Types

type AddressFamily

type AddressFamily string

const (
	IPv4Family AddressFamily = "IPv4"
	IPv6Family AddressFamily = "IPv6"
)

type LBIPAM

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

LBIPAM is the loadbalancer IP address manager, controller which allocates and assigns IP addresses to LoadBalancer services from the configured set of LoadBalancerIPPools in the cluster.

func (*LBIPAM) RegisterOnReady

func (ipam *LBIPAM) RegisterOnReady(cb func())

RegisterOnReady registers a callback function which will be invoked when LBIPAM is done initializing. Note: mainly used in the integration tests.

func (*LBIPAM) Run

func (ipam *LBIPAM) Run(ctx context.Context, health cell.HealthReporter)

type LBRange

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

func NewLBRange

func NewLBRange(from, to netip.Addr, pool *cilium_api_v2alpha1.CiliumLoadBalancerIPPool) (*LBRange, error)

func (*LBRange) Disabled

func (lr *LBRange) Disabled() bool

func (*LBRange) Equal

func (lr *LBRange) Equal(other *LBRange) bool

func (*LBRange) EqualCIDR

func (lr *LBRange) EqualCIDR(from, to netip.Addr) bool

func (*LBRange) String

func (lr *LBRange) String() string

type ServiceView

type ServiceView struct {
	Key    resource.Key
	Labels slim_labels.Set

	Generation int64
	Status     *slim_core_v1.ServiceStatus

	SharingKey string
	// These required to determine if a service conflicts with another for sharing an ip
	ExternalTrafficPolicy slim_core_v1.ServiceExternalTrafficPolicy
	Ports                 []slim_core_v1.ServicePort
	Namespace             string
	Selector              map[string]string

	// The specific IPs requested by the service
	RequestedIPs []netip.Addr
	// The IP families requested by the service
	RequestedFamilies struct {
		IPv4 bool
		IPv6 bool
	}
	// The IPs we have allocated for this IP
	AllocatedIPs []ServiceViewIP
}

ServiceView is the LB IPAM's view of the service, the minimal amount of info we need about it.

type ServiceViewIP

type ServiceViewIP struct {
	IP     netip.Addr
	Origin *LBRange
}

ServiceViewIP is the IP and from which range it was allocated
