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).

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)

AddFlags adds flags for a specific APIServer to the specified 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 ...GroupRegisty) []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.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`.
	DisablePlugins []string
	// ConfigFile is the file path with admission control configuration.

	// Decorators is a list of admission decorator to wrap around the admission plugins
	Decorators admission.Decorators
}

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.

) error

ApplyTo adds the admission chain to the server configuration. In case admission plugin names were not provided by a cluster-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:

	// paths or end in * in which case prefix-match is applied. A leading / is optional.
	AlwaysAllowPaths []string

	// AlwaysAllowGroups are groups which are allowed to take any actions.  In kube, this is system:masters.
	AlwaysAllowGroups []string
}

DelegatingAuthorizationOptions provides an easy way for composing API servers to delegate their authorization to the root kube API server. WARNING: never assume that every authenticated incoming request already does authorization. 

The aggregator in the kube API server does this today, but this behaviour is not
guaranteed in the future.
