Functions

func ApplyKubeProxyRBAC

func ApplyKubeProxyRBAC(client *clientset.Clientset, ctx context.Context) error

func NewAPIServerStaticPod

func NewAPIServerStaticPod(cfg *config.ControlPlaneConfiguration) (*corev1.Pod, error)

func NewBootstrapServerStaticPod

func NewBootstrapServerStaticPod(cfg *config.ControlPlaneConfiguration) *corev1.Pod

func NewControllerManagerStaticPod

func NewControllerManagerStaticPod(cfg *config.ControlPlaneConfiguration) *corev1.Pod

func NewKubeProxyConfigMap

func NewKubeProxyConfigMap(cfg *config.ControlPlaneConfiguration) (*corev1.ConfigMap, error)

func NewSchedulerStaticPod

func NewSchedulerStaticPod(cfg *config.ControlPlaneConfiguration) *corev1.Pod

func WriteKubeletConfigFile

func WriteKubeletConfigFile(kc *kubeletconfigv1beta1.KubeletConfiguration, path string) error

func WriteKubeletDynamicEnvFile

func WriteKubeletDynamicEnvFile(cfg *config.NodeConfiguration, registerTaintsUsingFlags bool, kubeletDir string) error

WriteKubeletDynamicEnvFile writes an environment file with dynamic flags to the kubelet. This is identical to how kubeadm creates a dynamic environment file, but with names changed. This will most likely be changed in the future to fit better with crit usage.
