Configuration is the controller conf

func ParseFlags

func ParseFlags() (*Configuration, error)

ParseFlags parses cmd args then init kubeclient and conf TODO: validate configuration

type Controller

type Controller struct {
	OVNNbClient ovs.NbClient
	OVNSbClient ovs.SbClient

	// ExternalGatewayType define external gateway type, centralized
	ExternalGatewayType string

	UpdateSwitchLBRuleQueue workqueue.RateLimitingInterface
	// contains filtered or unexported fields
}

Controller is kube-ovn main controller that watch ns/pod/node/svc/ep and operate ovn
