Implementing Rate Limit based on Nginx policy How to implement rate limiting in a virtual server

[datavisorrunziyang]

For a single nginx controller, the rate limit can be implemented accurately, but for multiple pods, the limit rate will double with the number of pods.

Hi @datavisorrunziyang , this feature was recently implemented. You can use the scale paramater on the rateLimit policy from version 3.6.0. You can see the docs on this here

Eg like this

apiVersion: k8s.nginx.org/v1
kind: Policy
metadata:
  name: rate-limit-policy
spec:
  rateLimit:
    rate: 1r/s
    key: ${binary_remote_addr}
    zoneSize: 10M
    scale: true
