CronJob

CronJob represents the configuration of a single cron job.

CronJobSpec

CronJobSpec describes how the job execution will look like and when it will actually run.

  • jobTemplate (JobTemplateSpec), required

    Specifies the job that will be created when executing a CronJob.

    JobTemplateSpec describes the data a Job should have when created from a template

  • schedule (string), required

    The schedule in Cron format, see https://en.wikipedia.org/wiki/Cron.

  • timeZone (string)

    The time zone name for the given schedule, see https://en.wikipedia.org/wiki/List_of_tz_database_time_zones. If not specified, this will default to the time zone of the kube-controller-manager process. The set of valid time zone names and the time zone offset is loaded from the system-wide time zone database by the API server during CronJob validation and the controller manager during execution. If no system-wide time zone database can be found a bundled version of the database is used instead. If the time zone name becomes invalid during the lifetime of a CronJob or due to a change in host configuration, the controller will stop creating new new Jobs and will create a system event with the reason UnknownTimeZone. More information can be found in https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/#time-zones This is beta field and must be enabled via the CronJobTimeZone feature gate.

  • concurrencyPolicy (string)

    Specifies how to treat concurrent executions of a Job. Valid values are: - "Allow" (default): allows CronJobs to run concurrently; - "Forbid": forbids concurrent runs, skipping next run if previous run hasn't finished yet; - "Replace": cancels currently running job and replaces it with a new one

  • startingDeadlineSeconds (int64)

    Optional deadline in seconds for starting the job if it misses scheduled time for any reason. Missed jobs executions will be counted as failed ones.

  • suspend (boolean)

    This flag tells the controller to suspend subsequent executions, it does not apply to already started executions. Defaults to false.

  • successfulJobsHistoryLimit (int32)

    The number of successful finished jobs to retain. Value must be non-negative integer. Defaults to 3.

  • failedJobsHistoryLimit (int32)

    The number of failed finished jobs to retain. Value must be non-negative integer. Defaults to 1.

CronJobStatus

CronJobStatus represents the current state of a cron job.

  • active ([]ObjectReference)

    Atomic: will be replaced during a merge

    A list of pointers to currently running jobs.

  • lastScheduleTime (Time)

    Information when was the last time the job was successfully scheduled.

    Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

  • lastSuccessfulTime (Time)

    Information when was the last time the job successfully completed.

    Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

CronJobList

CronJobList is a collection of cron jobs.
