Functions

func DefaultOffAdmissionPlugins added in v1.10.0 

func DefaultOffAdmissionPlugins() sets.String

DefaultOffAdmissionPlugins get admission plugins off by default for kube-apiserver.

func NewSecureServingOptions 

func NewSecureServingOptions() *genericoptions.SecureServingOptionsWithLoopback

NewSecureServingOptions gives default values for the kube-apiserver which are not the options wanted by "normal" API servers running on the platform

func RegisterAllAdmissionPlugins added in v1.10.0 

func RegisterAllAdmissionPlugins(plugins *admission.Plugins)

RegisterAllAdmissionPlugins registers all admission plugins and sets the recommended plugins order.

Types

type AdmissionOptions added in v1.10.0 

type AdmissionOptions struct {
	// GenericAdmission holds the generic admission options.
	GenericAdmission *genericoptions.AdmissionOptions
	// DEPRECATED flag, should use EnabledAdmissionPlugins and DisabledAdmissionPlugins.
	// They are mutually exclusive, specify both will lead to an error.
	PluginNames []string
}

AdmissionOptions holds the admission options. It is a wrap of generic AdmissionOptions.

func NewAdmissionOptions added in v1.10.0 

func NewAdmissionOptions() *AdmissionOptions

NewAdmissionOptions creates a new instance of AdmissionOptions Note: 

In addition it calls RegisterAllAdmissionPlugins to register
all kube-apiserver admission plugins.

Provides the list of RecommendedPluginOrder that holds sane values
that can be used by servers that don't care about admission chain.
Servers that do care can overwrite/append that field after creation.

func (*AdmissionOptions) AddFlags added in v1.10.0 

func (a *AdmissionOptions) AddFlags(fs *pflag.FlagSet)

AddFlags adds flags related to admission for kube-apiserver to the specified FlagSet

func (*AdmissionOptions) ApplyTo added in v1.10.0 

func (a *AdmissionOptions) ApplyTo(
	c *server.Config,
	informers informers.SharedInformerFactory,
	kubeAPIServerClientConfig *rest.Config,
	features featuregate.FeatureGate,
	pluginInitializers ...admission.PluginInitializer,
) error

ApplyTo adds the admission chain to the server configuration. Kube-apiserver just call generic AdmissionOptions.ApplyTo.

func (*AdmissionOptions) Validate added in v1.10.0 

func (a *AdmissionOptions) Validate() []error

Validate verifies flags passed to kube-apiserver AdmissionOptions. Kube-apiserver verifies PluginNames and then call generic AdmissionOptions.Validate.
