Variables

Codecs provides access to encoding and decoding for the scheme.

View Source
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 added in v1.19.0

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 added in v1.18.0

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

Default sets up defaulted component configs in the supplied ClusterConfiguration

func FetchFromCluster added in v1.18.0

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 FetchFromClusterWithLocalOverwrites added in v1.19.0

func FetchFromClusterWithLocalOverwrites(clusterCfg *kubeadmapi.ClusterConfiguration, client clientset.Interface, docmap kubeadmapi.DocumentMap) error

FetchFromClusterWithLocalOverwrites fetches component configs from a cluster and overwrites them locally with the ones present in the supplied document map. If any UnsupportedConfigVersionError are not handled by the configs in the document map, the function returns them all as a single UnsupportedConfigVersionsErrorMap. This function is normally called only in some specific cases during upgrade.

func FetchFromDocumentMap added in v1.18.0

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 added in v1.19.0

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

func SignConfigMap added in v1.19.0

func SignConfigMap(cm *v1.ConfigMap)

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

func Validate added in v1.18.0

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 added in v1.19.0

func VerifyConfigMapSignature(cm *v1.ConfigMap) bool

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

Types

type UnsupportedConfigVersionError added in v1.19.0

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 added in v1.19.0

Error implements the standard Golang error interface for UnsupportedConfigVersionError

type UnsupportedConfigVersionsErrorMap added in v1.19.0

type UnsupportedConfigVersionsErrorMap map[string]*UnsupportedConfigVersionError

UnsupportedConfigVersionsErrorMap is a cumulative version of the UnsupportedConfigVersionError type

func (UnsupportedConfigVersionsErrorMap) Error added in v1.19.0

Error implements the standard Golang error interface for UnsupportedConfigVersionsErrorMap
