AcceptedCiphers is the list of accepted TLS ciphers, with known weak ciphers elided Note this list should be a moving target.


func AvailableTraceExporters

func AvailableTraceExporters() []string

AvailableTraceExporters gets the list of registered exporters

func GetTracingExporter

func GetTracingExporter(name string, opts TracingExporterOptions) (trace.Exporter, error)

GetTracingExporter gets the specified tracing exporter passing in the options to the exporter init function. For an exporter to be availbale here it must be registered with `RegisterTracingExporter`.

func NewCommand

func NewCommand(ctx context.Context, name string, c Opts) *cobra.Command

NewCommand creates a new top-level command. This command is used to start the virtual-kubelet daemon

func NewJaegerExporter

func NewJaegerExporter(opts TracingExporterOptions) (trace.Exporter, error)

NewJaegerExporter creates a new opencensus tracing exporter.

func NewOCAgentExporter

func NewOCAgentExporter(opts TracingExporterOptions) (trace.Exporter, error)

NewOCAgentExporter creates a new opencensus tracing exporter using the opencensus agent forwarder.

func NodeFromProvider

func NodeFromProvider(ctx context.Context, name string, taint *v1.Taint, p providers.Provider) *v1.Node

NodeFromProvider builds a kubernetes node object from a provider This is a temporary solution until node stuff actually split off from the provider interface itself.

func RegisterTracingExporter

func RegisterTracingExporter(name string, f TracingExporterInitFunc)

RegisterTracingExporter registers a tracing exporter. For a user to select an exporter, it must be registered here.

func SetDefaultOpts

func SetDefaultOpts(c *Opts) error

SetDefaultOpts sets default options for unset values on the passed in option struct. Fields tht are already set will not be modified.


type Opts

type Opts struct {
	// Path to the kubeconfig to use to connect to the Kubernetes API server.
	KubeConfigPath string
	// Namespace to watch for pods and other resources
	KubeNamespace string
	// Sets the port to listen for requests from the Kubernetes API server
	ListenPort int32

	// Node name to use when creating a node in Kubernetes
	NodeName string

	// Operating system to run pods for
	OperatingSystem string

	Provider           string
	ProviderConfigPath string

	TaintKey     string
	TaintEffect  string
	DisableTaint bool

	MetricsAddr string

	// Number of workers to use to handle pod notifications
	PodSyncWorkers       int
	InformerResyncPeriod time.Duration

	// Use node leases when supported by Kubernetes (instead of node status updates)
	EnableNodeLease bool

	TraceExporters  []string
	TraceSampleRate string
	TraceConfig     TracingExporterOptions

	// Startup Timeout is how long to wait for the kubelet to start
	StartupTimeout time.Duration

Opts stores all the options for configuring the root virtual-kubelet command. It is used for setting flag values.

You can set the default options by creating a new `Opts` struct and passing it into `SetDefaultOpts`

type TracingExporterInitFunc

type TracingExporterInitFunc func(TracingExporterOptions) (trace.Exporter, error)

TracingExporterInitFunc is the function that is called to initialize an exporter. This is used when registering an exporter and called when a user specifed they want to use the exporter.

type TracingExporterOptions

type TracingExporterOptions struct {
	Tags        map[string]string
	ServiceName string
