Functions

func Finalize added in v1.5.0 

func Finalize(ctx context.Context) error

TODO: figure out why the Init calls are wrapped in once.Do - implies it can be called multiple times, but once Finalize is called things will not be functional.

func Init 

func Init(ctx context.Context, sess *session.Session, source extraconfig.DataSource, sink extraconfig.DataSink) error

func ScopedAliasName 

func ScopedAliasName(scope string, container string, alias string) string

ScopedAliasName returns the fully qualified name of an alias, scoped to the scope and optionally a container

Types

type AddContainerOptions

An AddressSpace is a collection of IP address ranges

func NewAddressSpaceFromNetwork 

func NewAddressSpaceFromNetwork(ipRange *net.IPNet) *AddressSpace

NewAddressSpaceFromNetwork creates a new AddressSpace from a network specification.

func NewAddressSpaceFromRange 

func NewAddressSpaceFromRange(firstIP net.IP, lastIP net.IP) *AddressSpace

NewAddressSpaceFromRange creates a new AddressSpace from a range of IP addresses.

func (*AddressSpace) Defragment

func (*AddressSpace) ReleaseIP4 

func (s *AddressSpace) ReleaseIP4(ip net.IP) error

ReleaseIP4 releases the given IPv4 address.

func (*AddressSpace) ReleaseIP4Range 

func (s *AddressSpace) ReleaseIP4Range(space *AddressSpace) error

ReleaseIP4Range releases a sub address space into the parent address space. Sub address space has to have only a single available range.

func (*AddressSpace) ReserveIP4Range 

func (s *AddressSpace) ReserveIP4Range(firstIP net.IP, lastIP net.IP) (*AddressSpace, error)

func (s *AddressSpace) ReserveNextIP4() (net.IP, error)

ReserveNextIP4 reserves the next available IPv4 address.

func (*AddressSpace) ReserveNextIP4Net 

func (s *AddressSpace) ReserveNextIP4Net(mask net.IPMask) (*AddressSpace, error)

ReserveNextIP4Net reserves a new sub address space within the given address space, given a bitmask specifying the "width" of the requested space.
