Functions

func Execute

func Execute(cmd *cobra.Command)

func InitGlobalFlags

func InitGlobalFlags(cmd *cobra.Command, vp *viper.Viper)

func NewOperatorCmd

func NewOperatorCmd(h *hive.Hive) *cobra.Command

Types

type LeaderLifecycle

type LeaderLifecycle struct {
	cell.DefaultLifecycle
}

LeaderLifecycle is the inner lifecycle of the operator that is started when this operator instance is elected leader. It implements cell.Lifecycle allowing cells to use it.

type ProviderFlagsHooks

type ProviderFlagsHooks interface {
	RegisterProviderFlag(cmd *cobra.Command, vp *viper.Viper)
}
