CronJobSpec

Description

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

Properties

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

failedJobsHistoryLimit integer (int32)

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

jobTemplate JobTemplateSpec required

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

schedule string required

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

startingDeadlineSeconds integer (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.

successfulJobsHistoryLimit integer (int32)

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

suspend boolean

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

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.
