Ingress-Nginx配置修改

Ingress-Nginx配置修改

说明文档：https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/configmap/

将键值对添加到config-map的data部分。例如：

data:
  map-hash-bucket-size: "128"
  ssl-protocols: SSLv2

1）我们看到yaml文件里引用configmap名为：nginx-configuration

2）修改对应namespace下该文件后apply生效。(注意这里修改是全局生效的)

kind: ConfigMap
apiVersion: v1
data:
  client-header-buffer-size: 20m
  compute-full-forwarded-for: "true"
  forwarded-for-header: X-Forwarded-For
  large-client-header-buffers: 4 1024k
  proxy-body-size: 50m
  use-forwarded-headers: "true"
metadata:
  name: nginx-ingress-controller
  namespace: default
  labels:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/part-of: ingress-nginx

3）指定单个域名修改的话则在ingress的annotations下添加

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/proxy-buffer-size: "8k"
    nginx.ingress.kubernetes.io/proxy-body-size: 50m
    nginx.ingress.kubernetes.io/proxy-connect-timeout: "600"
    nginx.ingress.kubernetes.io/proxy-read-timeout: "600"
    nginx.ingress.kubernetes.io/proxy-send-timeout: "600"
