Functions ¶
func CreateAndSetupIpvlanSlave ¶
func CreateAndSetupIpvlanSlave(id string, slaveIfName string, netNs ns.NetNS, mtu int, masterDev int, mode string, ep *models.EndpointChangeRequest) (int, error)
CreateAndSetupIpvlanSlave creates an ipvlan slave device for the given master device, moves it to the given network namespace, and finally initializes it (see SetupIpvlanInRemoteNs).
func CreateIpvlanSlave ¶
func CreateIpvlanSlave(id string, mtu, masterDev int, mode string, ep *models.EndpointChangeRequest) (*netlink.IPVlan, *netlink.Link, string, error)
CreateIpvlanSlave creates an ipvlan slave in L3 based on the master device.
func DeriveEndpointFrom ¶
func DeriveEndpointFrom(hostDevice, containerID string, pid int) (*models.EndpointChangeRequest, error)
func Endpoint2IfName ¶
Endpoint2IfName returns the host interface name for the given endpointID.
func Endpoint2TempIfName ¶
Endpoint2TempIfName returns the temporary interface name for the given endpointID.
func Endpoint2TempRandIfName ¶
func Endpoint2TempRandIfName() string
Endpoint2TempRandIfName returns a random, temporary interface name for the given endpointID. This is similar to Endpoint2TempIfName() but uses a random string instead of endpoint ID.
func GetNetInfoFromPID ¶
GetNetInfoFromPID returns the index of the interface parent, the MAC address and IP address of the first interface that contains an IP address with global scope.
func GetVethInfo ¶
func GetVethInfo(nodeIfName string, parentIdx int, netNSMac string, ep *models.EndpointChangeRequest) error
GetVethInfo populates the given endpoint with the arguments provided where * nodeIfName - Node Interface Name * parentIdx - Interface Index of the container veth pair in the host side. * netNSMac - MAC address of the veth pair in the container side.
func IPv4Gateway ¶
func IPv4Gateway(addr *models.NodeAddressing) string
IPv4Gateway returns the IPv4 gateway address for endpoints.
