[jenkins] How do I schedule jobs in Jenkins?

I added a new job in Jenkins, which I want to schedule periodically.

From Configure job, I am checking the "Build Periodically" checkbox and in the Schedule text field added the expression:

15 13 * * *

But it does not run at the scheduled time.

Is it the correct procedure to schedule a job?

The job should run at 4:20 AM, but it is not running.

To schedule a cron job every 5 minutes, you need to define the cron settings like this:

*/5 * * * *

Jenkins uses Cron format on scheduling. You can refer this link for more detailhttps://en.wikipedia.org/wiki/Cron. One more thing, Jenkins provide us a very useful preview. Please take a look on the screenshot.

I hope this help. Thanks

Try this.

20 4 * * *

Try using 0 8 * * *. It should work

The steps for schedule jobs in Jenkins:

1. click on "Configure" of the job requirement
2. scroll down to "Build Triggers" - subtitle
3. Click on the checkBox of Build periodically
4. Add time schedule in the Schedule field, for example, @midnight

Note: under the schedule field, can see the last and the next date-time run.

Jenkins also supports predefined aliases to schedule build:

@hourly, @daily, @weekly, @monthly, @midnight

@hourly --> Build every hour at the beginning of the hour --> 0 * * * *

@daily, @midnight --> Build every day at midnight --> 0 0 * * *

@weekly --> Build every week at midnight on Sunday morning --> 0 0 * * 0

@monthly --> Build every month at midnight of the first day of the month --> 0 0 1 * *

Jenkins lets you set up multiple times, separated by line breaks.

If you need it to build daily at 7 am, along with every Sunday at 4 pm, the below works well.

H 7 * * *

H 16 * * 0

The format is as follows:

MINUTE (0-59), HOUR (0-23), DAY (1-31), MONTH (1-12), DAY OF THE WEEK (0-6)

The letter H, representing the word Hash can be inserted instead of any of the values. It will calculate the parameter based on the hash code of you project name.

This is so that if you are building several projects on your build machine at the same time, let’s say midnight each day, they do not all start their build execution at the same time. Each project starts its execution at a different minute depending on its hash code.

You can also specify the value to be between numbers, i.e. H(0,30) will return the hash code of the project where the possible hashes are 0-30.

Examples:

1. Start build daily at 08:30 in the morning, Monday - Friday: 30 08 * * 1-5

2. Weekday daily build twice a day, at lunchtime 12:00 and midnight 00:00, Sunday to Thursday: 00 0,12 * * 0-4

3. Start build daily in the late afternoon between 4:00 p.m. - 4:59 p.m. or 16:00 -16:59 depending on the projects hash: H 16 * * 1-5

4. Start build at midnight: @midnight or start build at midnight, every Saturday: 59 23 * * 6

5. Every first of every month between 2:00 a.m. - 02:30 a.m.: H(0,30) 02 01 * *

*/5 * * * * means every 5 minutes

5 * * * * means the 5th minute of every hour
