如何在 traefik 入口 controller 中为 kubernetes 设置最大请求正文大小？

Question

It's very easy to set up max request body size with nginx using client_max_body_size directive. How can I do the same with kubernetes traefik ingress controller . I know there is maxrequestbodybytes directive to do so but, I'm lost with how to set it up in yaml file describing my ingress.

Wasn't so easy to figure this out. There is a funky multiline way of specifying this config in yaml file. Please check option traefik.ingress.kubernetes.io/buffering to see he pipe ( | ) oprator in acction.

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: example
  labels:
    domain: example.com
    deployment: production
  annotations:
    kubernetes.io/ingress.class: traefik
    traefik.ingress.kubernetes.io/frontend-entry-points: http
    traefik.ingress.kubernetes.io/buffering: |
      maxrequestbodybytes: 31457280
      memrequestbodybytes: 62914560
spec:
  etc....
