ? * *	Every even minute
0 /2 ? * *	Every 2 minutes
0 /5 ? * *	Every 5 minutes
0 /10 ? * *	Every 10 minutes
0 /15 ? * *	Every 15 minutes
0 /30 ? * *	Every 30 minutes
0 15,30,45 ? *	Every hour at minutes 15, 30 and 45
0 0 /2 ? *	Every hour
0 0 0/2 ? * *	Every even hour
0 0 /12 ? *	Every twelve hours
0 0 12 * * ?	Every day at noon - 12pm
0 0 12 ? *	SUN Every Sunday at noon

To build your own cron expression, you can use a free formatter.

Example of YAML configuration:

jobs:
  nightly_import:
    entry_point: NightlyImport
    # runs at midnight every night
    cron: 0 0 0 ? * *
    description: Performs a nightly import for data that is not provided or needed in real time
