Description

CronJob represents the configuration of a single cron job.

Type

object

Specification

Property Type 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 meta/v1

Standard object’s metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

.spec

object

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

.status

object

CronJobStatus represents the current state of a cron job.

.spec
Description

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

Type

object

Required
  • schedule

  • jobTemplate

Property Type 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

failedJobsHistoryLimit

integer

The number of failed finished jobs to retain. This is a pointer to distinguish between explicit zero and not specified. Defaults to 1.

jobTemplate

object

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

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. This is a pointer to distinguish between explicit zero and not specified. 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.

.spec.jobTemplate
Description

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

Type

object

Property Type Description

metadata

ObjectMeta meta/v1

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

object

JobSpec describes how the job execution will look like.

.spec.jobTemplate.spec
Description

JobSpec describes how the job execution will look like.

Type

object

Required
  • template

Property Type Description

activeDeadlineSeconds

integer

Specifies the duration in seconds relative to the startTime that the job may be active before the system tries to terminate it; value must be positive integer

backoffLimit

integer

Specifies the number of retries before marking this job failed. Defaults to 6

completions

integer

Specifies the desired number of successfully finished pods the job should be run with. Setting to nil means that the success of any pod signals the success of all pods, and allows parallelism to have any positive value. Setting to 1 means that parallelism is limited to 1 and the success of that pod signals the success of the job. More info: https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/

manualSelector

boolean

manualSelector controls generation of pod labels and pod selectors. Leave manualSelector unset unless you are certain what you are doing. When false or unset, the system pick labels unique to this job and appends those labels to the pod template. When true, the user is responsible for picking unique labels and specifying the selector. Failure to pick a unique label may cause this and other jobs to not function correctly. However, You may see manualSelector=true in jobs that were created with the old extensions/v1beta1 API. More info: https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/#specifying-your-own-pod-selector

parallelism

integer

Specifies the maximum desired number of pods the job should run at any given time. The actual number of pods running in steady state will be less than this number when ((.spec.completions - .status.successful) < .spec.parallelism), i.e. when the work left to do is less than max parallelism. More info: https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/

selector

LabelSelector meta/v1

A label query over pods that should match the pod count. Normally, the system sets this field for you. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors

template

PodTemplateSpec core/v1

Describes the pod that will be created when executing a job. More info: https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/

ttlSecondsAfterFinished

integer

ttlSecondsAfterFinished limits the lifetime of a Job that has finished execution (either Complete or Failed). If this field is set, ttlSecondsAfterFinished after the Job finishes, it is eligible to be automatically deleted. When the Job is being deleted, its lifecycle guarantees (e.g. finalizers) will be honored. If this field is unset, the Job won’t be automatically deleted. If this field is set to zero, the Job becomes eligible to be deleted immediately after it finishes. This field is alpha-level and is only honored by servers that enable the TTLAfterFinished feature.

.status
Description

CronJobStatus represents the current state of a cron job.

Type

object

Property Type Description

active

array (ObjectReference core/v1)

A list of pointers to currently running jobs.

lastScheduleTime

Time meta/v1

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