Types

type AuthData

type AuthData struct {
	// contains filtered or unexported fields
}

AuthData contains the information exchanged with the discovery methods on how to contact a remote Authentication Service.

func NewAuthData

func NewAuthData(address string, port int, ttl uint32) *AuthData

NewAuthData creates a new AuthData struct.

func (*AuthData) Get

func (authData *AuthData) Get(discovery *Controller, entry *zeroconf.ServiceEntry) error

Get decodes and populates the AuthData struct given a discovery Controller and a DNS entry.

func (*AuthData) IsComplete

func (authData *AuthData) IsComplete() bool

IsComplete checks if both address and port are correctly set.

type Controller

type Controller struct {
	client.Client

	LocalCluster discoveryv1alpha1.ClusterIdentity
	// contains filtered or unexported fields
}

Controller is the controller for the discovery functionalities.

func NewDiscoveryCtrl

func NewDiscoveryCtrl(cl, namespacedClient client.Client, namespace string,
	localCluster discoveryv1alpha1.ClusterIdentity, config MDNSConfig, dialTCPTimeout time.Duration) *Controller

NewDiscoveryCtrl returns a new discovery controller.

func (*Controller) Start

func (discovery *Controller) Start(ctx context.Context) error

Start starts the discovery logic.

type MDNSConfig

type MDNSConfig struct {
	EnableAdvertisement bool
	EnableDiscovery     bool

	Service string
	Domain  string
	TTL     time.Duration

	ResolveRefreshTime time.Duration
}

MDNSConfig defines the configuration parameters for the mDNS service.
