--enable-pprof Enables pprof for debugging performance and memory leak issues.
--excluded-cidrs strings Excluded CIDRs are used to exclude IPVS rules from deletion.
--gobgp-admin-port uint16 Port to connect to GoBGP for administrative purposes. (default 50051)
--gobgp-admin-port uint16 Port to connect to GoBGP for administrative purposes. Setting this to 0 will disable the GoBGP gRPC server. (default 50051)
--hairpin-mode Add iptables rules for every Service Endpoint to support hairpin traffic.
--health-port uint16 Health check port, 0 = Disabled (default 20244)
