syncset

Documentation

Overview

Package syncset provides a type to map LabelSelectors to arbitrary objects and render the minimal set of SelectorSyncSets based on the LabelSelectors. The idea is to use it as a replacement for map[metav1.LabelSelector]runtime.RawExtension. A map cannot be used because metav1.LabelSelector cannot be used as a key in a map. This implementation uses reflect.DeepEqual to compare map keys.

Functions

func Encode

func Encode(obj interface{}) []byte

func EncodeAndFixDaemonset

func EncodeAndFixDaemonset(ds *v1.DaemonSet) ([]byte, error)

This is needed to override the omitempty on serviceAccount and serviceAccountName which otherwise means we can't nullify them in the SelectorSyncSet

func EncodeMutatingAndFixCA

func EncodeMutatingAndFixCA(vw admissionregv1.MutatingWebhookConfiguration) ([]byte, error)

func EncodeValidatingAndFixCA

func EncodeValidatingAndFixCA(vw admissionregv1.ValidatingWebhookConfiguration) ([]byte, error)

Types

type SyncSetResourcesByLabelSelector

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

SyncSetResourcesByLabelSelector is a mapping data structure. It uses metav1.LabelSelector as key and runtime.RawExtension as value. The builtin map type cannot be used because metav1.LabelSelector cannot be used as key.

func (*SyncSetResourcesByLabelSelector) Add

func (s *SyncSetResourcesByLabelSelector) Add(key metav1.LabelSelector, object runtime.RawExtension)

Add adds a resources to a SyncSetResourcesByLabelSelector object

func (*SyncSetResourcesByLabelSelector) Get

func (s *SyncSetResourcesByLabelSelector) Get(key metav1.LabelSelector) *mapEntry

Get returns a single entry based on the passed key. If none exists, it returns nil

func (*SyncSetResourcesByLabelSelector) RenderSelectorSyncSets

func (s *SyncSetResourcesByLabelSelector) RenderSelectorSyncSets(labels map[string]string) []runtime.RawExtension

RenderSelectorSyncSets renders a minimal set of SelectorSyncSets based on the LabelSelectors existing in the SyncSetResourcesByLabelSelector object
