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 ConfigLocalScopeDefaultNetworks

func ConfigLocalScopeDefaultNetworks(defaultAddressPool []*NetworkToSplit) error

ConfigLocalScopeDefaultNetworks configures local default pool. Ideally this will be called during libnetwork init

func GetGlobalScopeDefaultNetworks

func GetGlobalScopeDefaultNetworks() []*net.IPNet

GetGlobalScopeDefaultNetworks returns PredefinedGlobalScopeDefaultNetworks

func GetLocalScopeDefaultNetworks

func GetLocalScopeDefaultNetworks() []*net.IPNet

GetLocalScopeDefaultNetworks returns PredefinedLocalScopeDefaultNetworks

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
