func ListenAndServeKubeletReadOnlyServer(host HostInterface, resourceAnalyzer stats.ResourceAnalyzer, address net.IP, port uint)

ListenAndServeKubeletReadOnlyServer initializes a server to respond to HTTP network requests on the Kubelet.

func ListenAndServeKubeletServer

func ListenAndServeKubeletServer(
	host HostInterface,
	resourceAnalyzer stats.ResourceAnalyzer,
	address net.IP,
	port uint,
	tlsOptions *TLSOptions,
	auth AuthInterface,
	enableDebuggingHandlers,
	enableContentionProfiling,
	redirectContainerStreaming bool,
	criHandler http.Handler)

func NewNodeAuthorizerAttributesGetter

func NewNodeAuthorizerAttributesGetter(nodeName types.NodeName) authorizer.RequestAttributesGetter

Types

type AuthInterface

AuthInterface contains all methods required by the auth filters

func NewKubeletAuth

func NewKubeletAuth(authenticator authenticator.Request, authorizerAttributeGetter authorizer.RequestAttributesGetter, authorizer authorizer.Authorizer) AuthInterface

NewKubeletAuth returns a kubelet.AuthInterface composed of the given authenticator, attribute getter, and authorizer

type HostInterface

type HostInterface interface {
	stats.StatsProvider
	GetVersionInfo() (*cadvisorapi.VersionInfo, error)
	GetCachedMachineInfo() (*cadvisorapi.MachineInfo, error)
	GetRunningPods() ([]*v1.Pod, error)
	RunInContainer(name string, uid types.UID, container string, cmd []string) ([]byte, error)
	GetKubeletContainerLogs(ctx context.Context, podFullName, containerName string, logOptions *v1.PodLogOptions, stdout, stderr io.Writer) error
	ServeLogs(w http.ResponseWriter, req *http.Request)
	ResyncInterval() time.Duration
	GetHostname() string
	LatestLoopEntryTime() time.Time
	GetExec(podFullName string, podUID types.UID, containerName string, cmd []string, streamOpts remotecommandserver.Options) (*url.URL, error)
	GetAttach(podFullName string, podUID types.UID, containerName string, streamOpts remotecommandserver.Options) (*url.URL, error)
	GetPortForward(podName, podNamespace string, podUID types.UID, portForwardOpts portforward.V4Options) (*url.URL, error)
}

HostInterface contains all the kubelet methods required by the server. For testability.

type KubeletAuth

type KubeletAuth struct {
	// authenticator identifies the user for requests to the Kubelet API
	authenticator.Request
	// authorizerAttributeGetter builds authorization.Attributes for a request to the Kubelet API
	authorizer.RequestAttributesGetter
	// authorizer determines whether a given authorization.Attributes is allowed
	authorizer.Authorizer
}

KubeletAuth implements AuthInterface

type Server

type Server struct {
	// contains filtered or unexported fields
}

Server is a http.Handler which exposes kubelet functionality over HTTP.

func NewServer

func NewServer(
	host HostInterface,
	resourceAnalyzer stats.ResourceAnalyzer,
	auth AuthInterface,
	enableDebuggingHandlers,
	enableContentionProfiling,
	redirectContainerStreaming bool,
	criHandler http.Handler) Server

NewServer initializes and configures a kubelet.Server object to handle HTTP requests.

func (*Server) InstallAuthFilter

func (s *Server) InstallAuthFilter()

InstallAuthFilter installs authentication filters with the restful Container.

func (*Server) InstallDebuggingDisabledHandlers

func (s *Server) InstallDebuggingDisabledHandlers()

InstallDebuggingDisabledHandlers registers the HTTP request patterns that provide better error message

func (*Server) InstallDebuggingHandlers

func (s *Server) InstallDebuggingHandlers(criHandler http.Handler)

InstallDebuggingHandlers registers the HTTP request patterns that serve logs or run commands/containers

func (*Server) InstallDefaultHandlers

func (s *Server) InstallDefaultHandlers()

InstallDefaultHandlers registers the default set of supported HTTP request patterns with the restful Container.

func (*Server) ServeHTTP

func (s *Server) ServeHTTP(w http.ResponseWriter, req *http.Request)

ServeHTTP responds to HTTP requests on the Kubelet.

type TLSOptions
