Ingress 响应超时504故障排除

1. 故障现象:

在阿里云的ACK新上了一套系统.该系统有个将查询结果导出为excle并下载的功能,当第一次下载时等待1分钟后就跳出504,点击返回后再次下载可以正常下载.
在这里插入图片描述

2. 分析判断

根据504的页面应该是和Ingress配置相关
和超时时间长短有关

3. 排除过程

编辑Ingress

kubectl edit ingress/ehelp-ingress -n crm-web

在annotations下追加3行配置

    nginx.ingress.kubernetes.io/proxy-connect-timeout: "600"
    nginx.ingress.kubernetes.io/proxy-read-timeout: "3600"
    nginx.ingress.kubernetes.io/proxy-send-timeout: "3600"

具体如下:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    kubectl.kubernetes.io/last-applied-configuration: |
      {"apiVersion":"networking.k8s.io/v1","kind":"Ingress","metadata":{"annotations":{},"name":"crm-web-ingress","namespace":"crm-web"},"spec":{"rules":[{"host":"crm-web.mircosoft.com","http":{"paths":[{"backend":{"service":{"name":"crm-web","port":{"number":8080}}},"path":"/","pathType":"Prefix"}]}}]}}
    nginx.ingress.kubernetes.io/proxy-connect-timeout: "600"
    nginx.ingress.kubernetes.io/proxy-read-timeout: "3600"
    nginx.ingress.kubernetes.io/proxy-send-timeout: "3600"
    ...略
