Functions

func BootstrapKubeletConfigController

func BootstrapKubeletConfigController(defaultConfig *kubeletconfiginternal.KubeletConfiguration,
	initConfigDirFlag flag.StringFlag,
	dynamicConfigDirFlag flag.StringFlag) (*kubeletconfiginternal.KubeletConfiguration, *kubeletconfig.Controller, error)

BootstrapKubeletConfigController constructs and bootstrap a configuration controller

func BuildAuth

func BuildAuth(nodeName types.NodeName, client clientset.Interface, config kubeletconfig.KubeletConfiguration) (server.AuthInterface, error)

BuildAuth creates an authenticator, an authorizer, and a matching authorizer attributes getter compatible with the kubelet's needs

func BuildAuthn

func BuildAuthn(client authenticationclient.TokenReviewInterface, authn kubeletconfig.KubeletAuthentication) (authenticator.Request, error)

BuildAuthn creates an authenticator compatible with the kubelet's needs

func BuildAuthz

func BuildAuthz(client authorizationclient.SubjectAccessReviewInterface, authz kubeletconfig.KubeletAuthorization) (authorizer.Authorizer, error)

BuildAuthz creates an authorizer compatible with the kubelet's needs

func CreateAPIServerClientConfig

func CreateAPIServerClientConfig(s *options.KubeletServer) (*restclient.Config, error)

CreateAPIServerClientConfig generates a client.Config from command line flags via createClientConfig and then injects chaos into the configuration via addChaosToClientConfig. This func is exported to support integration with third party kubelet extensions (e.g. kubernetes-mesos).

func CreateAndInitKubelet

func CreateAndInitKubelet(kubeCfg *kubeletconfiginternal.KubeletConfiguration,
	kubeDeps *kubelet.Dependencies,
	crOptions *config.ContainerRuntimeOptions,
	containerRuntime string,
	runtimeCgroups string,
	hostnameOverride string,
	nodeIP string,
	providerID string,
	cloudProvider string,
	certDirectory string,
	rootDirectory string,
	registerNode bool,
	registerWithTaints []api.Taint,
	allowedUnsafeSysctls []string,
	containerized bool,
	remoteRuntimeEndpoint string,
	remoteImageEndpoint string,
	experimentalMounterPath string,
	experimentalKernelMemcgNotification bool,
	experimentalCheckNodeCapabilitiesBeforeMount bool,
	experimentalNodeAllocatableIgnoreEvictionThreshold bool,
	minimumGCAge metav1.Duration,
	maxPerPodContainerCount int32,
	maxContainerCount int32,
	masterServiceNamespace string,
	registerSchedulable bool,
	nonMasqueradeCIDR string,
	keepTerminatedPodVolumes bool,
	nodeLabels map[string]string,
	seccompProfileRoot string,
	bootstrapCheckpointPath string) (k kubelet.Bootstrap, err error)

func GetDynamicPluginProber

func GetDynamicPluginProber(pluginDir string) volume.DynamicPluginProber

GetDynamicPluginProber gets the probers of dynamically discoverable plugins for kubelet. Currently only Flexvolume plugins are dynamically discoverable.

func InitializeTLS

func InitializeTLS(kf *options.KubeletFlags, kc *kubeletconfiginternal.KubeletConfiguration) (*server.TLSOptions, error)

InitializeTLS checks for a configured TLSCertFile and TLSPrivateKeyFile: if unspecified a new self-signed certificate and key file are generated. Returns a configured server.TLSOptions object.

func NewKubeletCommand

func NewKubeletCommand() *cobra.Command

NewKubeletCommand creates a *cobra.Command object with default parameters

func ProbeNetworkPlugins

func ProbeNetworkPlugins(cniConfDir, cniBinDir string) []network.NetworkPlugin

ProbeNetworkPlugins collects all compiled-in plugins

func ProbeVolumePlugins

func ProbeVolumePlugins() []volume.VolumePlugin

ProbeVolumePlugins collects all volume plugins into an easy to use list.

func Run

func Run(s *options.KubeletServer, kubeDeps *kubelet.Dependencies) error

Run runs the specified KubeletServer with the given Dependencies. This should never exit. The kubeDeps argument may be nil - if so, it is initialized from the settings on KubeletServer. Otherwise, the caller is assumed to have set up the Dependencies object and a default one will not be generated.

func RunDockershim

func RunDockershim(f *options.KubeletFlags, c *kubeletconfiginternal.KubeletConfiguration) error

RunDockershim only starts the dockershim in current process. This is only used for cri validate testing purpose TODO(random-liu): Move this to a separate binary.

func RunKubelet

func RunKubelet(kubeFlags *options.KubeletFlags, kubeCfg *kubeletconfiginternal.KubeletConfiguration, kubeDeps *kubelet.Dependencies, runOnce bool) error

RunKubelet is responsible for setting up and running a kubelet. It is used in three different applications:

1 Integration tests
2 Kubelet binary
3 Standalone 'kubernetes' binary

Eventually, #2 will be replaced with instances of #3

func UnsecuredDependencies

func UnsecuredDependencies(s *options.KubeletServer) (*kubelet.Dependencies, error)

UnsecuredDependencies returns a Dependencies suitable for being run, or an error if the server setup is not valid. It will not start any background processes, and does not include authentication/authorization
