Types

type ConcurrencyPolicy

type ConcurrencyPolicy string

ConcurrencyPolicy describes how the job will be handled. Only one of the following concurrent policies may be specified. If none of the following policies is specified, the default one is AllowConcurrent. +kubebuilder:validation:Enum=Allow;Forbid;Replace

const (
	// AllowConcurrent allows CronJobs to run concurrently.
	AllowConcurrent ConcurrencyPolicy = "Allow"

	// ForbidConcurrent forbids concurrent runs, skipping next run if previous
	// hasn't finished yet.
	ForbidConcurrent ConcurrencyPolicy = "Forbid"

	// ReplaceConcurrent cancels currently running job and replaces it with a new one.
	ReplaceConcurrent ConcurrencyPolicy = "Replace"
)

ISSUE: none of these docs (on the ConcurrencyPolicy constants) are exposed in any final product ISSUE: these can easily get out of sync with the validation on the type above

type CronJob

type CronJob struct {
	metav1.TypeMeta   `json:",inline"`
	metav1.ObjectMeta `json:"metadata,omitempty"`

	Spec   CronJobSpec   `json:"spec,omitempty"`
	Status CronJobStatus `json:"status,omitempty"`
}

CronJob is the Schema for the cronjobs API

type CronJobList

type CronJobList struct {
	metav1.TypeMeta `json:",inline"`
	metav1.ListMeta `json:"metadata,omitempty"`
	Items           []CronJob `json:"items"`
}

CronJobList contains a list of CronJob

type CronJobSpec

type CronJobSpec struct {

	// The schedule in Cron format, see https://en.wikipedia.org/wiki/Cron.
	Schedule string `json:"schedule"`

	// 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.
	// +optional
	StartingDeadlineSeconds *int64 `json:"startingDeadlineSeconds,omitempty"`

	// 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
	// +optional
	ConcurrencyPolicy ConcurrencyPolicy `json:"concurrencyPolicy,omitempty"`

	// This flag tells the controller to suspend subsequent executions, it does
	// not apply to already started executions.
	// +optional
	// +default=false
	Suspend *bool `json:"suspend,omitempty"`

	// Specifies the job that will be created when executing a CronJob.
	JobTemplate batchv1beta1.JobTemplateSpec `json:"jobTemplate"`

	// The number of successful finished jobs to retain.
	// This is a pointer to distinguish between explicit zero and not specified.
	// +optional
	// +default=3
	SuccessfulJobsHistoryLimit *int32 `json:"successfulJobsHistoryLimit,omitempty"`

	// The number of failed finished jobs to retain.
	// This is a pointer to distinguish between explicit zero and not specified.
	// +optional
	// +default=1
	FailedJobsHistoryLimit *int32 `json:"failedJobsHistoryLimit,omitempty"`
}

CronJobSpec defines the desired state of CronJob

type CronJobStatus

type CronJobStatus struct {
	// A list of pointers to currently running jobs.
	// +optional
	Active []corev1.ObjectReference `json:"active,omitempty"`

	// Information when was the last time the job was successfully scheduled.
	// +optional
	LastScheduleTime *metav1.Time `json:"lastScheduleTime,omitempty"`
}

CronJobStatus defines the observed state of CronJob
