Constants

const GroupName = "batch"

GroupName is the group name use in this package

const JobTrackingFinalizer = "batch.kubernetes.io/job-tracking"

JobTrackingFinalizer is a finalizer for Job's pods. It prevents them from being deleted before being accounted in the Job status. The apiserver and job controller use this string as a Job annotation, to mark Jobs that are being tracked using pod finalizers. Two releases after the JobTrackingWithFinalizers graduates to GA, JobTrackingFinalizer will no longer be used as a Job annotation.

	// 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,

	// Job get an associated completion index from 0 to (.spec.completions - 1),
	// available in the annotation batch.kubernetes.io/job-completion-index.
	// The Job is considered complete when there is one successfully completed Pod
	// for each index.
	// When value is `Indexed`, .spec.completions must be specified and
	// `.spec.parallelism` must be less than or equal to 10^5.
	// In addition, The Pod name takes the form
	// `$(job-name)-$(index)-$(random-string)`,
	// the Pod hostname takes the form `$(job-name)-$(index)`.
	//
	// More completion modes can be added in the future.
	// If the Job controller observes a mode that it doesn't recognize, which
	// is possible during upgrades due to version skew, the controller
	// skips updates for the Job.
	// +optional
	CompletionMode *CompletionMode

	// Suspend specifies whether the Job controller should create Pods or not. If
	// a Job is created with suspend set to true, no Pods are created by the Job
	// controller. If a Job is suspended after creation (i.e. the flag goes from
	// false to true), the Job controller will delete all active Pods associated
	// with this Job. Users must design their workload to gracefully handle this.
	// Suspending a Job will reset the StartTime field of the Job, effectively
	// resetting the ActiveDeadlineSeconds timer too. Defaults to false.

	CompletedIndexes string

	// UncountedTerminatedPods holds the UIDs of Pods that have terminated but
	// the job controller hasn't yet accounted for in the status counters.
	//
	// The job controller creates pods with a finalizer. When a pod terminates
	// (succeeded or failed), the controller does three steps to account for it
	// in the job status:
	// (1) Add the pod UID to the corresponding array in this field.
	// (2) Remove the pod finalizer.
	// (3) Remove the pod UID from the array while increasing the corresponding
	//     counter.
	//
	// This field is beta-level. The job controller only makes use of this field
	// when the feature gate JobTrackingWithFinalizers is enabled (enabled
