Run a cron job once in N hours

Question

Kubernetes cron job has a feature where it can run a job a specified time.

I'm trying to have something where you can run a job every N hours. But i can't find any example or documentation to do so.

How do I go about this?

Answer 1

If you want your cron job to run every hour then you can do something like this:

You have to edit the crontab file, like:

crontab -e

There you add

0 13,14,15 *   *   *     /home/user/command

to execute your command at 13:00, 14:00 and 15:00. Also note that user has to be substituted with the user account the command is executed in.
