Functions

func ProbeVolumePlugins

func ProbeVolumePlugins() []volume.Plugin

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

func RunKubelet added in v0.12.0

func RunKubelet(kcfg *KubeletConfig)

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 SimpleRunKubelet added in v0.12.0

func SimpleRunKubelet(client *client.Client,
	dockerClient dockertools.DockerInterface,
	hostname, rootDir, manifestURL, address string,
	port uint,
	masterServiceNamespace string,
	volumePlugins []volume.Plugin,
	tlsOptions *kubelet.TLSOptions,
	cadvisorInterface cadvisor.Interface)

SimpleRunKubelet is a simple way to start a Kubelet talking to dockerEndpoint, using an API Client. Under the hood it calls RunKubelet (below)

Types

type KubeletConfig struct {
	KubeClient                     *client.Client
	DockerClient                   dockertools.DockerInterface
	CadvisorInterface              cadvisor.Interface
	Address                        util.IP
	AllowPrivileged                bool

	EnableDebuggingHandlers        bool
	Port                           uint
	Runonce                        bool
	MasterServiceNamespace         string

	TLSOptions                     *kubelet.TLSOptions
}

KubeletConfig is all of the parameters necessary for running a kubelet. TODO: This should probably be merged with KubeletServer. The extra object is a consequence of refactoring.

	StatusUpdateFrequency          time.Duration
	ManifestURL                    string
	EnableServer                   bool

	MaxContainerCount              int
	AuthPath                       string
	CadvisorPort                   uint
	OOMScoreAdj                    int
	APIServerList                  util.StringList

KubeletServer encapsulates all of the parameters necessary for starting up a kubelet. These can either be set via command line or directly.

func NewKubeletServer added in v0.12.0

func NewKubeletServer() *KubeletServer

NewKubeletServer will create a new KubeletServer with default values.

func (*KubeletServer) AddFlags added in v0.12.0

func (s *KubeletServer) AddFlags(fs *pflag.FlagSet)

AddFlags adds flags for a specific KubeletServer to the specified FlagSet

func (*KubeletServer) Run added in v0.12.0

func (s *KubeletServer) Run(_ []string) error

Run runs the specified KubeletServer. This should never exit.
