2

Please check the follwing link https://docs.traefik.io/middlewares/ipwhitelist/
I am quite sure you can do that with ipwhitelist

3

can this ipwhitelist block a ip?
how ?

4

Hello,
i dont think, i use iptables for that actually but for other reasons too

5

Any ip not in the list will be blocked.

IPWhitelist accepts / refuses requests based on the client IP.

It's clear in the documentation page. Did you check out?

6

the block ip is konw,but the ip allow come in is not know.

so ipwhitelist can not block one or two ip.

7

That is not true, ipwhitelist can block a list of ip(s) (CIDR or single one).

Can you explain what do you want to achieve ?

8

ipwhitelist is allow ip,not block

9

the docs not Explana how to refuses requests based on the client IP

or i don't know how to set it with kv

Have you tried?

apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: known-ips
  namespace: traefik
spec:
  ipWhiteList:
    sourceRange:
    - 0.0.0.0/0.  <--- remove it for allow only localhost and block all
    - 127.0.0.1/32

IPWhitelist works like a deny all policy, so you have to add the list of ips (CIDR) to allow access to your backend.
