Functions

func BytesToInitConfiguration added in v1.14.0 

func BytesToInitConfiguration(b []byte, skipCRIDetect bool) (*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.ResolveBindAddress that also handles the case where no default routes were found and an IP for the API server could not be obtained.

func LoadInitConfigurationFromFile added in v1.14.0 

func LoadInitConfigurationFromFile(cfgPath string, opts LoadOrDefaultConfigurationOptions) (*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, opts LoadOrDefaultConfigurationOptions) (*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, versionedInitCfg *kubeadmapiv1.InitConfiguration, versionedClusterCfg *kubeadmapiv1.ClusterConfiguration, opts LoadOrDefaultConfigurationOptions) (*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, the versioned configs will always get overridden with the one in the file (specified by cfgPath). 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 *kubeadmapiv1.JoinConfiguration, opts LoadOrDefaultConfigurationOptions) (*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 LoadOrDefaultResetConfiguration added in v1.28.0 

func LoadOrDefaultResetConfiguration(cfgPath string, defaultversionedcfg *kubeadmapiv1.ResetConfiguration, opts LoadOrDefaultConfigurationOptions) (*kubeadmapi.ResetConfiguration, error)

LoadOrDefaultResetConfiguration 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 Lastly, the internal config is validated and returned.

func LoadResetConfigurationFromFile added in v1.28.0 

func LoadResetConfigurationFromFile(cfgPath string, opts LoadOrDefaultConfigurationOptions) (*kubeadmapi.ResetConfiguration, error)

LoadResetConfigurationFromFile loads versioned ResetConfiguration from file, converts it to internal, defaults and validates it

func LowercaseSANs added in v1.11.0 

func LowercaseSANs(sans []string)
