Types

type MutatingWebhook

type MutatingWebhook struct {
	*admission.Handler
	// contains filtered or unexported fields
}

func NewMutatingWebhook

func NewMutatingWebhook(configFile io.Reader) (*MutatingWebhook, error)

NewMutatingWebhook returns a generic admission webhook plugin.

func (*MutatingWebhook) Admit

func (a *MutatingWebhook) Admit(attr admission.Attributes) error

Admit makes an admission decision based on the request attributes.

func (*MutatingWebhook) SetAuthenticationInfoResolverWrapper

func (a *MutatingWebhook) SetAuthenticationInfoResolverWrapper(wrapper config.AuthenticationInfoResolverWrapper)

TODO find a better way wire this, but keep this pull small for now.

func (*MutatingWebhook) SetExternalKubeClientSet

func (a *MutatingWebhook) SetExternalKubeClientSet(client clientset.Interface)

WantsExternalKubeClientSet defines a function which sets external ClientSet for admission plugins that need it

func (*MutatingWebhook) SetExternalKubeInformerFactory

func (a *MutatingWebhook) SetExternalKubeInformerFactory(f informers.SharedInformerFactory)

SetExternalKubeInformerFactory implements the WantsExternalKubeInformerFactory interface.

func (*MutatingWebhook) SetScheme

func (a *MutatingWebhook) SetScheme(scheme *runtime.Scheme)

SetScheme sets a serializer(NegotiatedSerializer) which is derived from the scheme

func (*MutatingWebhook) SetServiceResolver

func (a *MutatingWebhook) SetServiceResolver(sr config.ServiceResolver)

SetServiceResolver sets a service resolver for the webhook admission plugin. Passing a nil resolver does not have an effect, instead a default one will be used.

func (*MutatingWebhook) ValidateInitialization

func (a *MutatingWebhook) ValidateInitialization() error

ValidateInitialization implements the InitializationValidator interface.

type WebhookSource

type WebhookSource interface {
	Run(stopCh <-chan struct{})
	Webhooks() (*v1beta1.MutatingWebhookConfiguration, error)
}
