Functions ¶
func ClearEntriesForIP ¶
ClearEntriesForIP uses the conntrack tool to delete the conntrack entries for the UDP connections specified by the given service IP
func ClearEntriesForNAT ¶
ClearEntriesForNAT uses the conntrack tool to delete the conntrack entries for connections specified by the {origin, dest} IP pair.
func ClearEntriesForPort ¶
ClearEntriesForPort uses the conntrack tool to delete the conntrack entries for connections specified by the port. When a packet arrives, it will not go through NAT table again, because it is not "the first" packet. The solution is clearing the conntrack. Known issues: https://github.com/docker/docker/issues/8795 https://github.com/kubernetes/kubernetes/issues/31983
func ClearEntriesForPortNAT ¶ added in v1.14.0
func ClearEntriesForPortNAT(execer exec.Interface, dest string, port int, protocol v1.Protocol) error
ClearEntriesForPortNAT uses the conntrack tool to delete the contrack entries for connections specified by the {dest IP, port} pair. Known issue: https://github.com/kubernetes/kubernetes/issues/59368
