Variables

var DefaultReflectorsTypes = map[resources.ResourceReflected]vkv1alpha1.ReflectionType{
	resources.Pod:                   vkv1alpha1.CustomLiqo,
	resources.Service:               vkv1alpha1.DenyList,
	resources.Ingress:               vkv1alpha1.DenyList,

	resources.PersistentVolumeClaim: vkv1alpha1.CustomLiqo,
	resources.Event:                 vkv1alpha1.DenyList,
}

DefaultReflectorsTypes contains the default type of reflection for each reflected resource.

var DefaultReflectorsWorkers = map[resources.ResourceReflected]uint{
	resources.Pod:                   10,
	resources.Service:               3,
	resources.EndpointSlice:         10,
	resources.Ingress:               3,
	resources.ConfigMap:             3,
	resources.Secret:                3,
	resources.ServiceAccount:        3,
	resources.PersistentVolumeClaim: 3,
	resources.Event:                 3,
}

DefaultReflectorsWorkers contains the default number of workers for each reflected resource.

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.

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.
