Types

type Factory

type Factory interface {
	genericclioptions.RESTClientGetter

	// DynamicClient returns a dynamic client ready for use
	DynamicClient() (dynamic.Interface, error)

	// KubernetesClientSet gives you back an external clientset
	KubernetesClientSet() (*kubernetes.Clientset, error)

	// Returns a RESTClient for accessing Kubernetes resources or an error.
	RESTClient() (*restclient.RESTClient, error)

	// NewBuilder returns an object that assists in loading objects from both disk and the server
	// and which implements the common patterns for CLI interactions with generic resources.
	NewBuilder() *resource.Builder

	// Returns a RESTClient for working with the specified RESTMapping or an error. This is intended
	// for working with arbitrary resources and is not guaranteed to point to a Kubernetes APIServer.
	ClientForMapping(mapping *meta.RESTMapping) (resource.RESTClient, error)

	// Returns a RESTClient for working with Unstructured objects.
	UnstructuredClientForMapping(mapping *meta.RESTMapping) (resource.RESTClient, error)

	// Returns a schema that can validate objects stored on disk.
	Validator(validate bool) (validation.Schema, error)

	// OpenAPISchema returns the schema openapi schema definition
	OpenAPISchema() (openapi.Resources, error)
}

Factory provides abstractions that allow the kubectl command to be extended across multiple types of resources and different API sets. The rings are here for a reason. In order for composers to be able to provide alternative factory implementations they need to provide low level pieces of *certain* functions so that when the factory calls back into itself it uses the custom version of the function. Rather than try to enumerate everything that someone would want to override we split the factory into rings, where each ring can depend on methods in an earlier ring, but cannot depend upon peer methods in its own ring. TODO: make the functions interfaces

func NewFactory

func NewFactory(clientGetter genericclioptions.RESTClientGetter) Factory

type MatchVersionFlags

type MatchVersionFlags struct {
	Delegate genericclioptions.RESTClientGetter

	RequireMatchedServerVersion bool
	// contains filtered or unexported fields
}

MatchVersionFlags is for setting the "match server version" function.

func NewMatchVersionFlags

func NewMatchVersionFlags(delegate genericclioptions.RESTClientGetter) *MatchVersionFlags

func (*MatchVersionFlags) AddFlags

func (f *MatchVersionFlags) AddFlags(flags *pflag.FlagSet)

func (*MatchVersionFlags) ToDiscoveryClient

func (f *MatchVersionFlags) ToDiscoveryClient() (discovery.CachedDiscoveryInterface, error)

func (*MatchVersionFlags) ToRESTConfig

func (f *MatchVersionFlags) ToRESTConfig() (*rest.Config, error)

ToRESTConfig implements RESTClientGetter. Returns a REST client configuration based on a provided path to a .kubeconfig file, loading rules, and config flag overrides. Expects the AddFlags method to have been called.

func (*MatchVersionFlags) ToRESTMapper

func (f *MatchVersionFlags) ToRESTMapper() (meta.RESTMapper, error)

RESTMapper returns a mapper.

func (*MatchVersionFlags) ToRawKubeConfigLoader

func (f *MatchVersionFlags) ToRawKubeConfigLoader() clientcmd.ClientConfig
