Functions

func GenerateNetworkInterfaceUnits

func GenerateNetworkInterfaceUnits(unitsPath string, netDescriptions []NetDescriber) error

func GetAppsResources

func GetAppsResources(apps schema.AppList) (totalCpus, totalMem int64)

GetAppsResources returns values specified by user in pod-manifest. Function expects a podmanifest apps. Return aggregate quantity of mem (in MB) and cpus.

func GetKVMNetArgs

func GetKVMNetArgs(nds []NetDescriber) ([]string, error)

type NetDescriber

type NetDescriber interface {
	GuestIP() net.IP
	Mask() net.IP
	IfName() string
	IPMasq() bool
	Name() string
	Gateway() net.IP
	Routes() []types.Route
}

NetDescriber is the interface that describes a network configuration

func GetNetworkDescriptions

func GetNetworkDescriptions(n *networking.Networking) []NetDescriber

GetNetworkDescriptions converts activeNets to netDescribers
