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`

func FromEnv

func FromEnv() (*Opts, error)

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

func New

func New() *Opts
