CronJob

CronJob represents the configuration of a single cron job.

Field	Description
`apiVersion` string	APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
`kind` string	Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
`metadata` ObjectMeta	Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
`spec` * CronJobSpec	Specification of the desired behavior of a cron job, including the schedule. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status
`status` CronJobStatus	Current status of a cron job. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status

CronJobSpec

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

Field	Description
`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 Possible enum values: - `"Allow"` allows CronJobs to run concurrently. - `"Forbid"` forbids concurrent runs, skipping next run if previous hasn't finished yet. - `"Replace"` cancels currently running job and replaces it with a new one.
`failedJobsHistoryLimit` integer	The number of failed finished jobs to retain. Value must be non-negative integer. Defaults to 1.
`jobTemplate` * JobTemplateSpec	Specifies the job that will be created when executing a CronJob.
`schedule` * string	The schedule in Cron format, see https://en.wikipedia.org/wiki/Cron.
`startingDeadlineSeconds` integer	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	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. More information can be found in https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/#time-zones

CronJobStatus

CronJobStatus represents the current state of a cron job.

Field	Description
`active` ObjectReference array	A list of pointers to currently running jobs.
`lastScheduleTime` Time	Information when was the last time the job was successfully scheduled.
`lastSuccessfulTime` Time	Information when was the last time the job successfully completed.

CronJobList

CronJobList is a collection of cron jobs.

Field	Description
`apiVersion` string	APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
`items` * CronJob array	items is the list of CronJobs.
`kind` string	Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
`metadata` ListMeta	Standard list metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

JobTemplateSpec

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

Field	Description
`metadata` ObjectMeta	Standard object's metadata of the jobs created from this template. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
`spec` JobSpec	Specification of the desired behavior of the job. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status
