8. Scheduling Jenkins Jobs for a specific time: To setup an schedule for a job/project due to build and execute the test we need to update our ‘Build Triggers’ in Jenkins. Go to the Project>Configure>Select ‘Build Periodically’ under Build Triggers and update/type our schedule (ex: 30  2 *  *  *  )as per we need as bellow process and Save:

  • MINUTES Minutes in one hour (0-59)
  • HOURS Hours in one day (0-23)
  • DAYMONTH Day in a month (1-31)
  • MONTH Month in a year (1-12)
  • DAYWEEK Day of the week (0-7) where 0 and 7 are sunday

Since a few versions, Jenkins add a new parameter, H : (extract from the jenkins code documentation). To allow periodically scheduled tasks to produce even load on the system, the symbol H (for “hash”) 0 (zero) and * should be used wherever possible.

Note : * means every day/every month/every year. 0 means Zero th minute/hour . H  means any or between time

Examples 1:  The following are the main 5 parameters to set an schedule: M  H  D  M  DAYWeek 0    7 *  *  *    (The job will run 0th minute at 7am every day/month/year ) 0    0 * * *   (The job will spike 0th minute and 0th hour, means at midnight every day) 30  2 *  *  *  (The job will run 2.30am on every day/month/year)

Example 2 : H H(3-4) * * *  : A job which runs every Day of the week, every Month in a year , every Day in a month at a time between 3 – 4 am in the morning at any minute.

Example 3 : H (30 -45) 3 * * * : A job which runs every Day of the week, every Month in a year , every Day in a month at 3 am in the morning between 30 -45 minutes.

Example 4 : */5 * * * * : If you want to schedule your build every 5 minutes, this will do the job

Example 5 : 0 8 * * * : schedule your build every day at 8h 00, this will do the job
