openssl giving Kubernetes Ingress Controller Fake Certificate

问题

I have configured ssl certificate, if I visit https://<domain>.com, I see that my certificate is configured successfully but when I try to check certificate by following command

openssl s_client -connect <domain>.com:443 | openssl x509 -noout -subject -issuer

i am getting Kubernetes Ingress Controller Fake Certificate

My ingres config is :

  annotations:
    nginx.ingress.kubernetes.io/ssl-redirect: 'true'
    nginx.ingress.kubernetes.io/from-to-www-redirect: 'true'
  name: nginx-echo
spec:
  tls:
    - hosts:
      - domain.com
      secretName: domain.com
  rules:
    - host: domain.com
      http:
        paths:
        - path: /
          pathType: Prefix
          backend:
            service:
                name: website-lorem
                port:
                    number: 80

with command gives the same fake certificate: openssl s_client -connect <domain>.com:443 -servername <domain> | openssl x509 -noout -subject -issuer
