CronJob [batch/v1beta1]

    CronJob represents the configuration of a single cron job.

    Type

    .spec

    Description

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

    Type

    object

    Required

    • schedule

    PropertyTypeDescription

    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

    PropertyTypeDescription

    metadata

    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
    PropertyTypeDescription

    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:

    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:

    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:

    template

    PodTemplateSpec core/v1

    Describes the pod that will be created when executing a job. More info:

    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

    PropertyTypeDescription

    active

    array (ObjectReference core/v1)

    A list of pointers to currently running jobs.

    lastScheduleTime

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

    Table 1. Global guery parameters
    ParameterTypeDescription

    allowWatchBookmarks

    boolean

    allowWatchBookmarks requests watch events with type “BOOKMARK”. Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server’s discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored. If the feature gate WatchBookmarks is not enabled in apiserver, this field is ignored.

    string

    The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the “next key”.

    This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.

    fieldSelector

    string

    A selector to restrict the list of returned objects by their fields. Defaults to everything.

    labelSelector

    string

    A selector to restrict the list of returned objects by their labels. Defaults to everything.

    limit

    integer

    limit is a maximum number of responses to return for a list call. If more items exist, the server will set the continue field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true.

    The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.

    pretty

    string

    If ‘true’, then the output is pretty printed.

    string

    resourceVersion sets a constraint on what resource versions a request may be served from. See for details.

    Defaults to unset

    resourceVersionMatch

    string

    resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details.

    Defaults to unset

    timeoutSeconds

    integer

    Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

    watch

    boolean

    Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

    orphanDependents

    boolean

    Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the “orphan” finalizer will be added to/removed from the object’s finalizers list. Either this field or PropagationPolicy may be set, but not both.

    propagationPolicy

    string
