Functions

func DriverNames

func DriverNames() []string

DriverNames returns the list of registered platform driver implementation names.

func FindFreeNetwork

func FindFreeNetwork(pool NetworkPool, existingNetworks *networkapi.NetworkList) (*net.IPNet, error)

FindFreeNetwork finds a free network in the pool.

func NetworksIntersect

func NetworksIntersect(a, b net.IPNet) bool

NetworksIntersect returns whether two networks have any common IP addresses.

func NewNetworkV1alpha1ServiceIterator

func NewNetworkV1alpha1ServiceIterator(ctx context.Context) (networkv1alpha1.NetworkService, error)

NewNetworkV1alpha1ServiceIterator returns a networkv1alpha1.NetworkService-compatible implementation which iterates over each supported network driver and calls the representing method. This is useful in circumstances where the driver is not supplied. The first network driver to succeed is returned in all circumstances.

func Strategies

func Strategies() map[string]*Strategy

Strategies returns the list of registered platform implementations.

Types

type NetworkPool

type NetworkPool []NetworkPoolEntry

type NetworkPoolEntry

type NetworkPoolEntry struct {
	// Subnet is the CIDR notation of the network to be sub-divided.
	Subnet string
	// Size is the size of the subnets to be allocated, in bits.
	Size int
}

NetworkPoolEntry describes a network to be used for allocating IP ranges.

type NewStrategyConstructor

type NewStrategyConstructor[T any] func(context.Context, ...any) (T, error)

NewStrategyConstructor is a prototype for the instantiation function of a platform driver implementation.

type Strategy

type Strategy struct {
	Name               string
	NewNetworkV1alpha1 NewStrategyConstructor[networkv1alpha1.NetworkService]
}

Strategy represents canonical reference of a machine driver and their platform.
