Variables

var Codecs = serializer.NewCodecFactory(Scheme)

Codecs provides access to encoding and decoding for the scheme.

var Scheme = runtime.NewScheme()

Scheme is the runtime.Scheme to which all supported kubeadm ComponentConfig API types are registered.

Functions

func AddToScheme

func AddToScheme(scheme *runtime.Scheme)

AddToScheme builds the kubeadm ComponentConfig scheme using all known ComponentConfig versions.

func ChecksumForConfigMap

func ChecksumForConfigMap(cm *v1.ConfigMap) string

ChecksumForConfigMap calculates a checksum for the supplied config map. The exact algorithm depends on hash and prefix parameters

func Default

func Default(clusterCfg *kubeadmapi.ClusterConfiguration, localAPIEndpoint *kubeadmapi.APIEndpoint, nodeRegOpts *kubeadmapi.NodeRegistrationOptions)

Default sets up defaulted component configs in the supplied ClusterConfiguration

func FetchFromCluster

func FetchFromCluster(clusterCfg *kubeadmapi.ClusterConfiguration, client clientset.Interface) error

FetchFromCluster attempts to fetch all known component configs from their config maps and store them in the supplied ClusterConfiguration

func FetchFromDocumentMap

func FetchFromDocumentMap(clusterCfg *kubeadmapi.ClusterConfiguration, docmap kubeadmapi.DocumentMap) error

FetchFromDocumentMap attempts to load all known component configs from a document map into the supplied ClusterConfiguration

func GetVersionStates

func GetVersionStates(clusterCfg *kubeadmapi.ClusterConfiguration, client clientset.Interface) ([]outputapiv1alpha3.ComponentConfigVersionState, error)

GetVersionStates returns a slice of ComponentConfigVersionState structs describing all supported component config groups that were identified on the cluster

func SignConfigMap

func SignConfigMap(cm *v1.ConfigMap)

SignConfigMap calculates the supplied config map checksum and annotates it with it

func Validate

func Validate(clusterCfg *kubeadmapi.ClusterConfiguration) field.ErrorList

Validate is a placeholder for performing a validation on an already loaded component configs in a ClusterConfiguration TODO: investigate if the function can be repurposed for validating component config via CLI

func VerifyConfigMapSignature

func VerifyConfigMapSignature(cm *v1.ConfigMap) bool

VerifyConfigMapSignature returns true if the config map has checksum annotation and it matches; false otherwise

Types

type UnsupportedConfigVersionError

type UnsupportedConfigVersionError struct {
	// OldVersion is the config version that is causing the problem
	OldVersion schema.GroupVersion

	// CurrentVersion describes the natively supported config version
	CurrentVersion schema.GroupVersion

	// Document points to the YAML/JSON document that caused the problem
	Document []byte
}

UnsupportedConfigVersionError is a special error type returned whenever we encounter too old config version

func (*UnsupportedConfigVersionError) Error

func (err *UnsupportedConfigVersionError) Error() string

Error implements the standard Golang error interface for UnsupportedConfigVersionError

type UnsupportedConfigVersionsErrorMap

type UnsupportedConfigVersionsErrorMap map[string]*UnsupportedConfigVersionError

UnsupportedConfigVersionsErrorMap is a cumulative version of the UnsupportedConfigVersionError type

func (UnsupportedConfigVersionsErrorMap) Error

func (errs UnsupportedConfigVersionsErrorMap) Error() string

Error implements the standard Golang error interface for UnsupportedConfigVersionsErrorMap
