Functions

func InstallFlags

func InstallFlags(flags *pflag.FlagSet, o *Opts)

InstallFlags configures the virtual kubelet flags.

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.

	MetricsAddress             string

	HomeAPIServerHost string
	HomeAPIServerPort string
}

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

func NewOpts

func NewOpts() *Opts

NewOpts returns an Opts struct with the default values set.
