var ErrNoFreePort = errors.New("no free port find")

ErrNoFreePort is returned when trying to reserve a port but all the the port of the range have been already reserved

Types

type Allocator

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

Allocator implements the PortAllocator interface

func NewAllocator

func NewAllocator(pRange PortRange, store backend.Store) *Allocator

NewAllocator return a PortAllocator

func (*Allocator) Release

func (a *Allocator) Release(ns string, port int) error

Release implements PortAllocator interface

func (*Allocator) Reserve

func (a *Allocator) Reserve(ns string) (int, error)

Reserve implements PortAllocator interface

type PortAllocator

type PortAllocator interface {
	Reserve(ns string) (int, error)
	Release(ns string, port int) error
}

PortAllocator is the interface that defines the behavior to reserve a port in a specific network namespace

type PortRange

type PortRange struct {
	Start int
	End   int
}

PortRange hold the beginging and end of a range of port a PortAllocator can reserve
