Types

type AllocatedRange

type AllocatedRange struct {
	StartIP net.IP
	EndIP   net.IP
}

AllocatedRange contains range of IPs allocated for the node

type AllocationConfig

type AllocationConfig struct {
	PoolName         string
	Subnet           *net.IPNet
	Gateway          net.IP
	PerNodeBlockSize int
	NodeSelector     *corev1.NodeSelector
}

AllocationConfig contains configuration of the IP pool

func (*AllocationConfig) Equal

func (pc *AllocationConfig) Equal(other *AllocationConfig) bool

type PoolAllocator

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

PoolAllocator contains pool settings and related allocations

func CreatePoolAllocatorFromIPPool

func CreatePoolAllocatorFromIPPool(ctx context.Context,
	p *ipamv1alpha1.IPPool, nodes sets.Set[string]) *PoolAllocator

CreatePoolAllocatorFromIPPool creates a PoolAllocator and load data from the IPPool CR the nodes Set contains the nodes that match the current NodeSelector of the IPPool it is used to filter out Allocations that are not relevant anymore

func (*PoolAllocator) AllocateFromPool

func (pa *PoolAllocator) AllocateFromPool(ctx context.Context, node string) (*AllocatedRange, error)

AllocateFromPool allocates a new range in the poolAllocator or return existing one, returns ErrNoFreeRanges if no free ranges available

func (*PoolAllocator) Deallocate

func (pa *PoolAllocator) Deallocate(ctx context.Context, node string)

Deallocate remove info about allocation for the node from the poolAllocator
