Kubernetes 入口控制器无法找到证书密钥

我正在设置一个包含入口控制器证书的机密，但在检查入口日志时出现以下错误

入口日志：

W0304 05:47:32.020497       7 controller.go:1153] Error getting SSL certificate "default/auth-tls": local SSL certificate default/auth-tls was not found. Using default certificate
W0304 05:47:32.020516       7 controller.go:1407] Error getting SSL certificate "default/auth-tls": local SSL certificate default/auth-tls was not found
I0304 05:47:32.114777       7 main.go:117] "successfully validated configuration, accepting" ingress="hello-kubernetes-ingress" namespace="default"

Secret:

$ kubectl create secret tls auth-tls --cert key.pem --key out.key
$ kubectl describe secret auth-tls
Name:         auth-tls
Namespace:    default
Labels:       <none>
Annotations:  <none>

Type:  kubernetes.io/tls

Data
====
tls.crt:  3231 bytes
tls.key:  1732 bytes

下面是我的 ingress yaml 文件

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: hello-kubernetes-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/auth-url: https://externalauthentication/authorize
spec:
  rules:
  - host: hw1.yourdomain
    http:
      paths:
      - backend:
          serviceName: hello-kubernetes-first
          servicePort: 80
  - host: hw2.yourdomain
    http:
      paths:
      - backend:
          serviceName: hello-kubernetes-second
          servicePort: 80
  tls:
  - hosts:
    - externalauthentication
    - hw1.yourdomain
    secretName: auth-tls

这俩Ingress和Secret是命名空间资源。您可以通过以下方式检查自己：

$ kubectl api-resources --namespaced=true
NAME                        SHORTNAMES   APIGROUP                    NAMESPACED   KIND
...
secrets                                                              true         Secret
...
ingresses                   ing          extensions                  true         Ingress
ingresses                   ing          networking.k8s.io           true         Ingress

他们只能在自己的范围内工作名称空间 https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/。因此，在您的用例中，您需要将它们都放在（Ingress and Secret）在同一个命名空间中。
