Overview

Package status provides a generic way to report status and conditions for any resource of type client.Object.

The Reporter struct centralizes the management of status and condition updates for any resource type that implements client.Object. This approach consolidates the previously scattered updateStatus functions found in DSCI and DSC controllers into a single, reusable component.

Reporter handles the reporting of a resource's condition based on the operational state and errors encountered during processing. It uses a closure, DetermineCondition, defined by the developer to determine how conditions should be updated, particularly in response to errors. This closure is similar to its previous incarnation "update func(saved)", which appends the target object's conditions, with the only difference being access to an optional error to make changes in the condition to be reported based on the occurred error.

Example:

createReporter initializes a new status reporter for a DSCInitialization resource. It encapsulates the logic for updating the condition based on errors encountered during the resource's lifecycle operations.

func createReporter(cli client.Client, object *dsciv1.DSCInitialization, condition *conditionsv1.Condition) *status.Reporter[*dsciv1.DSCInitialization] {
	return status.NewStatusReporter[*dsciv1.DSCInitialization](
		cli,
		object,
		func(err error) status.SaveStatusFunc[*dsciv1.DSCInitialization] {
			return func(saved *dsciv1.DSCInitialization) {
				if err != nil {
					condition.Status = corev1.ConditionFalse
					condition.Message = err.Error()
					condition.Reason = status.CapabilityFailed
					var missingOperatorErr *feature.MissingOperatorError
					if errors.As(err, &missingOperatorErr) {
						condition.Reason = status.MissingOperatorReason
					}
				}
				conditionsv1.SetStatusCondition(&saved.Status.Conditions, *condition)
			}
		},
	)
}

doServiceMeshStuff manages the Service Mesh configuration process during DSCInitialization reconcile. It creates a reporter and reports any conditions derived from the service mesh configuration process.

func (r *DSCInitializationReconciler) doStdoServiceMeshStuffff(instance *dsciv1.DSCInitialization) error {
	reporter := createReporter(r.Client, instance, &conditionsv1.Condition{
		Type:    status.CapabilityServiceMesh,
		Status:  corev1.ConditionTrue,
		Reason:  status.ConfiguredReason,
		Message: "Service Mesh configured",
	})

	serviceMeshErr := createServiceMesh(instance)
	_, reportError := reporter.ReportCondition(serviceMeshErr)

	return multierror.Append(serviceMeshErr, reportError) // return all errors
}

Package status contains different conditions, phases and progresses, being used by DataScienceCluster and DSCInitialization's controller

Functions

func RemoveComponentCondition

func RemoveComponentCondition(conditions *[]conditionsv1.Condition, component string)

RemoveComponentCondition remove Condition of giving component.

func SetCompleteCondition

func SetCompleteCondition(conditions *[]conditionsv1.Condition, reason string, message string)

SetCompleteCondition sets the ConditionReconcileComplete to True and other Conditions to indicate that the reconciliation process has completed successfully.

func SetComponentCondition

func SetComponentCondition(conditions *[]conditionsv1.Condition, component string, reason string, message string, status corev1.ConditionStatus)

SetComponentCondition appends Condition Type with const ReadySuffix for given component when component finished reconcile.

func SetErrorCondition

func SetErrorCondition(conditions *[]conditionsv1.Condition, reason string, message string)

func SetExistingArgoCondition

func SetExistingArgoCondition(conditions *[]conditionsv1.Condition, reason, message string)

func SetProgressingCondition

func SetProgressingCondition(conditions *[]conditionsv1.Condition, reason string, message string)

SetProgressingCondition sets the ProgressingCondition to True and other conditions to false or Unknown. Used when we are just starting to reconcile, and there are no existing conditions.

func UpdateWithRetry

func UpdateWithRetry[T client.Object](ctx context.Context, cli client.Client, original T, update SaveStatusFunc[T]) (T, error)

UpdateWithRetry updates the status of object using passed function and retries on conflict.

Types

type DetermineCondition

type DetermineCondition[T client.Object] func(err error) SaveStatusFunc[T]

DetermineCondition is a function that allow to define how condition should be set. It can use err if available to set faulty condition. It should return a SaveStatusFunc which will be used to update the status of the object.

type Reporter

type Reporter[T client.Object] struct {
	// contains filtered or unexported fields
}

Reporter handles condition reporting for a given object. The logic of how the given condition should be calculated is defined by the determineCondition function.

func NewStatusReporter

func NewStatusReporter[T client.Object](cli client.Client, object T, determine DetermineCondition[T]) *Reporter[T]

NewStatusReporter creates r new Reporter with all required fields.

func (*Reporter[T]) ReportCondition

func (r *Reporter[T]) ReportCondition(optionalErr error) (T, error)

ReportCondition updates the status of the object using the determineCondition function.

type SaveStatusFunc

type SaveStatusFunc[T client.Object] func(saved T)

SaveStatusFunc is a function that allow to define custom logic of updating status of a concrete resource object.
