	// When creating non-default network without passing in `--subnet` option,

Functions

func ParseMTU

func ParseMTU(mtu string) (int, error)

ParseMTU parses the mtu option

func UsedNetworks

func UsedNetworks(ctx context.Context, client *containerd.Client) (map[string][]string, error)

Types

type CNIEnv

type CNIEnv struct {
	Path        string
	NetconfPath string
}

func NewCNIEnv

func NewCNIEnv(cniPath, cniConfPath string, opts ...CNIEnvOpt) (*CNIEnv, error)

func (*CNIEnv) CreateNetwork

func (e *CNIEnv) CreateNetwork(opts CreateOptions) (*NetworkConfig, error)

func (*CNIEnv) FilterNetworks

func (e *CNIEnv) FilterNetworks(filterf func(*NetworkConfig) bool) ([]*NetworkConfig, error)

func (*CNIEnv) GetDefaultNetworkConfig

func (e *CNIEnv) GetDefaultNetworkConfig() (*NetworkConfig, error)

GetDefaultNetworkConfig checks whether the default network exists by first searching for if any network bears the `labels.NerdctlDefaultNetwork` label, or falls back to checking whether any network bears the `DefaultNetworkName` name.
