Types ¶
type Destination ¶
type Destination struct {
Address net.IP
Port uint16
Weight int
ConnectionFlags uint32
AddressFamily uint16
UpperThreshold uint32
LowerThreshold uint32
}
Destination defines an IPVS destination (real server) in its entirety.
type Handle ¶
type Handle struct {
// contains filtered or unexported fields
}
Handle provides a namespace specific ipvs handle to program ipvs rules.
func New ¶
New provides a new ipvs handle in the namespace pointed to by the passed path. It will return a valid handle or an error in case an error occured while creating the handle.
func (*Handle) Close ¶
func (i *Handle) Close()
Close closes the ipvs handle. The handle is invalid after Close returns.
func (*Handle) DelDestination ¶
func (i *Handle) DelDestination(s *Service, d *Destination) error
DelDestination deletes an already existing real server in the passed ipvs service in the passed handle.
func (*Handle) DelService ¶
DelService deletes an already existing service in the passed handle.
func (*Handle) NewDestination ¶
func (i *Handle) NewDestination(s *Service, d *Destination) error
NewDestination creates a new real server in the passed ipvs service which should already be existing in the passed handle.
func (*Handle) NewService ¶
NewService creates a new ipvs service in the passed handle.
func (*Handle) UpdateDestination ¶
func (i *Handle) UpdateDestination(s *Service, d *Destination) error
UpdateDestination updates an already existing real server in the passed ipvs service in the passed handle.
func (*Handle) UpdateService ¶
UpdateService updates an already existing service in the passed handle.
type Service ¶
type Service struct {
// Virtual service address.
Address net.IP
Protocol uint16
Port uint16
FWMark uint32 // Firewall mark of the service.
// Virtual service options.
SchedName string
Flags uint32
Timeout uint32
Netmask uint32
AddressFamily uint16
PEName string
}
Service defines an IPVS service in its entirety.
