Overview

package options is the public flags and options used by a generic api server. It takes a minimal set of dependencies and does not reference implementations, in order to ensure it may be reused by multiple components (such as CLI commands that wish to generate or validate config).

Functions

func ParseWatchCacheSizes 

func ParseWatchCacheSizes(cacheSizes []string) (map[schema.GroupResource]int, error)

ParseWatchCacheSizes turns a list of cache size values into a map of group resources to requested sizes.

func WriteWatchCacheSizes 

func WriteWatchCacheSizes(watchCacheSizes map[schema.GroupResource]int) ([]string, error)

Types

type AdmissionOptions 

type AdmissionOptions struct {
	// RecommendedPluginOrder holds an ordered list of plugin names we recommend to use by default
	RecommendedPluginOrder []string
	// DefaultOffPlugins a list of plugin names that should be disabled by default
	DefaultOffPlugins []string
	PluginNames       []string
	ConfigFile        string
	Plugins           *admission.Plugins
}

AdmissionOptions holds the admission options

func NewAdmissionOptions 

func NewAdmissionOptions() *AdmissionOptions

NewAdmissionOptions creates a new instance of AdmissionOptions Note: 

In addition it calls RegisterAllAdmissionPlugins to register
all generic 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 

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

AddFlags adds flags related to admission for a specific APIServer to the specified FlagSet

func (*AdmissionOptions) ApplyTo 

func (a *AdmissionOptions) ApplyTo(c *server.Config, informers informers.SharedInformerFactory, pluginInitializers ...admission.PluginInitializer) error

ApplyTo adds the admission chain to the server configuration. In case admission plugin names were not provided by a custer-admin they will be prepared from the recommended/default values. In addition the method lazily initializes a generic plugin that is appended to the list of pluginInitializers note this method uses: 

genericconfig.LoopbackClientConfig
genericconfig.SharedInformerFactory
genericconfig.Authorizer
