无法SSL通过入口Nginx控制器

Question

我有一个JavaSpring Boot Application，我已经将服务器配置为在SSL上运行，这是强制性的。

server:
  port: 8443
  ssl:
    enabled: true
    key-store-type: pkcs12
    key-store: ${KEYSTORE}
    key-password: ${KEYSTORE_PASSWORD}
    key-store-password: ${KEYSTORE_PASSWORD}
    client-auth: need

我已经为我的域创建了一个证书*。kahootali.com从LetsEncrypt证书，并通过运行为keystore创建了一个p12文件

openssl pkcs12 -export -CAfile ca.crt -in cert.pem -inkey key.pem -certfile cert.pem -out kstore.p12

我想用Ingress Nginx控制器在Kubernetes上公开它，所以我创建了一个秘密

kubectl create secret generic store --from-file=kstore.p12

我已经部署了应用程序，可以看到部署文件，当我将本地8443端口转发到其服务的8443并运行时

curl -iv --cacert ca.crt --cert mediator_cert.pem --key mediator_key.pem --resolve 'spring-app.kahootali.com:8443:127.0.0.1' https://spring-app.kahootali.com:8443/

它运行良好，并且可以返回

但当我为它创建一个入口并通过它的ssl时

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: spring-monitoring-app
  labels:
    app: spring-monitoring-app
  annotations:
    ingress.kubernetes.io/force-ssl-redirect: "true"
    ingress.kubernetes.io/rewrite-target: /
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/ssl-passthrough: "true"
spec:
  rules:
    - host: spring-app.kahootali.com
      http:
        paths:
          - path: /
            backend:
              serviceName: spring-monitoring-app
              servicePort: http
  tls:
    - hosts:
      - spring-app.kahootali.com
      secretName: tls-cert

它在浏览器和应用程序调试级别日志中给出了ERR_BAD_SSL_CLIENT_AUTH_CERT

Error during SSL handshake
java.io.IOException: EOF during handshake.
The SNI host name extracted for this connection was [spring-app.kahootali.com]
Handshake failed during wrap
javax.net.ssl.SSLHandshakeException: Empty server certificate chain

我发表评论是为了提高知名度：

根据文档，默认情况下禁用SSL直通功能。为了启用它，您需要使用--启用ssl passthrough标志启动nginx入口控制器。确保你没有忘记这件事。

您还可以查看此故障排除步骤，以验证nginx入口控制器的配置。

如果有帮助，请告诉我。
