	// contains filtered or unexported fields
}

func (d *DNS) Update() (error, bool)

type EgressDNS

type EgressDNS struct {

	// Report changes when there are dns updates
	Updates chan EgressDNSUpdate
	// contains filtered or unexported fields
}

func NewEgressDNS

func NewEgressDNS() *EgressDNS

func (*EgressDNS) Add

func (e *EgressDNS) Add(policy networkapi.EgressNetworkPolicy)

func (*EgressDNS) Delete

func (e *EgressDNS) Delete(policy networkapi.EgressNetworkPolicy)

func (*EgressDNS) GetIPs

func (e *EgressDNS) GetIPs(policy networkapi.EgressNetworkPolicy, dnsName string) []net.IP

func (*EgressDNS) GetMinQueryTime

func (e *EgressDNS) GetMinQueryTime() (time.Time, ktypes.UID, string, bool)

func (*EgressDNS) GetNetCIDRs

func (e *EgressDNS) GetNetCIDRs(policy networkapi.EgressNetworkPolicy, dnsName string) []net.IPNet

func (*EgressDNS) Sync

func (e *EgressDNS) Sync()

func (*EgressDNS) Update

func (e *EgressDNS) Update(policyUID ktypes.UID) (error, bool)

type EgressDNSUpdate

type EgressDNSUpdate struct {
	UID       ktypes.UID
	Namespace string
}

type EgressIPTracker

type EgressIPTracker struct {
	sync.Mutex
	// contains filtered or unexported fields
}

func NewEgressIPTracker

func NewEgressIPTracker(watcher EgressIPWatcher) *EgressIPTracker

func (*EgressIPTracker) DeleteNetNamespaceEgress

func (eit *EgressIPTracker) DeleteNetNamespaceEgress(vnid uint32)

func (*EgressIPTracker) Ping

func (eit *EgressIPTracker) Ping(ip string, timeout time.Duration) bool

Ping a node and return whether or not it is online. We do this by trying to open a TCP connection to the "discard" service (port 9); if the node is offline, the attempt will time out with no response (and we will return false). If the node is online then we presumably will get a "connection refused" error; the code below assumes that anything other than timing out indicates that the node is online.

func (*EgressIPTracker) ReallocateEgressIPs

ReallocateEgressIPs returns a map from Node name to array-of-Egress-IP. Unchanged nodes are not included.
