Weel-known errors returned by IPAM

Types

type Callback

type Callback interface {
	// RegisterDriver provides a way for Remote drivers to dynamically register new NetworkType and associate with a ipam instance
	RegisterIpamDriver(name string, driver Ipam) error
}

Callback provides a Callback interface for registering an IPAM instance into LibNetwork

type Ipam

type Ipam interface {
	// GetDefaultAddressSpaces returns the default local and global address spaces for this ipam
	GetDefaultAddressSpaces() (string, string, error)
	// RequestPool returns an address pool along with its unique id. Address space is a mandatory field
	// which denotes a set of non-overlapping pools. pool describes the pool of addresses in CIDR notation.
	// subpool indicates a smaller range of addresses from the pool, for now it is specified in CIDR notation.
	// Both pool and subpool are non mandatory fields. When they are not specified, Ipam driver may choose to
	// return a self chosen pool for this request. In such case the v6 flag needs to be set appropriately so
	// that the driver would return the expected ip version pool.
	RequestPool(addressSpace, pool, subPool string, options map[string]string, v6 bool) (string, *net.IPNet, map[string]string, error)
	// ReleasePool releases the address pool identified by the passed id
	ReleasePool(poolID string) error
	// Request address from the specified pool ID. Input options or preferred IP can be passed.
	RequestAddress(string, net.IP, map[string]string) (*net.IPNet, map[string]string, error)
	// Release the address from the specified pool ID
	ReleaseAddress(string, net.IP) error
}

Ipam represents the interface the IPAM service plugins must implement in order to allow injection/modification of IPAM database.
