Functions

func BuildCNIArgs

func BuildCNIArgs(args map[string]string) string

BuildCNIArgs builds cni args as string such as key1=val1;key2=val2

func CmdAdd

func CmdAdd(cmdArgs *skel.CmdArgs, networkInfos []*NetworkInfo) (types.Result, error)

CmdAdd saves networkInfos to disk and executes each cni binary to setup network

func CmdDel

func CmdDel(cmdArgs *skel.CmdArgs, lastIdx int) error

CmdDel restores networkInfos from disk and executes each cni binary to delete network

func ConfigureIface

func ConfigureIface(ifName string, res *t020.Result) error

ConfigureIface takes the result of IPAM plugin and applies to the ifName interface

func DelegateAdd

func DelegateAdd(netconf map[string]interface{}, args *skel.CmdArgs, ifName string) (types.Result, error)

DelegateAdd calles delegate cni binary to execute cmdAdd

func DelegateDel

func DelegateDel(netconf map[string]interface{}, args *skel.CmdArgs, ifName string) error

DelegateDel calles delegate cni binary to execute cmdDEL

func GetNetworkConfig

func GetNetworkConfig(networkName, confdir string) ([]byte, error)

func IPInfoToResult

func IPInfoToResult(ipInfo *constant.IPInfo) *t020.Result

IPInfoToResult converts IPInfo to Result

func ParseCNIArgs

func ParseCNIArgs(args string) (map[string]string, error)

ParseCNIArgs parses `key1=val1;key2=val2` format cni args from string

Types

type NetworkInfo

type NetworkInfo struct {
	NetworkType string
	Args        map[string]string
	Conf        map[string]interface{}
	IfName      string
}

NetworkInfo wraps network infos which are needed for cni plugin to setup network

func NewNetworkInfo

func NewNetworkInfo(networkType string, conf map[string]interface{}, ifName string) *NetworkInfo

NewNetworkInfo creates a NetworkInfo
