Functions

func ConfigGlobalScopeDefaultNetworks

func ConfigGlobalScopeDefaultNetworks(defaultAddressPool []*NetworkToSplit) error

ConfigGlobalScopeDefaultNetworks configures global default pool. Ideally this will be called from SwarmKit as part of swarm init

func GetGlobalScopeDefaultNetworks

func GetGlobalScopeDefaultNetworks() []*net.IPNet

GetGlobalScopeDefaultNetworks returns a copy of the global-sopce network list.

func GetLocalScopeDefaultNetworks

func GetLocalScopeDefaultNetworks() []*net.IPNet

GetLocalScopeDefaultNetworks returns a copy of the default local-scope network list.

func SplitNetworks

func SplitNetworks(list []*NetworkToSplit) ([]*net.IPNet, error)

SplitNetworks takes a slice of networks, split them accordingly and returns them

Types

type NetworkToSplit

type NetworkToSplit struct {
	Base string `json:"base"`
	Size int    `json:"size"`
}

NetworkToSplit represent a network that has to be split in chunks with mask length Size. Each subnet in the set is derived from the Base pool. Base is to be passed in CIDR format. Example: a Base "10.10.0.0/16 with Size 24 will define the set of 256 10.10.[0-255].0/24 address pools
