Kubernetes 入口控制器无法找到证书机密

Question

我正在设置一个包含入口控制器证书的密钥，但是当我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"

秘密：

$ 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

下面是我的入口 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

      - backend:
          serviceName: hello-kubernetes-first
          servicePort: 80

    secretName: auth-tls

Ingress 和 Secret 都是命名空间资源。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namespace 内工作。因此，在您的用例中，您需要将它们（Ingress 和 Secret）放在同一个命名空间中。
