Job and Cronjob

This chart deploys Job & CronJob. A Job is a controller object that represents a finite task and CronJob is used to schedule the creation of Jobs.

1. Job

A Job creates one or more Pods and will continue to retry execution of the Pods until a specified number of them successfully terminate. As pods successfully complete, the Job tracks the successful completions. When a specified number of successful completions is reached, the task (ie, Job) is complete. Deleting a Job will clean up the Pods it created. Suspeding a Job will delete its active Pods until the Job is resumed again.


kind: Job
    activeDeadlineSeconds: 120
    backoffLimit: 6
    completions: 1
    parallelism: 1
    suspend: false
    ttlSecondsAfterFinished: 100

2. CronJob

A CronJob creates jobs on a repeating schedule. One Cronjob object is like one line of a crontab (cron table) file. It runs a job periodically on a given schedule, written in Cron format. CronJobs are meant for performing regular scheduled actions such as backups, report generation, and so on. Each task must be configured to recur indefinitely (as an example: once a day / week / month). You can schedule the time within that interval when the job should start.


kind: CronJob
    concurrencyPolicy: Allow
    failedJobsHistoryLimit: 1
    restartPolicy: OnFailure
    schedule: 32 8 * * *
    startingDeadlineSeconds: 100
    successfulJobsHistoryLimit: 3
    suspend: false

Super-admins can lock keys in Job & CronJob deployment template to prevent non-super-admins from modifying those locked keys. Refer Lock Deployment Configuration to know more.
