var ( // PlaceholderToken is only set statically to make kubeadm not randomize the token on every run PlaceholderToken = bootstraptokenv1.BootstrapToken{ Token: &bootstraptokenv1.BootstrapTokenString{ ID: "abcdef", Secret: "0123456789abcdef", }, } )
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
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 DefaultedInitConfiguration ¶ added in v1.14.0
func DefaultedInitConfiguration(versionedInitCfg *kubeadmapiv1.InitConfiguration, versionedClusterCfg *kubeadmapiv1.ClusterConfiguration) (*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 *kubeadmapiv1.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 DefaultedStaticInitConfiguration ¶ added in v1.21.0
func DefaultedStaticInitConfiguration() (*kubeadmapi.InitConfiguration, error)
DefaultedStaticInitConfiguration returns the internal InitConfiguration with static defaults.
func FetchInitConfigurationFromCluster ¶ added in v1.14.0
func FetchInitConfigurationFromCluster(client clientset.Interface, printer output.Printer, logPrefix string, newControlPlane, skipComponentConfigs bool) (*kubeadmapi.InitConfiguration, error)
FetchInitConfigurationFromCluster fetches configuration from a ConfigMap in the cluster
func GetNodeRegistration ¶ added in v1.24.0
func GetNodeRegistration(kubeconfigFile string, client clientset.Interface, nodeRegistration *kubeadmapi.NodeRegistrationOptions) error
GetNodeRegistration returns the nodeRegistration for the current node
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, versionedInitCfg *kubeadmapiv1.InitConfiguration, versionedClusterCfg *kubeadmapiv1.ClusterConfiguration) (*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) (*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 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
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
MigrateOldConfig migrates an old configuration from a byte slice into a new one (returned again as a byte slice). Only kubeadm kinds are migrated.
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 *[]bootstraptokenv1.BootstrapToken) error
SetBootstrapTokensDynamicDefaults checks and sets configuration values for the BootstrapTokens object
func SetClusterDynamicDefaults ¶ added in v1.12.0
func SetClusterDynamicDefaults(cfg *kubeadmapi.ClusterConfiguration, localAPIEndpoint *kubeadmapi.APIEndpoint, nodeRegOpts *kubeadmapi.NodeRegistrationOptions) 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 ValidateConfig ¶ added in v1.28.0
ValidateConfig takes a byte slice containing a kubeadm configuration and performs conversion to internal types and validation.
func VerifyAPIServerBindAddress ¶ added in v1.12.0
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.
