Types

type CNIEnv

type CNIEnv struct {
	Path        string
	NetconfPath string
}

type ConfigListTemplateOpts

type ConfigListTemplateOpts struct {
	ID           int
	Name         string // e.g. "nerdctl"
	Subnet       string // e.g. "10.4.0.0/16"
	Gateway      string // e.g. "10.4.0.1"
	ExtraPlugins string // e.g. `,{"type":"isolation"}`
}

type NetworkConfigList

type NetworkConfigList struct {
	*libcni.NetworkConfigList
	NerdctlID *int
	File      string
}

func ConfigLists

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

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

func DefaultConfigList

func DefaultConfigList(e *CNIEnv) (*NetworkConfigList, error)

func GenerateConfigList

func GenerateConfigList(e *CNIEnv, id int, name, cidr string) (*NetworkConfigList, error)

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