Question

我今天重新安装了系统，由于无法使用kubectl describe访问我的Ingress，get可以正常工作并返回预期的Ingress。

kubectl describe ingresses
Error from server (NotFound): the server could not find the requested resource

这是我使用describe运行-v 8时得到的响应

GET host:443/apis/networking.k8s.io/v1beta1/namespaces/default/ingresses/ingress-rule
Request Headers:
    Authorization: Bearer TOKEN
    Accept: application/json, */*
    User-Agent: kubectl/v1.15.0 (linux/amd64) kubernetes/e8462b5
Response Status: 404 Not Found in 14 milliseconds
Response Headers:
    Content-Type: application/json
    Content-Length: 174
    Date: Wed, 10 Jul 2019 12:30:05 GMT
Response Body: {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"the server could not find the requested resource","reason":"NotFound","details":{},"code":404}

这是kubectl版本的结果

Answer 1

使用不同版本的kubectl客户端和服务器时遇到问题。您需要将kubectl客户端降级到1.12

在k8s v.15中，入口在networking.k8s.io组之前是"extensions/v1beta1"组的一部分

v1.19中的extensions / v1beta1将不再提供入口资源。从v1.14开始，可将其迁移至networking.k8s.io/v1beta1 API。可以通过networking.k8s.io/v1beta1 API检索现有的持久数据。k8s CHANGELOG-1.15.md

Answer 2

尝试运行

kubectl get ingress

如果您在名称空间中定义的入口不是默认名称，请使用以下内容：

kubectl get ingress -n <NSNAME>

一旦有了入口资源列表，就可以使用以下内容进行描述：

kubectl describe ingress <IngressName> -n <Namespace>

Kubectl desribe为Ingress返回404
