Functions

func CmdAdd

func CmdAdd(cniNetns, cniContainerID, cniIfname string, conf []byte, f func() error) (types.Result, []byte, error)

func CmdAddWithArgs

func CmdAddWithArgs(args *skel.CmdArgs, f func() error) (types.Result, []byte, error)

func CmdCheck

func CmdCheck(cniNetns, cniContainerID, cniIfname string, conf []byte, f func() error) error

func CmdCheckWithArgs

func CmdCheckWithArgs(args *skel.CmdArgs, f func() error) error

func CmdDel

func CmdDel(cniNetns, cniContainerID, cniIfname string, f func() error) error

func CmdDelWithArgs

func CmdDelWithArgs(args *skel.CmdArgs, f func() error) error

func NewNS

func NewNS() (ns.NetNS, error)

Creates a new persistent (bind-mounted) network namespace and returns an object representing that namespace, without switching to it.

func Ping

func Ping(saddr, daddr string, isV6 bool, timeoutSec int) error

Ping shells out to the `ping` command. Returns nil if successful.

func TmpResolvConf

func TmpResolvConf(dnsConf types.DNS) (string, error)

TmpResolvConf will create a temporary file and write the provided DNS settings to it in the resolv.conf format. It returns the path of the created temporary file or an error if any occurs while creating/writing the file. It is the caller's responsibility to remove the file.

func UnmountNS

func UnmountNS(ns ns.NetNS) error

UnmountNS unmounts the NS held by the netns object

Types

type BadReader

type BadReader struct {
	Error error
}

BadReader is an io.Reader which always errors

func (*BadReader) Close

func (r *BadReader) Close() error

func (*BadReader) Read

func (r *BadReader) Read(buffer []byte) (int, error)
