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).

	// ModeBatch indicates that the audit backend should buffer audit events

Types

type APIEnablementOptions 

type APIEnablementOptions struct {
	RuntimeConfig cliflag.ConfigurationMap
}

APIEnablementOptions contains the options for which resources to turn on and off. Given small aggregated API servers, this option isn't required for "normal" API servers

func NewAPIEnablementOptions 

func NewAPIEnablementOptions() *APIEnablementOptions

func (*APIEnablementOptions) AddFlags 

func (s *APIEnablementOptions) AddFlags(fs *pflag.FlagSet)

func (*APIEnablementOptions) ApplyTo 

func (s *APIEnablementOptions) ApplyTo(c *server.Config, defaultResourceConfig *serverstore.ResourceConfig, registry resourceconfig.GroupVersionRegistry) error

ApplyTo override MergedResourceConfig with defaults and registry

func (*APIEnablementOptions) Validate 

func (s *APIEnablementOptions) Validate(registries ...GroupRegistry) []error

Validate validates RuntimeConfig with a list of registries. Usually this list only has one element, the apiserver registry of the process. But in the advanced (and usually not recommended) case of delegated apiservers there can be more. Validate will filter out the known groups of each registry. If anything is left over after that, an error is returned.

type AdmissionOptions 

type AdmissionOptions struct {
	// RecommendedPluginOrder holds an ordered list of plugin names we recommend to use by default
	RecommendedPluginOrder []string
	// DefaultOffPlugins is a set of plugin names that is disabled by default
	DefaultOffPlugins sets.Set[string]

	// EnablePlugins indicates plugins to be enabled passed through `--enable-admission-plugins`.
	EnablePlugins []string
	// DisablePlugins indicates plugins to be disabled passed through `--disable-admission-plugins`.

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.

ServerRunOptions contains the options while running a generic api server.

func NewServerRunOptions 

func NewServerRunOptions() *ServerRunOptions

func NewServerRunOptionsForComponent added in v0.31.0 

func NewServerRunOptionsForComponent(componentName string, componentGlobalsRegistry utilversion.ComponentGlobalsRegistry) *ServerRunOptions

func (*ServerRunOptions) AddUniversalFlags 

func (s *ServerRunOptions) AddUniversalFlags(fs *pflag.FlagSet)

AddUniversalFlags adds flags for a specific APIServer to the specified FlagSet

func (*ServerRunOptions) ApplyTo 

func (s *ServerRunOptions) ApplyTo(c *server.Config) error

ApplyTo applies the run options to the method receiver and returns self

func (*ServerRunOptions) Complete added in v0.31.0 

func (s *ServerRunOptions) Complete() error

Complete fills missing fields with defaults.

func (*ServerRunOptions) DefaultAdvertiseAddress 

func (s *ServerRunOptions) DefaultAdvertiseAddress(secure *SecureServingOptions) error

DefaultAdvertiseAddress sets the field AdvertiseAddress if unset. The field will be set based on the SecureServingOptions.

func (*ServerRunOptions) Validate 

func (s *ServerRunOptions) Validate() []error

Validate checks validation of ServerRunOptions

type SimpleStorageFactory added in v0.26.0 

type SimpleStorageFactory struct {
	StorageConfig storagebackend.Config
}

SimpleStorageFactory provides a StorageFactory implementation that should be used when different resources essentially share the same storage config (as defined by the given storagebackend.Config). It assumes the resources are stored at a path that is purely based on the schema.GroupResource. Users that need flexibility and per resource overrides should use DefaultStorageFactory instead.

func (*SimpleStorageFactory) Backends added in v0.26.0 

func (s *SimpleStorageFactory) Backends() []serverstorage.Backend

func (*SimpleStorageFactory) Configs added in v0.26.7 

func (s *SimpleStorageFactory) Configs() []storagebackend.Config

func (*SimpleStorageFactory) NewConfig added in v0.26.0 

func (s *SimpleStorageFactory) NewConfig(resource schema.GroupResource, example runtime.Object) (*storagebackend.ConfigForResource, error)

func (*SimpleStorageFactory) ResourcePrefix added in v0.26.0 

func (s *SimpleStorageFactory) ResourcePrefix(resource schema.GroupResource) string

type StorageFactoryRestOptionsFactory 

type StorageFactoryRestOptionsFactory struct {
	Options        EtcdOptions
	StorageFactory serverstorage.StorageFactory
}

func (*StorageFactoryRestOptionsFactory) GetRESTOptions 

func (f *StorageFactoryRestOptionsFactory) GetRESTOptions(resource schema.GroupResource, example runtime.Object) (generic.RESTOptions, error)

type TracingOptions added in v0.22.0 

type TracingOptions struct {
	// ConfigFile is the file path with api-server tracing configuration.
	ConfigFile string
}

TracingOptions contain configuration options for tracing exporters

func NewTracingOptions added in v0.22.0 

func NewTracingOptions() *TracingOptions

NewTracingOptions creates a new instance of TracingOptions

func (*TracingOptions) AddFlags added in v0.22.0 

func (o *TracingOptions) AddFlags(fs *pflag.FlagSet)

AddFlags adds flags related to tracing to the specified FlagSet

func (*TracingOptions) ApplyTo added in v0.22.0 

func (o *TracingOptions) ApplyTo(es *egressselector.EgressSelector, c *server.Config) error

ApplyTo fills up Tracing config with options.

func (*TracingOptions) Validate added in v0.22.0 

func (o *TracingOptions) Validate() (errs []error)

Validate verifies flags passed to TracingOptions.
