Functions

func BytesToInitConfiguration added in v1.14.0

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

BytesToInitConfiguration converts a byte slice to an internal, defaulted and validated InitConfiguration object. The map may contain 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. The resulting InitConfiguration is then dynamically defaulted and validated prior to return.

func ChooseAPIServerBindAddress added in v1.12.0

func ChooseAPIServerBindAddress(bindAddress net.IP) (net.IP, error)

ChooseAPIServerBindAddress is a wrapper for netutil.ChooseBindAddress that also handles the case where no default routes were found and an IP for the API server could not be obatained.

func DefaultedInitConfiguration added in v1.14.0

func DefaultedInitConfiguration(defaultversionedcfg *kubeadmapiv1beta1.InitConfiguration) (*kubeadmapi.InitConfiguration, error)

DefaultedInitConfiguration takes a versioned init config (often populated by flags), defaults it and converts it into internal InitConfiguration

func DefaultedJoinConfiguration added in v1.14.0

func DefaultedJoinConfiguration(defaultversionedcfg *kubeadmapiv1beta1.JoinConfiguration) (*kubeadmapi.JoinConfiguration, error)

DefaultedJoinConfiguration takes a versioned JoinConfiguration (usually filled in by command line parameters), defaults it, converts it to internal and validates it

func FetchInitConfigurationFromCluster added in v1.14.0

func FetchInitConfigurationFromCluster(client clientset.Interface, w io.Writer, logPrefix string, newControlPlane bool) (*kubeadmapi.InitConfiguration, error)

FetchInitConfigurationFromCluster fetches configuration from a ConfigMap in the cluster

func GetClusterStatus added in v1.13.0

func GetClusterStatus(client clientset.Interface) (*kubeadmapi.ClusterStatus, error)

GetClusterStatus returns the kubeadm cluster status read from the kubeadm-config ConfigMap

func LoadInitConfigurationFromFile added in v1.14.0

func LoadInitConfigurationFromFile(cfgPath string) (*kubeadmapi.InitConfiguration, error)

LoadInitConfigurationFromFile loads a supported versioned InitConfiguration from a file, converts it into internal config, defaults it and verifies it.

func LoadJoinConfigurationFromFile added in v1.14.0

func LoadJoinConfigurationFromFile(cfgPath string) (*kubeadmapi.JoinConfiguration, error)

LoadJoinConfigurationFromFile loads versioned JoinConfiguration from file, converts it to internal, defaults and validates it

func LoadOrDefaultInitConfiguration added in v1.14.0

func LoadOrDefaultInitConfiguration(cfgPath string, defaultversionedcfg *kubeadmapiv1beta1.InitConfiguration) (*kubeadmapi.InitConfiguration, error)

LoadOrDefaultInitConfiguration 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 LoadOrDefaultJoinConfiguration added in v1.14.0

func LoadOrDefaultJoinConfiguration(cfgPath string, defaultversionedcfg *kubeadmapiv1beta1.JoinConfiguration) (*kubeadmapi.JoinConfiguration, error)

LoadOrDefaultJoinConfiguration 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 LowercaseSANs added in v1.11.0

func LowercaseSANs(sans []string)

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

func MarshalClusterConfigurationToBytes added in v1.12.0

func MarshalClusterConfigurationToBytes(clustercfg *kubeadmapi.ClusterConfiguration, gv schema.GroupVersion) ([]byte, error)

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

func MarshalInitConfigurationToBytes added in v1.12.0

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

MarshalInitConfigurationToBytes marshals the internal InitConfiguration object to bytes. It writes the embedded ClusterConfiguration object with ComponentConfigs out as separate YAML documents

func MarshalKubeadmConfigObject added in v1.12.0

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

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

func MigrateOldConfig added in v1.14.0

func MigrateOldConfig(oldConfig []byte) ([]byte, error)

MigrateOldConfig migrates an old configuration from a byte slice into a new one (returned again as a byte slice). Only kubeadm kinds are migrated. Others are silently ignored.

func NormalizeKubernetesVersion added in v1.9.0

func NormalizeKubernetesVersion(cfg *kubeadmapi.ClusterConfiguration) error

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

func SetAPIEndpointDynamicDefaults added in v1.12.0

func SetAPIEndpointDynamicDefaults(cfg *kubeadmapi.APIEndpoint) error

SetAPIEndpointDynamicDefaults checks and sets configuration values for the APIEndpoint object

func SetBootstrapTokensDynamicDefaults added in v1.12.0

func SetBootstrapTokensDynamicDefaults(cfg *[]kubeadmapi.BootstrapToken) error

SetBootstrapTokensDynamicDefaults checks and sets configuration values for the BootstrapTokens object

func SetClusterDynamicDefaults added in v1.12.0

func SetClusterDynamicDefaults(cfg *kubeadmapi.ClusterConfiguration, advertiseAddress string, bindPort int32) error

SetClusterDynamicDefaults checks and sets values for the ClusterConfiguration object

func SetInitDynamicDefaults

func SetInitDynamicDefaults(cfg *kubeadmapi.InitConfiguration) error

SetInitDynamicDefaults checks and sets configuration values for the InitConfiguration object

func SetJoinControlPlaneDefaults added in v1.13.0

func SetJoinControlPlaneDefaults(cfg *kubeadmapi.JoinControlPlane) error

SetJoinControlPlaneDefaults checks and sets configuration values for the JoinControlPlane object

func SetJoinDynamicDefaults added in v1.11.0

func SetJoinDynamicDefaults(cfg *kubeadmapi.JoinConfiguration) error

SetJoinDynamicDefaults checks and sets configuration values for the JoinConfiguration object

func SetNodeRegistrationDynamicDefaults added in v1.12.0

func SetNodeRegistrationDynamicDefaults(cfg *kubeadmapi.NodeRegistrationOptions, ControlPlaneTaint bool) error

SetNodeRegistrationDynamicDefaults checks and sets configuration values for the NodeRegistration object

func UnmarshalClusterStatus added in v1.14.0

func UnmarshalClusterStatus(data map[string]string) (*kubeadmapi.ClusterStatus, error)

UnmarshalClusterStatus takes raw ConfigMap.Data and converts it to a ClusterStatus object

func VerifyAPIServerBindAddress added in v1.12.0

func VerifyAPIServerBindAddress(address string) error

VerifyAPIServerBindAddress can be used to verify if a bind address for the API Server is 0.0.0.0, in which case this address is not valid and should not be used.
