Codecs provides access to encoding and decoding for the scheme.
var Codecs = serializer.NewCodecFactory(Scheme)
Scheme is the runtime.Scheme to which all supported kubeadm ComponentConfig API types are registered.
var Scheme = runtime.NewScheme()
func AddToScheme(scheme *runtime.Scheme)
AddToScheme builds the kubeadm ComponentConfig scheme using all known ComponentConfig versions.
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(clusterCfg *kubeadmapi.ClusterConfiguration, localAPIEndpoint *kubeadmapi.APIEndpoint, nodeRegOpts *kubeadmapi.NodeRegistrationOptions)
Default sets up defaulted component configs in the supplied ClusterConfiguration
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(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(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(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(cm *v1.ConfigMap)
SignConfigMap calculates the supplied config map checksum and annotates it with it
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(cm *v1.ConfigMap) bool
VerifyConfigMapSignature returns true if the config map has checksum annotation and it matches; false otherwise
UnsupportedConfigVersionError is a special error type returned whenever we encounter too old config version
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
}
func (err *UnsupportedConfigVersionError) Error() string
Error implements the standard Golang error interface for UnsupportedConfigVersionError
UnsupportedConfigVersionsErrorMap is a cumulative version of the UnsupportedConfigVersionError type
type UnsupportedConfigVersionsErrorMap map[string]*UnsupportedConfigVersionError
func (errs UnsupportedConfigVersionsErrorMap) Error() string
Error implements the standard Golang error interface for UnsupportedConfigVersionsErrorMap
