Functions

func FilterHPAs

func FilterHPAs(hpas []autoscalingv2.HorizontalPodAutoscaler) []autoscalingv2.HorizontalPodAutoscaler

FilterHPAs filters out the HorizontalPodAutoscalers to be kept and returns all the HorizontalPodAutoscalers to be deleted. The filtered-out HorizontalPodAutoscalers is decided as follows: 1. creationTimestamp (older is better)

func FilterNone

func FilterNone[T any](objs []T) []T

FiltenNone filter nothing, that is it returns the same slice as provided.

func FilterPodDisruptionBudgets

func FilterPodDisruptionBudgets(pdbs []policyv1.PodDisruptionBudget) []policyv1.PodDisruptionBudget

FilterPodDisruptionBudgets filters out the PodDisruptionBudgets to be kept and returns all the PodDisruptionBudgets to be deleted. The filtered-out PodDisruptionBudget is decided as follows: 1. creationTimestamp (older is better)

func ReduceClusterRoleBindings

func ReduceClusterRoleBindings(ctx context.Context, k8sClient client.Client, clusterRoleBindings []rbacv1.ClusterRoleBinding) error

ReduceClusterRoleBindings detects the best ClusterRoleBinding in the set and deletes all the others.

func ReduceClusterRoles

func ReduceClusterRoles(ctx context.Context, k8sClient client.Client, clusterRoles []rbacv1.ClusterRole) error

ReduceClusterRoles detects the best ClusterRole in the set and deletes all the others.

func ReduceDataPlanes

func ReduceDataPlanes(ctx context.Context, k8sClient client.Client, dataplanes []operatorv1beta1.DataPlane) error

ReduceNetworkPolicies detects the best NetworkPolicy in the set and deletes all the others.

func ReducePodDisruptionBudgets

func ReducePodDisruptionBudgets(ctx context.Context, k8sClient client.Client, pdbs []policyv1.PodDisruptionBudget, filter PDBFilterFunc) error

ReducePodDisruptionBudgets detects the best PodDisruptionBudget in the set and deletes all the others.

func ReduceSecrets

func ReduceSecrets(ctx context.Context, k8sClient client.Client, secrets []corev1.Secret, preDeleteHooks ...PreDeleteHook) error

ReduceSecrets detects the best secret in the set and deletes all the others. It accepts optional preDeleteHooks which are executed before every Secret delete operation.
