Golang NetworkSetNsFd Examples

Example #1

File: link_linux.go Project: drptbl/oz

// SetLinkNsFd sets the link's Linux namespace to the one specified by filesystem path.
func (l *Link) SetLinkNsFd(nspath string) error {
	fd, err := syscall.Open(nspath, syscall.O_RDONLY, 0)
	if err != nil {
		return fmt.Errorf("Could not attach to Network namespace: %s", err)
	}

	return netlink.NetworkSetNsFd(l.NetInterface(), fd)
}

Example #2

File: veth_linux.go Project: drptbl/oz

// SetPeerLinkNsFd sends peer link into container specified by path
func (veth *VethPair) SetPeerLinkNsFd(nspath string) error {
	fd, err := syscall.Open(nspath, syscall.O_RDONLY, 0)
	if err != nil {
		return fmt.Errorf("Could not attach to Network namespace: %s", err)
	}

	return netlink.NetworkSetNsFd(veth.peerIfc, fd)
}
