-# Kube-proxy plugin for VPP {#kp_plugin_doc}
-
-## Overview
-
-This plugin provides kube-proxy data plane on user space,
-which is used to replace linux kernal's kube-proxy based on iptables.
-The idea is largely inspired from VPP LB plugin.
-
-Currently, kube-proxy plugin supports three service types:
-1) Cluster IP plus Port: support any protocols, including TCP, UDP.
-2) Node IP plus Node Port: currently only support UDP.
-3) External Load Balancer.
-
-For Cluster IP plus Port case:
-kube-proxy is configured with a set of Virtual IPs (VIP, which can be
-prefixes), and for each VIP, with a set of POD addresses (PODs).
-
-For a specific session received for a given VIP (or VIP prefix),
-first packet selects a Pod according to internal load balancing algorithm,
-then does DNAT operation and sent to chosen Pod.
-At the same time, will create a session entry to store Pod chosen result.
-Following packets for that session will look up session table first,
-which ensures that a given session will always be routed to the same Pod.
-
-For returned packet from Pod, it will do SNAT operation and sent out.
-
-Please refer to below for details:
-https://schd.ws/hosted_files/ossna2017/1e/VPP_K8S_GTPU_OSSNA.pdf
-
-
-## Configuration
-
-### Global KP parameters
-
-The kube-proxy needs to be configured with some parameters:
-
- ku conf [buckets <n>] [timeout <s>]
-
-buckets: the *per-thread* established-connections-table number of buckets.
-
-timeout: the number of seconds a connection will remain in the
- established-connections-table while no packet for this flow
- is received.
-
-### Configure VIPs and Ports
-
- ku vip <prefix> port <n> target_port <n> node_port <n> \
- [nat4|nat6)] [new_len <n>] [del]
-
-new_len is the size of the new-connection-table. It should be 1 or 2 orders of
-magnitude bigger than the number of PODs for the VIP in order to ensure a good
-load balancing.
-
-Examples:
-
- ku vip 90.0.0.0/8 nat44 new_len 2048
- ku vip 2003::/16 nat66 new_len 2048
-
-### Configure PODs (for each VIP)
-
- ku pod <vip-prefix> [<address> [<address> [...]]] [del]
-
-You can add (or delete) as many PODs at a time (for a single VIP).
-
-Examples:
-
- ku pod 90.0.0.0/8 10.0.0.1
- ku pod 2002::/16 2001::2 2001::3 2001::4
-
-### Configure SNAT
-
- ku set interface nat4 in <intfc> [del]
-
-Set SNAT feature in a specific interface.
-
-
-## Monitoring
-
-The plugin provides quite a bunch of counters and information.
-
- show ku
- show ku vip verbose
- show node counters
-
-
-## Design notes
-
-### Multi-Threading
-
-This implementation implement parallelism by using
-one established-connections table per thread. This is equivalent to assuming
-that RSS will make a job similar to ECMP, and is pretty useful as threads don't
-need to get a lock in order to write in the table.
-
-### Hash Table
-
-A kube-proxy requires an efficient read and write Hash table. The Hash table
-used by ip6-forward is very read-efficient, but not so much for writing. In
-addition, it is not a big deal if writing into the Hash table fails.
-
-The plugin therefore uses a very specific Hash table.
- - Fixed (and power of 2) number of buckets (configured at runtime)
- - Fixed (and power of 2) elements per buckets (configured at compilation time)
-
