Types ¶

type AddressRange ¶

type AddressRange struct {
	Sub        *net.IPNet
	Start, End uint64
}

AddressRange specifies first and last ip ordinal which identify a range in a a pool of addresses

func (*AddressRange) MarshalJSON ¶

func (r *AddressRange) MarshalJSON() ([]byte, error)

MarshalJSON returns the JSON encoding of the Range object

func (*AddressRange) String ¶

func (r *AddressRange) String() string

String returns the string form of the AddressRange object

func (*AddressRange) UnmarshalJSON ¶

func (r *AddressRange) UnmarshalJSON(data []byte) error

UnmarshalJSON decodes data into the Range object

type Allocator ¶

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

Allocator provides per address space ipv4/ipv6 book keeping

func NewAllocator ¶

func NewAllocator(lcDs, glDs datastore.DataStore) (*Allocator, error)

NewAllocator returns an instance of libnetwork ipam

func (*Allocator) DumpDatabase ¶

func (a *Allocator) DumpDatabase() string

DumpDatabase dumps the internal info

func (*Allocator) GetDefaultAddressSpaces ¶

func (a *Allocator) GetDefaultAddressSpaces() (string, string, error)

GetDefaultAddressSpaces returns the local and global default address spaces

func (*Allocator) ReleaseAddress ¶

func (a *Allocator) ReleaseAddress(poolID string, address net.IP) error

ReleaseAddress releases the address from the specified pool ID

func (*Allocator) ReleasePool ¶

func (a *Allocator) ReleasePool(poolID string) error

ReleasePool releases the address pool identified by the passed id

func (*Allocator) RequestAddress ¶
