如何设置Ingress-nginx自定义错误 [英] How to set ingress-nginx custom errors

问题描述

我使用kubernetes ingress-nginx控制器和GKE上的一组自定义错误，但是我遇到了一些问题.

I use the kubernetes ingress-nginx controller and a set custom errors on GKE but I have some problems.

目标: 如果something-web-app中发生50x错误，我将返回HTTP状态代码200和JSON {"status":200, "message":"ok"}

Goal: If a 50x error occurs in something-web-app, I'll return the HTTP status code 200 and JSON {"status":200, "message":"ok"}

问题:

1. 我已经阅读了自定义错误文档，但没有如何自定义default-backend的示例.

1. I have read the custom-errors document but there is no example of how to customize the default-backend.

我不了解ConfigMap和Annotation之间的区别.

I do not understand the difference between ConfigMap and Annotation.

ingress-nginx控制器首先如何工作.

How does ingress-nginx controller work in the first place.

推荐答案

您可以使用两种方式进行操作:

You can do it using two way :

1. 在入口中添加注释
2. 更改入口控制器configmap(更像beckend)

1 .尝试将此注释添加到kubernetes入口:

1. Try adding this annotation to kubernetes ingress :

nginx.ingress.kubernetes.io/default-backend:nginx-errors-svc

nginx.ingress.kubernetes.io/default-backend: nginx-errors-svc

nginx.ingress.kubernetes.io/custom-http-errors:404,503

nginx.ingress.kubernetes.io/custom-http-errors: 404,503

nginx.ingress.kubernetes.io/default-backend:错误页面

nginx.ingress.kubernetes.io/default-backend: error-pages

如果这样不起作用，请将其与两个一起添加:

If that doesn't work add this along with two :

nginx.ingress.kubernetes.io/server-snippet: |
      location @custom_503 {
        return 404;
      }
      error_page 503 @custom_503;

2.编辑配置图

您可以将此配置映射应用于入口控制器

You can apply this config map to ingress controller

apiVersion: v1
kind: ConfigMap
name: nginx-configuration-ext
data:
  custom-http-errors: 502,503,504
  proxy-next-upstream-tries: "2"
  server-tokens: "false"
