Functions

func AnyConfigFileAndDefaultsToInternal

func AnyConfigFileAndDefaultsToInternal(cfgPath string) (runtime.Object, error)

AnyConfigFileAndDefaultsToInternal reads either a InitConfiguration or JoinConfiguration and unmarshals it

func BytesToInternalConfig

func BytesToInternalConfig(b []byte) (*kubeadmapi.InitConfiguration, error)

BytesToInternalConfig converts a byte slice to an internal, defaulted and validated configuration object. The byte slice may contain one or many different YAML documents. These YAML documents are parsed one-by-one and well-known ComponentConfig GroupVersionKinds are stored inside of the internal InitConfiguration struct

func ConfigFileAndDefaultsToInternalConfig

func ConfigFileAndDefaultsToInternalConfig(cfgPath string, defaultversionedcfg *kubeadmapiv1alpha3.InitConfiguration) (*kubeadmapi.InitConfiguration, error)

ConfigFileAndDefaultsToInternalConfig takes a path to a config file and a versioned configuration that can serve as the default config If cfgPath is specified, defaultversionedcfg will always get overridden. Otherwise, the default config (often populated by flags) will be used. Then the external, versioned configuration is defaulted and converted to the internal type. Right thereafter, the configuration is defaulted again with dynamic values (like IP addresses of a machine, etc) Lastly, the internal config is validated and returned.

func DetectUnsupportedVersion

func DetectUnsupportedVersion(b []byte) error

DetectUnsupportedVersion reads YAML bytes, extracts the TypeMeta information and errors out with an user-friendly message if the API spec is too old for this kubeadm version

func FetchConfigFromFileOrCluster

func FetchConfigFromFileOrCluster(client clientset.Interface, w io.Writer, logPrefix, cfgPath string) (*kubeadmapi.InitConfiguration, error)

FetchConfigFromFileOrCluster fetches configuration required for upgrading your cluster from a file (which has precedence) or a ConfigMap in the cluster

func LowercaseSANs

func LowercaseSANs(sans []string)

LowercaseSANs can be used to force all SANs to be lowercase so it passes IsDNS1123Subdomain

func MarshalInitConfigurationToBytes

func MarshalInitConfigurationToBytes(cfg *kubeadmapi.InitConfiguration, gv schema.GroupVersion) ([]byte, error)

MarshalInitConfigurationToBytes marshals the internal InitConfiguration object to bytes. It writes the embedded ComponentConfiguration objects out as separate YAML documents

func MarshalKubeadmConfigObject

func MarshalKubeadmConfigObject(obj runtime.Object) ([]byte, error)

MarshalKubeadmConfigObject marshals an Object registered in the kubeadm scheme. If the object is a InitConfiguration, some extra logic is run

func NodeConfigFileAndDefaultsToInternalConfig

func NodeConfigFileAndDefaultsToInternalConfig(cfgPath string, defaultversionedcfg *kubeadmapiv1alpha3.JoinConfiguration) (*kubeadmapi.JoinConfiguration, error)

NodeConfigFileAndDefaultsToInternalConfig

func NormalizeKubernetesVersion

func NormalizeKubernetesVersion(cfg *kubeadmapi.InitConfiguration) error

NormalizeKubernetesVersion resolves version labels, sets alternative image registry if requested for CI builds, and validates minimal version that kubeadm SetInitDynamicDefaultssupports.

func SetInitDynamicDefaults

func SetInitDynamicDefaults(cfg *kubeadmapi.InitConfiguration) error

SetInitDynamicDefaults checks and sets configuration values for the InitConfiguration object

func SetJoinDynamicDefaults

func SetJoinDynamicDefaults(cfg *kubeadmapi.JoinConfiguration) error

SetJoinDynamicDefaults checks and sets configuration values for the JoinConfiguration object
