fn metadata.withClusterName

withClusterName(clusterName)

"The name of the cluster which the object belongs to. This is used to distinguish resources with same name and namespace in different clusters. This field is not set anywhere right now and apiserver is going to ignore it if set in create or update request."

withCreationTimestamp(creationTimestamp)

"Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers."

fn metadata.withFinalizers

withFinalizers(finalizers)

"Must be empty before the object is deleted from the registry. Each entry is an identifier for the responsible component that will remove the entry from the list. If the deletionTimestamp of the object is non-nil, entries in this list can only be removed. Finalizers may be processed and removed in any order. Order is NOT enforced because it introduces significant risk of stuck finalizers. finalizers is a shared field, any actor with permission can reorder it. If the finalizer list is processed in order, then this can lead to a situation in which the component responsible for the first finalizer in the list is waiting for a signal (field value, external system, or other) produced by a component responsible for a finalizer later in the list, resulting in a deadlock. Without enforced ordering finalizers are free to order amongst themselves and are not vulnerable to ordering changes in the list."

fn metadata.withGenerateName

withGenerateName(generateName)

"GenerateName is an optional prefix, used by the server, to generate a unique name ONLY IF the Name field has not been provided. If this field is used, the name returned to the client will be different than the name passed. This value will also be combined with a unique suffix. The provided value has the same validation rules as the Name field, and may be truncated by the length of the suffix required to make the value unique on the server.\n\nIf this field is specified and the generated name exists, the server will NOT return a 409 - instead, it will either return 201 Created or 500 with Reason ServerTimeout indicating a unique name could not be found in the time allotted, and the client should retry (optionally after the time indicated in the Retry-After header).\n\nApplied only if Name is not specified.

obj spec.retryConstraint

"RetryConstraint defines the configuration for when to allow or prevent\nfurther retries to a target backend, by dynamically calculating a 'retry\nbudget'. This budget is calculated based on the percentage of incoming\ntraffic composed of retries over a given time interval. Once the budget\nis exceeded, additional retries will be rejected.\n\nFor example, if the retry budget interval is 10 seconds, there have been\n1000 active requests in the past 10 seconds, and the allowed percentage\nof requests that can be retried is 20% (the default), then 200 of those\nrequests may be composed of retries. Active requests will only be\nconsidered for the duration of the interval when calculating the retry\nbudget. Retrying the same original request multiple times within the\nretry budget interval will lead to each retry being counted towards\ncalculating the budget.\n\nConfiguring a RetryConstraint in BackendTrafficPolicy is compatible with\nHTTPRoute Retry settings for each HTTPRouteRule that targets the same\nbackend. While the HTTPRouteRule Retry stanza can specify whether a\nrequest will be retried, and the number of retry attempts each client\nmay perform, RetryConstraint helps prevent cascading failures such as\nretry storms during periods of consistent failures.\n\nAfter the retry budget has been exceeded, additional retries to the\nbackend MUST return a 503 response to the client.\n\nAdditional configurations for defining a constraint on retries MAY be\ndefined in the future.\n\nSupport: Extended"

obj spec.retryConstraint.minRetryRate

"MinRetryRate defines the minimum rate of retries that will be allowable\nover a specified duration of time.\n\nThe effective overall minimum rate of retries targeting the backend\nservice may be much higher, as there can be any number of clients which\nare applying this setting locally.\n\nThis ensures that requests can still be retried during periods of low\ntraffic, where the budget for retries may be calculated as a very low\nvalue.\n\nSupport: Extended"
