ingress 中添加proxy-connect-timeout 超时时间不生效

在ingress注释中添加以下配置一直没有生效的状态

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/proxy-connect-timeout: '300s'
    nginx.ingress.kubernetes.io/proxy-read-timeout: '300s'
    nginx.ingress.kubernetes.io/proxy-send-timeout: '300s'
    nginx.ingress.kubernetes.io/rewrite-target: /$2

注意：改注释的value需要number类型，不能加s，否者不生效 正确的配置如下

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/proxy-connect-timeout: '300'
    nginx.ingress.kubernetes.io/proxy-read-timeout: '300'
    nginx.ingress.kubernetes.io/proxy-send-timeout: '300'
    nginx.ingress.kubernetes.io/rewrite-target: /$2
