Functions

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 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 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.

Types

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     opencensus.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`
