	Path        string
	NetconfPath string
}

type CNIPlugin

type CNIPlugin interface {
	GetPluginType() string
}

func GenerateCNIPlugins

func GenerateCNIPlugins(driver string, id int, ipam map[string]interface{}) ([]CNIPlugin, error)

type IPAMRoute

type IPAMRoute struct {
	Dst     string `json:"dst,omitempty"`
	GW      string `json:"gw,omitempty"`
	Gateway string `json:"gateway,omitempty"`
}

type IPRange

func ConfigLists

func ConfigLists(e *CNIEnv) ([]*NetworkConfigList, error)

ConfigLists loads config from dir if dir exists. The result also contains DefaultConfigList

func DefaultConfigList

func GenerateConfigList

func GenerateConfigList(e *CNIEnv, labels []string, id int, name string, plugins []CNIPlugin) (*NetworkConfigList, error)

GenerateConfigList creates NetworkConfigList. GenerateConfigList does not fill "File" field.
