Functions

func CLIFlags

func CLIFlags(kubernetesVersion *semver.Version, criName extensionsv1alpha1.CRIName, image *imagevector.Image, cliFlags components.ConfigurableKubeletCLIFlags) []string

CLIFlags returns a list of kubelet CLI flags based on the provided parameters and for the provided Kubernetes version.

func Config

func Config(kubernetesVersion *semver.Version, clusterDNSAddress, clusterDomain string, params components.ConfigurableKubeletConfigParameters) *kubeletconfigv1beta1.KubeletConfiguration

Config returns a kubelet config based on the provided parameters and for the provided Kubernetes version.

func New

func New() *component

New returns a new kubelet component.

func ShouldProtectKernelDefaultsBeEnabled

func ShouldProtectKernelDefaultsBeEnabled(kubeletConfigParameters *components.ConfigurableKubeletConfigParameters, kubernetesVersion *semver.Version) bool

ShouldProtectKernelDefaultsBeEnabled returns true if ProtectKernelDefaults is set to true in the kubelet's config parameters or k8s version is >= 1.26.

Types

type ConfigCodec

type ConfigCodec interface {
	// Encode encodes the given *kubeletconfigv1beta1.KubeletConfiguration into a *extensionsv1alpha1.FileContentInline.
	Encode(*kubeletconfigv1beta1.KubeletConfiguration, string) (*extensionsv1alpha1.FileContentInline, error)
	// Decode decodes a *kubeletconfigv1beta1.KubeletConfiguration from the given *extensionsv1alpha1.FileContentInline.
	Decode(*extensionsv1alpha1.FileContentInline) (*kubeletconfigv1beta1.KubeletConfiguration, error)
}

ConfigCodec contains methods for encoding and decoding *kubeletconfigv1beta1.KubeletConfiguration objects to and from *extensionsv1alpha1.FileContentInline.

func NewConfigCodec

func NewConfigCodec(fciCodec oscutils.FileContentInlineCodec) ConfigCodec

NewConfigCodec creates an returns a new ConfigCodec.
