Functions

func CreateConfigMap

func CreateConfigMap(cfg *kubeadmapi.ClusterConfiguration, 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(client clientset.Interface, kubeletVersion *version.Version, kubeletDir string) 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

func GetNodeNameAndHostname

func GetNodeNameAndHostname(cfg *kubeadmapi.NodeRegistrationOptions) (string, string, error)

GetNodeNameAndHostname obtains the name for this Node using the following precedence (from lower to higher): - actual hostname - NodeRegistrationOptions.Name (same as "--node-name" passed to "kubeadm init/join") - "hostname-overide" flag in NodeRegistrationOptions.KubeletExtraArgs It also returns the hostname or an error if getting the hostname failed.

func TryRestartKubelet

func TryRestartKubelet()

TryRestartKubelet attempts to restart the kubelet service

func TryStartKubelet

func TryStartKubelet()

TryStartKubelet attempts to bring up kubelet service

func TryStopKubelet

func TryStopKubelet()

TryStopKubelet attempts to bring down the kubelet service momentarily

func WriteConfigToDisk

func WriteConfigToDisk(kubeletCfg kubeadmapi.ComponentConfig, kubeletDir string) error

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

func WriteKubeletDynamicEnvFile

func WriteKubeletDynamicEnvFile(cfg *kubeadmapi.ClusterConfiguration, nodeReg *kubeadmapi.NodeRegistrationOptions, registerTaintsUsingFlags bool, kubeletDir string) error

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