Functions

func CreateConfigMap

func CreateConfigMap(cfg *kubeadmapi.MasterConfiguration, client clientset.Interface) error

CreateConfigMap creates a ConfigMap with the generic kubelet configuration. Used at "kubeadm init" and "kubeadm upgrade" time

func DownloadConfig

func DownloadConfig(kubeletKubeConfig string, kubeletVersion *version.Version) error

DownloadConfig downloads the kubelet configuration from a ConfigMap and writes it to disk. Used at "kubeadm join" time

func EnableDynamicConfigForNode

func EnableDynamicConfigForNode(client clientset.Interface, nodeName string, kubeletVersion *version.Version) error

EnableDynamicConfigForNode updates the Node's ConfigSource to enable Dynamic Kubelet Configuration, depending on what version the kubelet is Used at "kubeadm init", "kubeadm join" and "kubeadm upgrade" time This func is ONLY run if the user enables the `DynamicKubeletConfig` feature gate, which is by default off

func GetLocalNodeTLSBootstrappedClient

func GetLocalNodeTLSBootstrappedClient() (clientset.Interface, error)

GetLocalNodeTLSBootstrappedClient waits for the kubelet to perform the TLS bootstrap and then creates a client from config file /etc/kubernetes/kubelet.conf

func WriteConfigToDisk

func WriteConfigToDisk(kubeletConfig *kubeletconfigv1beta1.KubeletConfiguration) error

WriteConfigToDisk writes the kubelet config object down to a file Used at "kubeadm init" and "kubeadm upgrade" time

func WriteKubeletDynamicEnvFile

func WriteKubeletDynamicEnvFile(nodeRegOpts *kubeadmapi.NodeRegistrationOptions, registerTaintsUsingFlags bool) error

WriteKubeletDynamicEnvFile writes a environment file with dynamic flags to the kubelet. Used at "kubeadm init" and "kubeadm join" time.
