Types

type ExtensionCondition

type ExtensionCondition struct {
	Condition          gardencorev1beta1.Condition
	ExtensionType      string
	ExtensionName      string
	ExtensionNamespace string
	LastHeartbeatTime  *metav1.MicroTime
}

ExtensionCondition contains information about the extension type, name, namespace and the respective condition object.

type HealthChecker

type HealthChecker struct {
	// contains filtered or unexported fields
}

HealthChecker contains the condition thresholds.

func NewHealthChecker

func NewHealthChecker(
	reader client.Reader,
	clock clock.Clock,
	conditionThresholds map[gardencorev1beta1.ConditionType]time.Duration,
	lastOperation *gardencorev1beta1.LastOperation,
) *HealthChecker

NewHealthChecker creates a new health checker.

func (*HealthChecker) CheckControlPlane

func (b *HealthChecker) CheckControlPlane(
	ctx context.Context,
	namespace string,
	requiredControlPlaneDeployments sets.Set[string],
	requiredControlPlaneEtcds sets.Set[string],
	condition gardencorev1beta1.Condition,
) (
	*gardencorev1beta1.Condition,
	error,
)

CheckControlPlane checks whether the given required control-plane component deployments and ETCDs are complete and healthy.

func (*HealthChecker) CheckExtensionCondition

func (b *HealthChecker) CheckExtensionCondition(condition gardencorev1beta1.Condition, extensionsConditions []ExtensionCondition, staleExtensionHealthCheckThreshold *metav1.Duration) *gardencorev1beta1.Condition

CheckExtensionCondition checks whether the conditions provided by extensions are healthy.

func (*HealthChecker) CheckLoggingControlPlane

func (b *HealthChecker) CheckLoggingControlPlane(
	ctx context.Context,
	namespace string,
	eventLoggingEnabled bool,
	valiEnabled bool,
	condition gardencorev1beta1.Condition,
) (
	*gardencorev1beta1.Condition,
	error,
)

CheckLoggingControlPlane checks whether the logging components are complete and healthy.

func (*HealthChecker) CheckManagedResource

func (b *HealthChecker) CheckManagedResource(condition gardencorev1beta1.Condition, mr *resourcesv1alpha1.ManagedResource, managedResourceProgressingThreshold *metav1.Duration) *gardencorev1beta1.Condition

CheckManagedResource checks the conditions of the given managed resource and reflects the state in the returned condition.

func (*HealthChecker) CheckMonitoringControlPlane

func (b *HealthChecker) CheckMonitoringControlPlane(
	ctx context.Context,
	namespace string,
	requiredMonitoringDeployments sets.Set[string],
	requiredMonitoringStatefulSets sets.Set[string],
	appsSelector labels.Selector,
	condition gardencorev1beta1.Condition,
) (
	*gardencorev1beta1.Condition,
	error,
)

CheckMonitoringControlPlane checks the monitoring components of the control-plane.

func (*HealthChecker) CheckNodes

func (b *HealthChecker) CheckNodes(condition gardencorev1beta1.Condition, nodes []corev1.Node, workerGroupName string, workerGroupKubernetesVersion *semver.Version) *gardencorev1beta1.Condition

CheckNodes whether the given nodes are ready and the version in the node status is of the same major-minor as given in 'workerGroupKubernetesVersion'.
